I bought this app and it's really awesome! I tested it with silver coins and I couldn't fool it - the app is very easy to use and does exactly what is described. Now for the feature requests - Is it possible to add a "custom gold 9999 coin" feature? Is gold different somehow in this regard from silver? - If this is not possible, can I at least create custom coins manually (that is, if I intend to buy a specific coin many times, I can record its frequency so I can test future coins ) In either case, the app is already way more awesome than its competition - the iOS competitor app is paid AND has IAP's for all but a few coins - this app is a treasure in and of itself Thank you so much for making it!
