Based on the numerical solution of modified point mass trajectory equations.The main features are:
- Solves modified point mass trajectory equations with an efficient integration method.
- No simplifying assumptions for best accuracy (doesn't resort to the usual flat fire assumption)
- All data organized into savable profiles
- Support for multiple ballistic coefficients at specified velocities
- Atmospheric corrections: support Army Standard Metro (ASM) and ICAO standard atmosphere models
- Support variable wind profile between shooter and target
- Includes Coriolis drift effect (Automatic latitude and azimuth, using GPS and sensors)
- Includes Spin Drift effect (Gyroscopic drift)
- Includes Aerodynamic jump effect
- Displays hold-over in reticle view
- Computes sight clicks adjustment for changing conditions (bullet, target distance, wind, ...)
- Computation of customizable drop tables
- Ballistic calibration (truing): auto adjust BC or muzzle velocity from velocity and/or drop measurements
- Possible to export results as .png images or .csv files

I have used this app for several years now and can say it is accurate and simple to use. It has shown to be spot on at different altitudes, temperatures, humidity and all the other variables you are able to input. The bullet data base is large though not large enough as their are always new bullets coming out which are not covered but are able to be duplicated. This app simply works and is good value. Thank you Xavier.

Excellent app with dang near every feature a shooter could need it want .... But not QUITE as quick to use as StrelokPro....

Ada. B. Sep 26, 2021     

The free apps give you more options and are easier to use. Save your 8$.

Tho. R. Jul 14, 2021     

Worthless. Not flexible enough for the basics. Designed for sniper wannabes.

A. G. u. Oct 28, 2018     

This app works great for finding bullet drop and corrections.

B. S. Jan 31, 2020     

This app works great, but unfortunately in the ammo database is missing ammo: Norma Bondstrike Extreme .308 Winchester Norma TIPSTRIKE .308 Winchester Could you send a database?

All. D. S. J. Mar 3, 2019     

works well with correct input

Chu. B. Dec 30, 2018     

Great tool! Highly recommend!

A. G. u. Aug 22, 2020     

Needs to be updated

Geo. S. Apr 25, 2019     

can you please add Vixen scopes

A. G. u. Jul 14, 2018     

Great application. Accurate solutions. Waiting for it to import more than wind from my weather station, but that would just be icing on a great cake.

RS. S. Jun 28, 2019     

outdated and developer is unresponsive, pretty useless if it's not being maintained.

G. F. Nov 15, 2018     

Without some major updates this apps is pretty much useless.

Mah. S. Jul 7, 2019     

Amazing app has very strong reticle data base and great Ballistic solver Highly recommended

Bre. S. Feb 2, 2018     

Works well used it out to 2000 yards

Jer. W. Feb 6, 2018     

Can you put some 30-06 Hornady 165gr SST under the loads category

Gra. H. Sep 10, 2017     

Could be one of the best but it only displays path (drop) in in, moa, mil or clicks and not IPHY. Not much point is giving option to enter scopes with IPHY turret but not be able to display path (drop) in IPHY as well. Clicks is absolutely useless, who wants to count 94 clicks when you need to dial in 23.5 IPHY!

Dou. D. Aug 15, 2017     

He's back, and updating the app. Thank you kindly, sir. It's a drag when you switch scopes to one that isn't in the app. Thanks for the update.

Chr. J. Aug 5, 2017     

This is exactly what I was looking for. I really appreciate the wide selection of reticules. I look forward to many more updates. After spending tons of money on ballistic software I finally found one and its absolutely affordable!

jas. m. May 27, 2017     

Please add support for .300 Blackout

Bil. a. D. W. Jul 12, 2017     

Perfect... And I've been reloading and shooting for over 30 years

Rob. F. Apr 20, 2017     

Seems accurate so far. I'm confused as to what a "Min. Vel. M." is, so more info on the velocity algorithm would be nice. Additionally, the scope reticle is the only thing preventing me from entering all my own data. UPDATE April 2017: I still use this app and LOVE it! Thank you!

Phi. D. Jan 28, 2017     

I sent an email on Jan. 16 asking this question and have not got a reply yet. When I am on the Adjustment For Current Condition page I can not get the number of clicks to show up in the Clicks Column. What do I not have turned on?

Ale. S. Jan 15, 2017     

Don't have my vortex scope or hornady 223 ammo that I use

Wal. T. J. Dec 2, 2016     

User friendly with a well designed interface. The contents of application will satisfy 99% of all shooter's. Very well done.

A. G. u. Nov 4, 2016     

Seems to do what needs be done. Didn't have one of my reticles but hopefully it will get added soon.
