Super easy and simple got it to match up with my gun within minutes of playing with the app!

Loved the app when I had my Fenix 5x. Any chance you can make it compatible for the Forerunner 955??? Thanks

Check out version 2.3.5. Support for a couple new devices: ForeRunner 955, Venu Sq 2, MARQ Gen2. Let me know how it goes. thanks jeff

September 18, 2022 | Version 2.3.4

Bought this to save using my phone out in the field. I contacted Jeff with a data issue. He has been great at sorting it out and really quick too. The only upgrade I would say would that be easier for me - have the wind angle open a screen with an arrow so you can drag it to direction rather than a number input. Overall it's great to have a drop chart for all my rifles on my epix. Better than a phone in the rain.

July 22, 2022 | Version 2.3.4

The app is awesome as long as you know how to true your data. Gave it 4 stars due to the limit if only 3 ballistic profiles.

Mads Brøndum
July 6, 2022 | Version 2.3.4

A really cool app, however, would be nice if but could see wind in meters per. second and the shot length in meters

It can. All values can be set to either english or metric units. On the device go to the main menu, then select "Units". You can set distance to yards or meters and you can set wind speed to mph, kph, or mps. If using the Connect IQ Settings App on your phone scroll to the bottom to the "UNITS" section.

Sam Hinds

Love the app, very intuitive. Only improvement would be to allow more profiles. Between 5 and 10 would be perfect.

March 21, 2022 | Version 2.2.0

Great app. It should be great if we could have MRAD as other units like with MOA. Some rifles are using MRAD and not only MOA. PRO version is interresting but too expansive.

TruFlite supports Milliradians. When setting elevation and windage units for a profile you can pick [in, cm, moa, mils]. Thanks jeff

I have just recently gotten into long range shooting and this app covers everything I need. The other guys on my team are all talking about getting a garmin now because of the easy results and accuracy while in the field. Amazing app and I would definitely recommend!

Nathan Pedroza
January 18, 2022 | Version 2.1.1

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

January 17, 2022 | Version 2.1.1

breathe and shoot. 10 +

Jack Fries
January 14, 2022 | Version 2.1.1

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.

Después de introducir los datos balísticos , no me da ningún dato de corrección

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

Brad Collingwood
October 17, 2021 | Version 2.0.8

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

October 11, 2021 | Version 2.0.8

Excellent app!

Clay Moyers
October 8, 2021 | Version 2.0.8

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.

September 24, 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.

August 14, 2021 | Version 1.6.2

Is similar than Ballistic app of delta tactix?

Sammy Smallwood
August 10, 2021 | Version 1.6.1

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

Igor Timmermans
August 2, 2021 | Version 1.6.0

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

OJ Innaglass
May 17, 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.

Mario Velloso
March 4, 2021 | Version 1.6.0

Where do I input the bullet weight?

Developer Reply
March 6, 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.

Johan Blohm
February 23, 2021 | Version 1.6.0

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

Developer Reply
February 23, 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

January 22, 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.
