Has become useless to me... – Applied Ballistics Review

Using this app from iPhone x.. I cannot even use this app, because after putting all my info into the App, i get impossible firing solutions. If i could get my money back i would...only way to get it to work is to delete and re install, then it works for a while. I don't have this prob with my other ballistics app.
