TruFlite Ballistic Calculator


TruFlite is an exterior ballistics program for long range shooting. It contains a highly accurate, yet stand alone ballistics engine that is extremely fast. Designed to not rely on connecting with a phone for data input or for calculations.</p><p></p><p>Free Version: TruFlite is still free. The basic (free) version includes all the features that previous versions of TruFlite had. Unfortunately if an app charges at all, even for an upgrade, the Garmin store will tag it as "Payment Required". No payment is required to use basic TruFlite and all its features.</p>

10/10. This app was nailed. Great for bench shooters and hunters. Easy to use and a great reference when under the gun!

17 January 2022 | Version 2.1.1

breathe and shoot. 10 +

Accurate to within 1/10 MRAD for a 308 Win at 825 yards. Great product! Get this app and consider upgrading to pro to support this developer. It is just as accurate as AB for $1000 less (compared to buying the Tactix Delta AB) if you enter your data correctly. If it gives you a solution that isn’t accurate, double check your parameter settings. Garbage in = garbage out.

Can you use the "Contact Developer" link and send me what data you used. thanks jeff

Great App, well worth the $20 to upgrade to Pro. The upgrade process was extremely easy. Highly recommend.

11 October 2021 | Version 2.0.8

Excellent app!

Absolutely rocks! Send to give me the same door as AB. Love the fact I can turn off the aero jump and spin drift. Makes it easy to come up with a pure solution.

24 September 2021 | Version 2.0.8

Firstly WOW... This is a must have app if you are a shooter.. I am operating with long rifles often and this little app is blood amazing.. Just works and works very well indeed and in the tempe and you have a great and near perfect ballistic solution app.. Saves time and kit... Add to this the Dev is outstanding and very responsive.. You couldn't ask for more from both the app and dev... just outstanding. Download and enjoy you will be happy you did..... If I could give more stars I would....

Love it. It works great when shooting long distances.

14 August 2021 | Version 1.6.2

Is similar than Ballistic app of delta tactix?

Great app. Very useful for getting quick Dope to put rounds on target. User friendly.

Awesome App! I would pay happily for the feature to store multiple calibers.

17 May 2021 | Version 1.6.0

App is quick to setup, easy to use. Would pay for more detailed settings to take into account spindrift etc and maybe the option for 2-3 different loads. Only other setting I would like is zero offset.

Where do I input the bullet weight?

Developer Reply
6 March 2021, jrjackson

Bullet weight (and other bullet characteristics) is not needed to calculate a trajectory. The BC of the bullet is all you need. Other bullet characteristics (like bullet weight) are needed to calculate things like stability, spin drift, aero jump, energy, momentum, which TruFlite currently doesn't do. Tried to keep it as simple as possible with as few inputs required since it is a watch interface.

Any chance to see metric units and mils any time soon? Not useful to me without it.

Developer Reply
23 February 2021, jrjackson

On the watch/device you can select mils or cm for elevation and windage and each variable can be put into metric or english units independently. If you go to the menu and select Units you can change english/metric for each individual variable; range/zero, wind speed, altitude, pressure, temperature, muzzle velocity and sight height.

Awesome app use it hunting with my air rifle thanks

22 January 2021 | Version 1.6.0

Great app, I got accurate results with the G7 model. It would be nice to have the option to load multiple gun/ammo presets though.

6 January 2021 | Version 1.6.0

great app that works really well and can be used in long range shooting. it would be great if you could create multiple profiles for different weapons. At the moment it is only possible to create a profile. this should be updated if possible

21 December 2020 | Version 1.6.0

So far I really like this app. I only wish that I could make a adjustments to the windage from my watch. This would be very handy in hunting situations where you may have to set up and move a few different times before taking a shot

i like the app. the calculator works good. unfortunately i've some issue with the phone configuration. what i write in the phone arrives wrong in the watch. maybe it is due to the metric settings. i have to set directly into the watch, but it is not so fast. i miss also the profiles saving options.. i would pay for an app with the feature i want

Developer Reply
5 December 2020, jrjackson

Currently metric is not supported via the Garmin Connect IQ App. So if you are inputting values that way unfortunately for now you have to put in Imperial/English values. thanks jeff

Works very well, very simple to use and out put is true and comparable to my phone ballistic app. Checked and correct all the way to 1600yards :) Only downside is wind direction, be great if was able to input in at same place as wind speed. 12hr clock format would be ideal and be able to be squeezed in I’m sure.

Loftus Stanford
1 June 2020 | Version 1.5.1

really like this works spot on when comparing it to my sig saur and ziess calculators. would really like to be able to have 2 bullet profiles saved at once so I don't have to enter data every time I shoot with a different gun. cheers

Seems to be very accurate with an excellent interface. Looking forward to having a crack at the range.
