Gems Calculator for Clash Royale Guide

The Gems calculator application is a fan made helper application for Clash Royale.

It was developed because of my personal need of knowing how much time is left before I was able to make certain upgrades that required gems.

Instead of keep guessing and refreshing the game, Ive made this simple application that calculates how much you have to wait to get more gems in the game.

Im releasing it for free, so everyone can benefit from it. Enjoy!
