Strelok and with out using it I like it the best out of all the calc apps I've researched . I've even down loaded a few others to my phone . The Strelok seems to work the best as far as ease of use , cost and amount of things it does . I love the feature that lets you change the magnification on your scope/reticle just by using the slide bar . Can't wait to see if it's accurate .
