League of Summoner Timers

Tired of enemies flashing your every engage or skillshot? ADC's heal baited you to your death? No more!
You played well in an ARAM and got S, but you unknowingly took a champion you already got a chest for? It does not have to happen again!
With the League of Timers app, you will be able to track your enemies' spells quickly and easily. Before the summoner spell is up, you will be notified by your phone that will tell you everything you need to know.
The League of Timers will gather all the information for the game you are currently playing, from the champions and their summoner spell to the runes they use, and based on this information a correct cooldown will be applied.
Teleport changed will be unleashed while it is still on cooldown? The correct time will be calculated. Amumu support has a hexflash? No problem, you can track both the hexflash and the flash cooldowns easily!
Before you even get into the game, a champion select takes place. You are feeling good and want to acquire a new chest, but don't know which champions you have gotten chest already?
Simply take a look at the Champ select tab and after selecting all champions you own, you will be able to filter out only those that will grant you a chest for playing good.
