HRV Balance : Check your autonomic nervous system balance frequently.

Alex.Kim — Wed, 14 Oct 2026 02:31:19 GMT

HRV Balance measures your autonomic balance from beat-to-beat (RR) intervals of the wrist optical sensor. Unlike overnight HRV status, it shows where you are right now: before a meeting, when you feel drained, or after a workout to check recovery.

https://apps.garmin.com/ko-KR/apps/adc47564-4c8d-4467-a887-58522171fd67

What you get
- SNS and PNS indices (0-100 each, 50 = healthy-adult average) and RMSSD, measured over 2-5 minutes (default 3) while you sit still.
- One of five states (Recovery, Balanced, Tension, Activation, Depletion) with a "Strong" marker when one side clearly leads, plus an RMSSD grade adjusted to your profile age.
- Advice pages for each result: typical pattern, common causes, body signs and what to do.
- Tags per measurement (time of day, situation, mood), 7-day and 4-week trends, and a filterable history.
- Built-in Help with figures and tables. 8 languages: English, Korean, German, French, Spanish, Japanese, Traditional and Simplified Chinese.

How to use
Wear the band snug, one finger above the wrist bone, sit down and rest your arm. Start the app, wait for "Ready", press START and stay still for 3 minutes. The watch vibrates when done and shows the result; press DOWN for the advice pages.

Notes
- The app needs the optical sensor in high-rate mode. If no pulse signal arrives within 30 seconds, the app tells you; exit with BACK and start it again, the second launch usually locks within a few seconds.
- Screen-on time follows your watch setting (System - Display - During Activity - Always On).
- A temporary recording session keeps the sensor active; nothing is saved to Garmin Connect.
- Free, no ads. Personal wellness reference only, not a medical device and not a diagnosis.

CyberWolf: Robot Revolt

LukasPrvy — Sat, 10 Oct 2026 01:38:19 GMT

CyberWolf: Robot Revolt is a full single-player sci-fi/horror shooter built for the Garmin watch. Fight your way through ten decks of a dark mining ship, from the cargo ramp to the bridge, against the ship's own robots.

I would love to share this game with you, unfortunatelly it's stuck 6th day in "pending" state.

Start timer and practice for Slalom and Course race sailing races free app

Alex Olaf — Fri, 09 Oct 2026 13:51:31 GMT

Actually app is available couple of months mostly used inside local community.

No i believe the app is stable enough, so i can try show it to the public.

It has a start timer mimics Optimum Timer beeper scheme, accompanied by vibrations.

For a newbies or solo training there has a prediction feature shows are you going to be late or too early on start line

and help you do a starting procedure suggesting the time to turn and vibrating then it's time to jybe.

For the practicing and gear tuning it is very handy to see the top speed for previous tack and the history.

So you can tune the gear, make a few tacks, check if top speeds got better and tune again.

Watchface: FaceForge – a watch face drawn from your sentence or a photo

9014880 — Thu, 08 Oct 2026 19:58:21 GMT

Hi all. I am a trail runner in Ljubljana and I built FaceForge because I wanted the view from my window on my watch, not a photo cropped behind six templates. Then got completely excited when I could make a small climber ascend the mountain with my steps.

How it works: install the face, go to the web app and describe what you want ("a red lighthouse on a rocky bay at dawn"), use a photo or find a mountain you love. It draws a scene, you drag your numbers where you want them, add effects like sun moving through the day, weather, various items moving as you accumulate your steps, etc.. When you finish the face arrives on the watch by itself in about fifteen minutes. Works on MIP (I have a Forerunner 955 and love it) and AMOLED.

Drawing and changing is free; keeping a face costs €3.99 once, no subscription.

Store link here

I'd love to know where it breaks on your model. If you want to try it let me know, I can give you the face code for free, I'm mostly looking for feedback here.

And if it is on your wrist and you like it, a rating in the Connect IQ app helps a one-person shop more than anything else.

Delays in Reviewing Pending Watch Faces

4988690 — Thu, 08 Oct 2026 13:59:41 GMT

I have about 16 watch faces that haven't been approved yet because they're showing as “Pending.”

Some have been in that status since September 30. I understand that the team might be overwhelmed, but please remember that many of us developers earn income from these products we create for Garmin users.

Anyone else having the same problem?

Fenix 5 Only works when connected to power

paulturner3 — Tue, 06 Oct 2026 01:55:03 GMT

I a have a Garmin Fenix 5X

Mine went off randomly AI told me it was the battery. I figured it’s 10 years old probably right got a new battery. Installed it exactly the same problem..

I’ve done everything that everyone else has said, hold down the top left button one minute two minutes 30 seconds three buttons, charged for two hours unplugged it left for 20 minutes. Did the whole deal charge for another two hours still doesn’t work!

When plugged into power it will turn on and power up works normally, battery showing up now as 100% charged soon as you take the power out it’s off.
the inside is pristine no water ingress no visible signs of any damage.

Does anyone know a fix without replacing the the watch?

[NEW APP] WaySense - Know When You'll Arrive

LSI Tech — Mon, 05 Oct 2026 17:40:15 GMT

I built WaySense, a Garmin data field designed to answer one simple question: when will I arrive?

It estimates your arrival time based on your actual moving pace during the activity. Stops do not artificially lower your average pace, while breaks are still taken into account in the final ETA.

WaySense also tells you if you're likely to arrive after sunset or in the rain, based on the time remaining and current weather conditions.

The goal is to put the information that actually matters during a long activity directly on your watch, without filling the screen with unnecessary data.

WaySense is available on Connect IQ:

https://apps.garmin.com/apps/fb6c0fcd-b69a-4f39-8075-669e9c185852

I'm the developer behind the app, so feedback from Connect IQ developers and Garmin users is very welcome.

New free data field: WattPace - FTP pacing + fueling alerts for triathlon & cycling

4159015 — Sun, 04 Oct 2026 22:34:49 GMT

Hi all, just published my first Connect IQ data field and wanted to share it here.

WattPace shows FTP-based target power for your race distance (TT/crit, Olympic, 70.3, full-distance), with the whole screen changing color (red/green/blue) based on whether you're over, on, or under target - adjustable sensitivity from ±10 to ±30W. It also runs a customizable fueling-alert timer that checks current heart rate against your threshold before recommending carbs vs. water only, and logs both pacing and fueling data as custom FIT fields for post-ride review in Garmin Connect.

Built and tested across roughly 90 devices spanning fenix, epix, Forerunner, Edge, Enduro, MARQ, Descent, and D2. Free, no ads, no data collection.

Link: https://apps.garmin.com/apps/92627ae0-79d9-4837-9371-3625d31d7044

Happy to take feedback or bug reports here - this is a labor of love from my own racing as a junior national-level triathlete, genuinely want it to be useful for others too.

[App] Dead Run: free zombie-chase running app — feedback welcome

4890135 — Sun, 04 Oct 2026 08:19:00 GMT

I made Dead Run, a free running app where your pace controls a zombie chase on your watch.

Press START and the chase begins alongside your run recording. Running faster than the zombies widens the gap, but they gradually accelerate. Getting caught ends the game, not your recorded run. You can pause the run and chase together.

It's available here: apps.garmin.com/.../d58db356-9795-443f-b8c8-4c63f105bfa6

I'd appreciate feedback on whether the listing makes the game clear. Before installing, is anything confusing or missing? If you try it, was the gap display easy to understand?

The game deliberately becomes impossible. Pause at crossings and whenever needed; don't exceed your safe exertion to avoid getting caught.

[App] GKG: your Google Keep lists on the watch, tick items off from the wrist (free, open source)

suskozaver — Sat, 03 Oct 2026 08:33:09 GMT

Hi all,

GKG shows your Google Keep lists on your watch, and you can tick items off from the wrist. The ticks go back to Keep.

The catch, and why it's self-hosted: Google's Keep API is only open to Workspace admins. So GKG has a small server in between. It uses gkeepapi, the unofficial client that signs in with a master token, the same way an Android phone does. That token opens your whole Google account, not only Keep. That's why the server runs on your own machine and the token never leaves it. Nothing goes to me.

How it works:
watch → (Bluetooth) → phone → (HTTPS) → your GKG server → Google Keep

- pick which lists show up on the watch
- tick items off, the changes sync back to Keep
- the token is stored encrypted on your server

What you need:
- a machine with Docker
- a domain with a valid HTTPS certificate, reachable from the internet (the watch talks to it through your phone)
- clone the repo, fill in .env, docker compose up, create your account, connect Google on the Keep page
- then install GKG from the Connect IQ store, put your server address in its settings and link the watch with a 6-digit code

Watches: 74 round watches with buttons.

Free and open source (MIT)!

GitHub: https://github.com/suskozaver/gkg

If running your own server isn't your thing, this one isn't for you, and that's fine. If it is, I'd like to hear how the setup went.

[App] Eat Train Feel: AMRAP and rounds workouts on your watch, a lap for every exercise (free)

suskozaver — Sat, 03 Oct 2026 08:22:07 GMT

Hi all,

I'd like to show a Connect IQ app I've been building since the summer. It's the watch part of Eat Train Feel, a web app for workouts, food and how you feel, with a coach mode for personal trainers.

Why: I train at home with my fenix 8 on the wrist. Mostly AMRAPs and rounds, a SkiErg, a RowErg, an Echo Bike and a few weights. Getting that kind of workout onto the watch from another app was always the "did it sync?" game. Sometimes it worked. Sometimes it didn't. So I built the watch part myself.

How it works:
- link the watch once. The app shows a 6-digit code, you type it in Eat Train Feel under Settings › Garmin / Amazfit
- today's plan is simply on the watch. Your own workouts and whatever your coach assigned
- built something new and want it now? "Send to watch" on the workout page

On the watch:
- a heart rate band across the top in the colour of your Garmin HR zone
- a ring around the edge with the time left (AMRAP) or exercises left (rounds)
- elapsed and remaining time, the exercise, the reps, the weight, and NEXT
- LAP for the next exercise, two buzzes when a new round starts, one buzz a minute before the end
- DOWN for a second screen with calories, average heart rate and rounds
- long exercise names scroll, the font never shrinks

After the workout it's saved as a Cardio activity with a lap for every exercise, so Garmin Connect gets it like any other workout. Calories and heart rate come from Garmin. The result also goes back into the Eat Train Feel log by itself, and to your coach if the workout came from them.

Watches: 74 models, fenix 5 Plus and newer, Epix, Forerunner, Enduro, MARQ, Descent. Built on a fenix 8 AMOLED 51 mm.

One honest note: the watch app needs a free Eat Train Feel account. It's a soft launch, so sign-up is by request for now and you get an invite link by email, usually within a few hours.

Free, no ads, no trackers.

[App] Nordic — Free sauna, cold plunge & contrast-session timer

spboyer — Thu, 01 Oct 2026 19:58:22 GMT

Hi everyone—I'm the developer of Nordic, a free Connect IQ app for tracking sauna, cold plunge, and alternating hot/cold sessions.

I built it around physical buttons and a readable timer, with manual phase changes rather than a preset routine telling you when to move on.

What it does

Sauna: Time a session with the watch kept outside the sauna.
Cold Plunge: Track a standalone plunge, operating the buttons above water.
Nordic Cycle: Move through sauna, transition, cold plunge, and rest phases, with round counts and separate phase totals.
Activity recording: Save sessions as generic Garmin activities with phase-boundary laps.
Optional ANT+ heart rate: Use a compatible paired chest strap, with an indication when readings are missing.
Pause and recovery: Pause/resume, confirm before discarding, and recover a checkpointed local summary after an interruption.

There’s no subscription, separate Nordic account, or required companion app. You can use it without a heart-rate strap.

Compatibility

Check the Compatible Devices section of the store listing for the current supported models:

Download Nordic from Connect IQ

Important limitations

Keep your watch outside the sauna and within its manufacturer’s temperature limits. Timings follow your button presses; they are not automatic measurements of heat or cold exposure.

Operate buttons above water. Chest straps have their own temperature and water-use limits, and ANT+ reception can drop underwater or out of range. Nordic does not provide stored-HR backfill or Bluetooth strap support.

This is a timer and activity logger—not a medical device or an indication that it’s safe to remain in heat or cold.

Feedback welcome

I’d appreciate feedback on button behavior, screen readability, phase tracking, and how saved activities appear in Garmin Connect. If you report an issue, please include your watch model, firmware version, and the steps to reproduce it. Please don’t post private health data.

Free Garmin indoor workout app — structured bike and run workouts with smart-trainer support

9185584 — Thu, 01 Oct 2026 17:42:04 GMT

I’m the developer of a free Connect IQ device app that connects compatible Garmin watches to BLE fitness equipment using the standard Fitness Machine Service (FTMS).

The app supports two modes:

Bike: reads speed, cadence and power, and can request ERG target power on equipment that reports the required capability and grants control.
Treadmill: reads speed and incline, and can request supported target changes after capability checks and a second confirmation.

Sessions can be saved as FIT activities for Garmin Connect. If control is unavailable, rejected or disconnected, the app disables control or continues in read-only mode where possible.

I’m looking for testers with real FTMS equipment. If you try it, please reply with:

Garmin model
Fitness-machine model
Machine firmware
Bike or Treadmill mode
Metrics visible in the app
Whether control was offered and whether it worked
Whether the FIT activity saved successfully

Safety note: this app is not an emergency stop. Always use the machine’s physical STOP button, safety key and built-in safety systems. Start treadmill testing at low speed and zero incline while standing on the side rails.

[Watch Face] Expedition 01 · Summit Gauge — analog instrument-style dial

3379279 — Wed, 30 Sep 2026 12:08:25 GMT

Hi everyone,

I’d like to introduce Expedition 01 · Summit Gauge, my analog watch face with an instrument-style dial.

The layout centres on three hands, red hour markers and a dark industrial background. Altitude sits at the top, heart rate to the left, the date to the right and weather below, giving it a different emphasis from my Elegant and Carbon designs.

Key features:

[Watch Faces] Oktober - Munich Fest / Oktober - Wiesn night — Bavarian designs

3379279 — Wed, 30 Sep 2026 11:58:11 GMT

Hi everyone,

I’m the developer behind BackyardBull. I’d like to share Oktober - Munich Fest and Oktober - Wiesn night, two separate watch faces inspired by Munich and Oktoberfest.

Munich Fest uses Bavarian blue and white, traditional lettering and a Munich skyline. Wiesn night takes the evening view, with festival lights and warm gold details. Both keep everyday Garmin readings below the clock.

Key features:

Each app offers a 24-hour digital display or two central analog hands.
Switch Digital/Analog in Connect IQ or directly in the watch face settings.
Heart rate, daily steps, watch battery and Garmin weather with temperature in Celsius.
English date, with fixed colours and data field positions.
No visible always-on display: the screen is black while asleep.

In Analog mode, the hands pass over the artwork and can cover a data field. The images above are design previews with sample values.

Connect IQ:
Oktober - Munich Fest
Oktober - Wiesn night

Each is a separate paid app, currently €2.49 in the German store. Munich Fest supports the listed fēnix 8, quatix 8 and tactix 8 AMOLED models. Wiesn night also supports other listed 454 × 454 AMOLED watches, including Forerunner 965/970 and Venu 3. Please check each listing’s Compatible Devices tab.

Which version do you prefer? I’d particularly appreciate feedback on readability and the balance between the artwork and data. Questions, suggestions and bug reports are welcome in this thread.

next level HRV — HRV testing combined with your longitudinal Garmin health data

5638179 — Wed, 30 Sep 2026 11:22:04 GMT

HRV+ is a Garmin Connect IQ app for deliberate, timestamped HRV measurements.

Instead of relying only on passive daily summaries, HRV+ lets the user create a controlled measurement event at a specific point in time and capture:

RMSSD
mean HR
measurement duration
signal quality / motion context
exact timestamp for later correlation

The interesting part is not the isolated session itself. The session becomes much more useful when it is combined with the longitudinal data already available from Garmin:
(for that just connect the App with the DreamDoc Backend and HRV+ is generating reports correlated with your Garmin health data)

overnight HRV
resting HR
sleep
stress
respiration
activity / workouts
recovery-related trends
personal baseline changes over time

So the HRV session becomes an event marker inside a physiological time series.

Examples:

08:10 — morning HRV test
previous night — reduced sleep duration, elevated overnight stress
previous 48 h — higher training load
current result — RMSSD below individual baseline

Or:

18:00 — pre-intervention HRV
18:20 — breathing / recovery session
18:25 — post-intervention HRV

Now you can compare an intervention against the person’s own recent physiological state instead of interpreting one number in isolation.

That is also how we use the data in DreamDoc: combining active measurements + passive longitudinal wearable data + personal baselines to detect meaningful changes and understand context around them.

HRV+ is free on Garmin Connect IQ:
https://apps.garmin.com/apps/c813d8e3-7092-41c1-a167-14cf4eaab491

I’m particularly interested in feedback from people working with HRV analytics, recovery models, physiological time-series data or health data in general.

Glass Cards: an AMOLED watch face built with Reddit testers, and a QR code on the end-of-trial screen

6358344 — Tue, 29 Sep 2026 15:39:26 GMT

Hi all, I'm Mario, a one-person watch face developer. I wanted to share Glass Cards and two things I learned building it that might be useful to other devs.

Glass Cards is a calm AMOLED face: a big, light time and frosted-glass cards over a soft gradient (or pure black). You choose what goes on each card: heart rate, Body Battery, steps, VO2 max, training status, the time of your next calendar event, a second time zone and more. There are two layouts: 2 cards + bar + goal ring, or 4 cards + bar.

It went through 27 versions in about two weeks, almost all from Reddit testers' requests: the calendar card, the second time zone, icon-only cards and colours that rotate through the day. One tester measured the always-on drain on an Epix Pro before and after an optimisation (0.81% to about 0.71% per hour).

1. A QR code on the end-of-trial screen. Most people who saw the unlock code never typed it on the payment site. Now the screen also draws a QR (version 3, byte mode, level M) that opens the payment page with the code already filled in. It's encoded once in Monkey C and cached as 29 integers, one per row, and drawn as horizontal runs, so there's no cost per frame. It only appears on AMOLED screens of 390 px or more: on MIP and small screens the plain text screen stays, because a phone doesn't reliably read a QR from a reflective display. The code stays visible under the QR for anyone who can't scan.

2. Long lines on round screens. The Spanish texts are longer, so each line is measured against the width of the circle at its height, and if it doesn't fit, it falls back to a shorter version instead of being clipped.

Feedback is very welcome, from developers and users alike. What would you add to it?

[Widget] AirDust 5.6.135: air quality, pollen, UV and a lightning card (Pro)

Ivaylo Minkov — Tue, 29 Sep 2026 12:47:50 GMT

I'm the developer. AirDust is a Connect IQ widget that shows live air quality (PM2.5, PM10, AQI) from nearby Sensor.Community citizen sensors. The free tier needs no account. Pro is an optional one-time EUR 5 unlock (no subscription) that adds pollen, UV, history, alerts and, new in 5.6.135, lightning.

New in 5.6.135 (Pro):

• Lightning card: when a recent strike is found near you it shows distance, compass direction and strike age, marked as approximate. When a storm's movement is known it adds speed and Approaching / Moving away / Passing. If there is nothing recent there is no card, on purpose: the widget never shows an "all clear".

• Menu, then Check lightning: runs a check on demand (one per 5 minutes).

• Lightning Alerts (off by default) with a range of 5 to 50 km. They are evaluated while the widget is open, not in the background.

• Sun & UV screen rewritten: UV advice, and the current UV with its source and age. On solar watches it also shows the live solar charging signal; it does not measure sun exposure.

• Pollen and UV alerts no longer fire on old readings.

• The Air card names a thunderstorm when a fresh weather report says so.

• Stability and memory fixes.

Limits, plainly: strike data is minutes old, distances are approximate, and this is a convenience check, not an official warning. Follow local severe-weather guidance. The Pro carousel screens are not on every model; some smaller devices show simplified screens.

Data: lightning powered by Vaisala Xweather (https://www.xweather.com/); air quality from Sensor.Community (ODbL).

Lost developer signing key: can I still update my Connect IQ Store app?

6672389 — Mon, 28 Sep 2026 15:34:55 GMT

I publish the watch app SaunaGray on the Connect IQ Store). It's had about 29 releases, up to v0.0.29.

When I tried to upload v0.0.30, the Store rejected it with:

▎ Signature check has failed. All app versions must be signed with the same key pair.

I no longer have the original developer key that signed the earlier versions. <one sentence on what happened, e.g. "It was on a previous machine that has since been wiped."> The key on my current machine is a new one. I've already searched my backups.

My questions:

1. Can Garmin reset or re-associate the signing key for an existing app if I prove I own the developer account?
2. If not, is publishing a new app with a new app ID the only option? And is there an official way to point existing users of the old listing to the new one?
3. Can any user data (Application.Storage or settings) move across to a new app ID, or is it always lost?

Thanks for any help, and a reminder to others to back up
