Time Summoner Spells quickly and easily while playing with just one single tap on the screen.

In loading screen you'll have enough time to set up everything - the app starts with the most common Summoner Spells for each role. (Top: Flash / TP - Jgl: Flash / Smite - Mid: Flash / Ignite - ADC: Flash / Heal - Sup: Flash / Exhaust) - but you can change the individual Summoner Spells quickly via a dropdown menu.

You will have the option to click "Cosmic" in case someone runs Cosmic Insight and gets 5% reduced Summoner Spells, or "Boots" in case someone buys "Ionian Boots of Lucidity" and gets 10% reduced Summoner Spells.
The app calculates the correct cooldowns accordinglyly.

Spell cooldowns by clicking the drop-down on the right hand side. I added this option because you can not always tap your smartphone screen instantly while plaiyng. This way you'll always have the correct timers, or even lower timers. But better safe than sorry !!

Check it out, give it a try. Please give me improvement suggestions and leave a rating. :)
