i think people that voted for strelok got it because its free, and theyve never had another app. for moderate ranges (600ish and in) you'll likely not notice how subpar it is. but once you play with something like shooter, or even step up into applied balistics, you'll realize how much strelok leaves to be desired. I personally use BallistARC due to its integration with my weatherflo meter. but i hear Shooter now has the option as well. Shooter is incredibly user friendly, so that is liekly were i would go were i to start over. but BallistARC is spot on for me, and i have already payed for it. so thats where i am at.
