Watch App: TruFlite Ballistics

It would be great to be able to enter many more profiles as most shooters have several firearms and use a combination of ammo in each (3 profiles is not enough for one rifle, never mind multiple!).

Ideally a relationship that allows multiple bullets per rifle\scope combo. In other words you could have a few rifles with different barrel twist direction and inches per turn and different scope height. Then you may be shooting different grain bullets for different purposes with each rifle.

Once captured, the rifle\scope details and ammo details largely remain static but there is some info such as temperature, pressure, humidity and scope angle to target, that changes every shoot.

So some way to capture the following on the phone, to sync profiles on the watch, would be great!

1. Rifle calibre, barrel twist info and scope height (for multiple rifles)

3. Bullet info (for multiple bullets)

4. Multiple Profile creations based on combining a particular bullet with a particular rifle of the same calibre

On the watch itself, the ability to select a particular profile on the day and capture info relevant to that shoot, such as temperature, pressure, humidity and scope angle to target.

Hello Jeff,

great app, thank you !

would be possible to put the wind direction on “auto” just as azimuth ? As well “slope”, not sure however that garmin watches have a tilt sensor. 

I’d second the request for more profiles. 
and the capability to duplicate rifle parametersxlike scope height while tweaking MV and BC.

this app will be complementary to using a range card with 50m steps as I have set watch the step distance to 10 which is specially useful for longer range 22LR.

trajectory from this app matches my phone app so provided you input all correctly it is accurate.  

Version 2.3.8 (Dec 2023)

New Device Support:

Descent Mk3 43mm / MK3i 43mm, Descent Mk3i 51mm
Fenix 7 Pro - Solar, Fenix 7x Pro - Solar
Venu 3, Venu 3s
Vivoactive 5

Instinct 2x Solar - Beta Version, Not fully functional.  Display Issues.  But should now fit in memory of device.  Feedback appreciated.  If goes well more Instinct 2 devices coming.

Version 2.4.0 (Dec 2023) Release Notes

Major Features:
Instinct 2 Device support. Rewritten version that fits in memory constraints. Layout specific to Instinct Inset. Looking for feedback.

New Devices:
ForeRunner 745
Forerunner 965
Instinct 2, 2s
Instinct 2x Solar
Instinct Crossover
Descent G1, G1 Solar

RangeCard:
Menu on RangeCard access via standard menu operation from RangeCard screen.
Option to set increment to single line or full page at a time.
New Layout on some devices for be better font/sizing.

Bug Fixes:
Clicks - "Display As Clicks" only applies to angles; mils or moa. (Ignore "Display As Clicks" if set to "inches" or "cm")
Latitude - on startup, after a device restart/reset, an invalid latitude value would be given until new GPS signal acquired

I just wanted to add a quick thank you note after finding this app! I like the simplicity of it - seems much quicker than fumbling with a phone app with gloves and/or potentially wet/cold fingers.

The only thing that got me at first was that the range was going up/down in meters, until I found the setting to change it to make bigger jumps, so it doesn't take ages to go from 300 to 700m. A useful addition would be if it always showed the units next to each measurement - just removing the need to think or remember.

Great job with the app!

Any chance for adding in the future releases:

1. G8 function (similar like in Strelok Pro), now is only G1 and G7

2. Twist rate input for more accurate calculations requiring barrel twist

3. Target/Range card for PRS. Define number of targets at certain distance and to view on the card: Target Number | Distance | Elevation correction | Windage correction. Would be very usefull in PRS competition with multiple targets and different distances and requirement to shoot in precise sequence. Quick look on the watch to remind sequence and corrections. PRS card would use current set profile and settings.

Thanks and all the best!

1.  There are certain devices that are EXTEMELY memory limited.  I am now going to leave those devices at the current version going forward, v2.4.  This will allow me to add features to other/newer devices with a lot more memory going forward.  So I can reconsider this and other features.

2.  Twist rate (and a bunch of other bullet attributes) is used for calculating bullet stability.   Bullet stability feeds into spin drift and aerodynamic jump.   TruFlite assumes your bullet is well stabilized otherwise you wouldn't be shooting it long range.   Therefore I dont have to ask for these additional bullet features, just the twist direction.   This was a trade off I made since this is a watch interface and I tried to limit the inputs.  This introduces little to no error in most cases.

3.  This is one of the most commonly requested features at this time.   Now that I am freezing limited memory devices I should have enough space to work on this feature again.

thanks
jeff

2.5.0 (Oct 2024) Release Notes

New Devices:  Enduro 3, Fenix 8 43mm/47mm, Fenix 8 Solar 47mm/51mm, Fenix E

Features:  Additional Profiles, now 5 instead of 3

Notes:  Some devices, such as the Instinct2 series, have extreme limits on the amount of memory a running app can use.  Those devices will stay at version 2.4 so that other devices can move forward with new features, such as more profiles.
