The C+ Calculator is a little application I personally developed for helping me in the Subway Surfers game.
Im a huge fan of the game and play it a lot. It always bugged me that I never know when Ill have enough keys and coins for upgrades or new characters.
Thats how this application came to life, to help me estimate when Ill have enough resources for my desired in game actions.
Im releasing it for free so you can benefit from it too. Enjoy :)
