does anyone who has the applied ballistics app know if there is a way to sign into your online profile from a computer. There is an option to sync back and forth from the device to the internet so I assume you can access it from a computer? Also, according to applied ballistics website, they have custom curves for all of the bullets outlined in Litz's book, however when i select the .224 Berger 75gr. VLD, I am redirected to the google store and then informed that it is not available, Is this the case or do I need tech support? Thanks for your help!
