  • What an App......

    By Rickster1001
    I have this on my IPhone 6. All of my rifles have been inputted, caliber are loaded. Needless to say, if you are capable of doing your part, this helps remove a whole sh-t of guessing.
  • The best app in the market

    Everything you need is in the app. Very intuitive. Using it about 2 years and every time getting amazing results. Recently I contacted the developer regarding my new Nightforce SHV 5-20x56 data about which I thought missing from the list. It was not the case, I had to be just more attentive. As I said everything you need is there. And what a great way of treating the costumers. Thank you for the nice customer service. Thank you for the app.

    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.

    The MV does not seem to be correct. I set it at 2940 @ 60 deg. F then the setting says 2981 @ 75deg F.
  • Top notch external ballistics app

    By flyingtexan86
    StrelokPro has one of the best UI out of all the ballistics apps I’ve used. App is stable and doesn’t ever crash on my iPhone 6S+, iPad Air 2 and iPhone 8 Plus. I’ve also used StrelokPro on Android too. The only big thing missing from StrelokPro is there’s no trajectory graphs.
  • Only 1 option

    By Vahaoqbwhsjsownq
    For the price of this app, there should be different scope and ammo options. If it doesn't have the scope I'm using, then why bother getting the app?
  • Outstanding!

    By Moznyati
    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.
  • Great App
