This app is amazing in my opinion, because you can email Igor, get an answer back quickly, and see changes within a week; I also use other iPhone mobile calculators with our Kestrel AB Elite like ABMobile, Shooter, BallisticsAE, Trasol, Bullet Flight, and several other mobile apps including the Kestrel Link app that comes with the Kestrel, however I find Strelok Pro to be more repeatable with the Kestrel’s wind call Bluetooth integration. We are able to consistently get on target with various distances from 278 to 1015 yards with a 308, 6.5, 30-06 and 5.56. Again my best reasons is app support (being able to email Igor) and see a long list of additions/fixes/enhancements and new features added every year versus the competitors apps that get a few updates a year if lucky or if they have to, because it stops working when Apple changes something. Igor’s app is priceless.

Dead on!!!

There is no better, more detailed Ballistic calculator out there. I'm glad I took my friend's advice and purchased it. The wealth of information in scopes alone is worth the price. To the developers... very nicely done! No glitches. No inaccuracies. Just a great program. I've talked 7 people in to purchasing the app. Every time I'm at the range, I do my very best to show off the app. I haven't had a single person try to tell me the one they were using was better in any way. Thanks for a good product I can trust!!



The perfect addition to the tools of the long range target shooter or any hunter. I use it with an $85 WeatherFlow weather meter and real-time shooting solutions appear. Choose your reticle, define your target and the proper adjustments are in your hand. MOA, Mil dot, inch adjustments or number of clicks are all right there.
If you don't want to think, just call up your reticle image and type of target, then make your scope look like the screen and squeeze 'til you hear bang.
Also an excellent way to play "What should I do if ...." scenarios.
