I would like to understand how Garmin decides which apps to feature and which not, or how to draw Garmin's attention to its program.

iOS and Garmin Connect integration

ChristiaanSt — Wed, 20 May 2026 06:41:36 GMT

Hi Everyone

I am publishing an iOS app to the Apple App Store that uses the Connect IQ Mobile SDK for iOS to communicate with Garmin watches via the Connect IQ ecosystem. Apple has requested written confirmation under App Store Review Guideline 5.2.1 that Garmin authorises this use case. Does anyone know where I can find a letter that provides:

The Connect IQ Mobile SDK for iOS is licensed for commercial distribution through the Apple App Store, and
My use of the Garmin name in app metadata to describe compatibility is consistent with Garmin's trademark guidelines.

Or if anyone has had a similar issue what did they do to get it approved?

Thank you!

iOS app Approval using Garmin

ChristiaanSt — Tue, 19 May 2026 17:22:35 GMT

Hi all, please can someone help me??

The Connect IQ Mobile SDK for iOS is licensed for commercial distribution through the Apple App Store, and

My use of the Garmin name in app metadata to describe compatibility is consistent with Garmin's trademark guidelines."

My Garmin app is live and on the IQ store and downloadable and the iOS app is working but I am unable to publish the iOS app because of this

I’m trying to find an app to help with pacing for MECFS. I understand that there is a pacing watch face available, but it doesn’t provide alerts for high heart rate. Does anyone know if this function is being developed or is available elsewhere? I know tha

Pacing app with high heart rate alerts?

Can it be made possible to set the width of the course line?

7760082 — Sun, 17 May 2026 17:08:24 GMT

I find the course line on the map difficult to see because it is so narrow. Also, I'm colour blind, the contrast is also a bit low in the standard settings. But most of all: I would like the course line to be more fat - like Wahoo has. This is a massive usability upgrade.

Can it be made possible to set the width of the course line in an update?
Either in an app setting or by making it possible for devs to make a custom map theme that does accept line with settings.

Thanks!

App occasionally exits unexpectedly to glance carousel on physical device

the-ninth — Sun, 17 May 2026 08:21:51 GMT

I am seeing an issue where my app exits unexpectedly when running on a physical device, an Epix 2 Pro with the latest firmware.

I have debug logging in place, and it shows that the code paths in my app which are supposed to exit the app are not called. In my case, that would be the delegate’s onBack() method calling WatchUi.popView().

I cannot reliably reproduce the issue. It just happens occasionally. It also happens while I am actively interacting with the app, so it does not seem to be related to the app being terminated after a period of inactivity. Also, when this happens, the app exits back to the glance carousel rather than the watch face, which is what normally happens after inactivity.

Has anyone seen something like this, or does anyone have an idea what could cause it?

The app performs communication requests and displays full-screen custom views to the user. It does not use specialized view types such as Menu2 or CustomMenu.

Is there a way to develop apps in C?

7057491 — Fri, 15 May 2026 17:03:17 GMT

I understand that using Monkey C and its managed environment might be the only officially supported (and likely by far the most effective) way of developing apps for a Garmin Watch, but I'd like to, for educative purposes, experiment with embedded development. Being able to get into this with my Garmin watch would be perfect.

I don't plan on making an app to publish on the IQ store, or that works across multiple devices, just personal use and experimentation.

It seems unlikely to be possible due to possible restrictions on the system's app model, but I still figured it'd be worth asking.

Out Of Memory Error “Failed loading application” before getGlanceView() on CIQ 3.4 devices

the-ninth — Thu, 14 May 2026 17:06:32 GMT

Hi,

when starting my app on a CIQ 3.4 device with 32 kB glance memory, such as the Fenix 6 Pro or Forerunner 945 LTE, I get an Out of Memory Error: Failed loading application.

The error occurs before the glance is started. AppBase.getGlanceView() has not been executed yet. The stack trace points to a seemingly random file that is not even part of the glance scope.

When I start the glance on a device with 64 kB glance memory, it only uses 13 kB of memory, with a peak usage of 15 kB. So this does not really seem to be caused by a lack of memory.

What else could cause such an error?

Here is the error message:

Error: Out Of Memory Error
Details: Failed loading application
Stack: 
  -  at D:\GitHub\ohg\source\main\data\communications\connection\RequestUiUpdateTask.mc:11 0x80000000 

Encountered app crash.

For reference, here is the code base, including the file the error points to:

Cannot install prg file to real device on MacOS

1525726 — Thu, 14 May 2026 04:57:28 GMT

As mentioned, I cannot install built prg file to my real device on MacOS because GARMIN volume is not available when I plug the charge cable in.\

How can I solve that?

Connect Developer Program access form unavailable, anyone got through recently?

9311735 — Wed, 13 May 2026 21:02:54 GMT

Hi,

I'm working on a running coaching app with generated training plans. Strava is already integrated and we'd like to push our workouts to athlete Garmin watches via the Training API.

The access request form has been showing "Stay tuned" for weeks.
I emailed connect-support@developer.garmin.com on April 16 with all the details, no answer so far. Saw the other thread from March about the same problem.

Is the program currently paused? Is there any other way to apply? Just trying to figure out whether to wait or look at something else.

Also, has anyone here used anything else to push workouts to Garmin watches?
Would love to hear if it actually works in practice.

Thanks,
Jacques-Antoine

How to get zones from method UserProfile.getPowerZones()

ejdevries — Tue, 12 May 2026 20:39:24 GMT

In SDK 9.1.0 four methods were added to UserProfile: getHeartRateZones2(), getPowerZones(), getFunctionalThresholdPower() and getCurrentSport2().
I can get data from three of them but not from getPowerZones(), it returns null.

I tried it in the simulator and on my Edge 1050.
Did anyone try and succeed?

This is what I coded to test the method:

if (UserProfile has :getPowerZones) {
System.println("Using getPowerZones from UserProfile");
var sport = UserProfile.getCurrentSport2();
var pZones;
System.println("sport: " + sport);
if (sport != null && sport.size() > 0) {
System.println("Using getPowerZones for sport: " + sport[0]);
pZones = UserProfile.getPowerZones(sport[0]);
System.println("pZones1: " + pZones);
}
}

Automatically added support for new devices

trudelta — Tue, 12 May 2026 19:53:33 GMT

I noticed for the D2 Mach 2 Pro, that over the course of a few days or weeks, support for the new model was automatically added to all my apps (that already supported the D2 Mach 2). I am wondering if that will happend for the Forerunner 70, 170 and 170Music too, or if I will need to rebuild the apps including the new models.

Getting 404 error when editing Application.properties data on the CIQ Simulator

mulo76 — Tue, 12 May 2026 15:23:41 GMT

I'm getting the following error when editing application properties via the simulator, was working earlier today.

Now it is failing for all devices and even all watch face projects I run.

Any solutions to this?

Thanks Colm

How to detect alert?

pdurys — Sun, 10 May 2026 15:42:31 GMT

I do not know which watches has this feature but at least on my FR955 (with latest beta) I have Jeff Galloway Alert in standard Run activity app

Does someone know if there is possible to detect that alert event?
This alert is inside Run --> Run Settings --> Alerts

Similarly detect eg. when Drink or Eat alerts were triggered.

Thanks

Accessing Saved Waypoints from a Connect IQ Data Field on Edge 1040

Fohnbit — Sun, 10 May 2026 07:36:33 GMT

Hi everyone,

I am building a Connect IQ data field for Garmin Edge 1040 and I am trying to understand whether saved waypoints can be read directly inside a data field app.

My use case:

I want to alert the rider when approaching refill points.
Refill points are saved as waypoints on the device.
In my data field, Activity.Info.nameOfNextPoint and distanceToNextPoint mostly return the next turn instruction, not the saved waypoint I expect.
I can see saved waypoints elsewhere in the Edge UI, but I cannot reliably access them as “next relevant waypoint” from the data field.

What I tested:

Activity.Info:
- nameOfNextPoint
- distanceToNextPoint
- nameOfDestination
- distanceToDestination
PersistedContent classes (Waypoint/Route/Course), but in this context I only found metadata-level access (name/id/intent), not a clear way to get usable waypoint coordinates/list for my data field logic.

Questions:

Is it currently possible for a data field to read saved waypoints (including location) from device storage?
Is there any supported API path to access course points/waypoints (not just next turn text) in a data field?
If not, is this a known limitation on Edge devices, and is there a recommended workaround?

Any guidance or confirmation from Garmin team or developers who solved similar use cases would be very helpful.

Thanks!

Switch between calls depending on device api level? (ActivityRecording vs Activity)

fuselage — Fri, 08 May 2026 12:31:52 GMT

I have an app where Fenix5 users reported crashes wereas my F5plus worked fine. I think I tracked it down to the ActivityRecording and enums of the sport/subsport.

_session = ActivityRecording.createSession({

:name => "Yada yada",

:sport => Activity.SPORT_RUNNING,

:subsport => Activity.SUB_SPORT_GENERIC

});

F5plus is on api level 3.3 and F5 is on api level 3.1. The issue is that the enum in Activity was introduced in 3.2. Before that the enum resides in ActivityRecording.

What is the proper way to handle this? Check for api level (how?) and use

ActivityRecording.SPORT_RUNNING

if its a F5 and use

Activity.SPORT_RUNNING

if it's a newer device?

Comm.makeWebRequest() returning -400, 415 Unsupported Media Type

trudelta — Fri, 08 May 2026 01:38:10 GMT

All of a sudden previously working communication code that calls Comm.makeWebRequest() to request JSON data in the simulator return a -400 result code and this result in the body:

<body>
<center><h1>415 Unsupported Media Type</h1></center>
<hr><center>openresty/1.29.2.3</center>

I am using connectiq-sdk-win-9.1.0

What's going on? Is anyone else seeing this?

How to manage Heart Rate History within simulator?

2230226 — Thu, 07 May 2026 21:09:22 GMT

I am developing an app involving previous and current HR history, pulling from SensorHistory.getHeartRateHistory().

When using the ConnectIQ Simulator and testing my app, it gives some random history of heart rate of which I am unable to see or affect. For example, if I want to aggregate all time the user has spent in z1, z2, etc., it is automatically returning 48 "zone minutes" (vigorous or z3+ minutes) every app startup.

I have checked my calculations and code many times over and the only thing I can surmise is that there is some storage of HR history pulled when I run this code:

var iter = SensorHistory.getHeartRateHistory({
            :startTime => getMidnight(),
            :order => SensorHistory.ORDER_NEWEST_FIRST
        });

Which I expected obviously but the problem is that I have literally no way to affect what the simulator is giving to my running application

When I upload the app to my Forerunner 970 it works completely normally and scores everything correctly since it's using real, accurate data. My issue is I have almost no way of accessing the HR history data uploaded to simulator.

The reason this is blocking me is that if I want to have something happen when most of the day is spent at a lower HR, I have literally no way to test that except being idle myself all day and uploading to my watch personally. There is 0 way for me to put in the simulator that the dummy user spent 0 minutes at an intense heart rate.

Does anyone have experience changing this data? I have tried resetting simulator, app data, etc., nothing changes

Switch between watches in the simulator ?

I'm testing my data field on different watches in the simulator, but how can I quickly switch between watches in the simulator, if it is possible ?

Custom focus mode with CIQ app

Gabor — Wed, 06 May 2026 12:01:50 GMT

I can't seem to be able to trigger a specific focus mode with CIQ apps.

I create a new activity type focus mode (Enduro 3), select my app as auto-trigger, and whenever I start the app, only the generic, default Activity focus mode is being triggered.

This doesn't seem to work with other third party activity apps either. But works with native activities, also works with custom activities created on the phone.

Is this intentional? Or is there a trick, to allow focus modes to be triggered with CIQ apps?

How do you get access to the Activity API? I have had no response from the form...

DudeMarr — Mon, 04 May 2026 14:13:20 GMT

I apologize if this is the wrong forum, but I could not find a general Developer forum for API requests.

I submitted a Garmin Connect Developer Program access request ofor RunNerd (runnerd.ai), an AI-powered running coach platform. I'm now expanding to beta and have a queue of Garmin users waiting — but Garmin data routed through Apple Health loses critical metrics (cadence, elevation fidelity, split detail), which I need the Activity API to resolve.

Two issues:

I haven't received any response since the original submission, and follow-up emails have gone unanswered.
The Connect Developer Program access form at www.garmin.com/.../ is currently showing "under construction," so I can't resubmit or update my application.

Could you confirm the status of ticket or provide a working channel to update or resubmit? Happy to jump on the integration call referenced in the program FAQ.

Thanks, Aaron

accent color not applied after Apply (Fenix 8 47mm)

9748102 — Mon, 04 May 2026 07:48:44 GMT

Hi,

I'm building a watchface for Fenix 8 47mm using Toybox.Application.WatchFaceConfig and I have a problem I can't figure out.

When I open the on-device watchface editor and scroll through the accent colors, the watchface repaints in real time, so the wiring is fine.

But when I press Apply and exit the editor, the watchface goes back to the default color. The accent I picked is not applied. If I open the editor again, it doesn't remember my selection either.

I've tried:

A clean copy of the SDK 9.1.0 "Watch Face with Settings" sample, brand new UUID, only accentColors in watchface-config.
Sideload via OpenMTP and also installed officially from the Connect IQ Store as Beta.
Replicating the App / Delegate / View pattern from another watchface I have that does persist accent correctly.
minApiLevel="5.2.0", <iq:language>eng</iq:language>, no extra permissions.

Same result every time: accent works inside the editor, but is not applied after Apply.

The strange part: I have another published watchface where the same code persists fine. Same device, same developer account. I can't find the structural difference.

Has anyone seen this? Is there something about the app identity or the Store namespace that changes whether a freshly published watchface gets its accent persisted?

Any pointer would help.

Thanks!

Published app doesn't update or install on some devices

MobileDriveway — Sun, 03 May 2026 02:21:08 GMT

Issue is resolved - see details here:

Published app doesn't update or install on some devices

I started getting a lot of reports that my "Universal App" doesn't update for some users. If they delete it, they can't install it back. The app doesn't use Garmin Pay.

I updated the app with the most recent SDK and published an update - it was accepted without any issues. However, when I tried updating it on my watches, one of the watches had exactly the same issue as other users. On Fenix 8 AMOLED, the update was queued forever. When I uninstalled, I couldn't install it back - it would say "installing", then briefly "settings", then back to "install". In log file I found a bunch of these:

---
Error: 'Signature check failed on file: DB1A9BFA'
Time: 2026-05-03T01:40:38Z
Part-Number: 006-B4536-00
Firmware-Version: '21.39'
Language-Code: eng

What is weird, is that this app updated on my other watch Enduro 3 without any problems. Same user account.

Any ideas?

TotalTime datafield

2132550 — Sat, 02 May 2026 09:00:00 GMT

Hello,

I'm a beginner and completely lost.
I have an Enduro 3 and I want to display the total time during an activity in HH:MM:ss format. Currently, this time is only displayed in h:MM:SS format; the hours are too small for me to see.

I've installed SDK Manager (SDK9.0), Visual Studio Code, and Monkey C. I've created a new project called "TotalTime." But I don't know how to code it to do what I want.
Can anyone help me?

Thanks
