  • Great App

    By Jendjdnneb
    Been using this for the last few months out to 600 yards. It’s worked well on all my rifles and has a huge database of reticles. I would buy again in a heartbeat.
  • Best I’ve used

    I love the simplicity of the interface and how easy it is to tune my dope values. I’ve tried and purchased many, but this is my favorite.
  • Great App for LRS

    Takes most of the guess work out of the equation.
  • 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

    By Ubiq
    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 has much more flexibility over the others. Love it and use it regularly.

  • Own every iPhone ballistics 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.
