    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

  • 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!!
  • Excellent App

    By Unobigdawg
    This is a great app with lots of information. As I am just getting into shooting it is also a great teaching aid. It is regularly updated. I recently bought an Aztec Emerald 5.5-25x50 scope the reticle was not in the list as this is a new scope and mfg, with that said this reticle was added today. When you go hunting make sure your phone is fully charged and buy an extra external battery.
  • Scopes

    I really need the Nikon prostaff 5 4.5x18x40 scope in this app. It works awesome other then that. Please add this scope ASAP
  • Best long-range ballistic Apps

    By Lionlake
    This Apps has a lot of features; yet it is very easy to use. And it has been updated frequently, which indicates that the developer is actively maintaining it. Highly recommended, it is definitely worth the money.
  • Clunky UI but Amazingly Useful!!

    By Jbeltran
    This is such a fantastic app for anyone looking to perfect their long distance shooting. With such a huge selection of reticles and settings to customize pretty much any aspect of the trajectory calculation, this app is a shooters best friend. My only complaint is that the UI can be a little confusing at times and the styling is rather basic, but given the vas amount of customization available, this is understandable.
