Game Task Timer gives you a convenient place to keep track of your game cool downs and timers!
The full version of the app gives you unlimited (as many as your device has space!) timers to keep track of things like professions, cool downs, and so on. You can even use the app for things not related to games like when you took medicine. The app gives you an option of having a notification pop up when the timer is finished!
If you only need 10 timers at a time, I suggest using Game Task Timer Free available now on the App Store!
