What phone app will work with Arken scope
Strelok and Strelok Pro used to have the reticles in their program. That is the only ballistic app that I have seen that actually uses the Arken Optics reticles. What you can do though, is find a particular app that you like, and just find a reticle that closely resembles the Arken, and input your specific ballistic info into the program. It should work the same way for you.
