  • Harassed me every time I start it to turn Bluetooth on

    By captainamer
    App really wants Bluetooth in but I have no Bluetooth devices for it to connect to so this needs to not beg me to turn it on Other than that love it First round hits at 400 & 515yards because of this app
  • Great ballistic app

    By luisap22
    I down loaded several ballistic apps after reading an article on the best apps available. I found this one very easy to use and the retical function is a big bonus. You can use cartridge information included in the app or you can input everything your self. Definitely give this one a try
  • Great App.

  • Super Intuitive Ballistic Ap; My Favorite!

    By Willrite
    This has been my favorite Ballistic app for a long time. Has some great features like really easy truing for velocity or bc. Also integrates with most of the wireless environmental data collection options out there. Everything can be backed up tot the cloud too. And Strelok is the only bal Ap that gives a visualization of your holdovers using your actual reticle. Love it.
  • A must for long range shooting

    Great app. Super easy to use. Worth every penny.
  • Superb ballistic app

    By Bob-Boffice
    Have only just downloaded it and fiddled with it, haven't even taken to the range - fantastic app. Every time I wonder - "Does it do X?" I find it does exactly what I was looking for or expected. Pretty intuitive overall. Only thing that threw me off was selecting the rifle I want, would have expected that to be a primary menu item at the top instead of deeper in the main screen. Not a biggie now that I know. Very impressed with the ease of exporting the data. This will help me fine tune and learn in the field and then allow me to create customized data charts later on. The app had my common rifle, scope, and bullet info readily available to load up. Great job, highly recommend this to a new shooter or experienced shooter looking for an app to make field work simple. I look forward to having more fun at the range now.
  • Fantastic Service

    By Dbronc1
    I recently ordered a US Optics B25 with the MGR Reticle in Blue. I sent Igor a message and thought it may take a while. I am pleased but not surprised this guy delivers on his request. Great job and thanks
  • Great app! Just doesn't have my scope

    By Phs33track
    Really could use the vortex crossfire II 4x12x44. It's a hell of a scope and would really like to be able to use this app with it!
  • 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

    By side-burn
    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.
