You can now create your own cheat sheets for waiting times on gathering pokeballs and coins. Why is this useful? Instead of going to a location and running out of balls, you can now plan ahead and know in how much time youll have the required balls to catch the pokemon. So you can go out only when you can catch him and not make an extra trip just to find out you dont have enough balls.
This little cheat to plan ahead our moves made our internal team play the game more efficiently!
Update: Changed the name so it doesnt imply the app is a cheat for Pokemon Go that interferes in an unauthorized manner with servers, api, etc.
