I use Strelok Pro and like it. However, I think the ability to get it was shut down. Perhaps due to sanctions. The app works on my phone but I won't try to update it for fear of it going away.
I use AB which came on my SIG Kilo 2400, works excellent, been very happy with the whole setup(weather/ballistics on board the range finder)sweet tool thats simple to use and extremely effective...
Shooter App isn’t bad nor the Hornady. I use StrelokPro but as said above there’s fear it might get taken away. Igor posts a bear with me comment on his website every so often. My SIL is using the Sig range finder with their software and it’s pretty good. Just choose something with good reviews and take the time to learn it and ask questions.
