This app is 110℅ legit earning app. It gives you free litecoins based on time complexity. On every 3rd minute, I got like 0.0008 every 2 minutes although it can depen on your phone specs... you will get free LTC even without any type of mining.
Just searah for FreeLite in your app store. Or just go here:
