I recently purchased the Shooter app for my iPhone and have had some issues getting the settings where I want them. I want to reorder my gun library, set spin drift to always on, change my wind direction to clock face rather than degrees, and default to the solution screen when I press "Calculate". I have seen online that these things can be done but i can't seem to find any of those functions. I bought this app after losing all my data from Strelok Pro after an update and due to some extra features in Shooter, but I'm considering using Strelok Pro again because there doesn't seem to be any developer support for Shooter which is pretty disappointing. Igor Borisov will answer your email for the Strelok Pro app withing 48hrs and received great support from him multiple times.
