Great app to increase your productivity

This app is ideal for those who always loose focus, or feel tired after long time studying. It efficiently allocate your energy and make you concentrate.
A problem is that you have to purchase both ios and mac version if you want to use it on iPhone and Mac, but the functions are all the same. It’s a waste of money if youve already bought the ios version and buy this again.
