I bought this version because it supports Apple Watch but I went back to the free version. This one doesnt have options to create own glasses with their content like the free one does. The paid version has a simplified and standard reminder system with only one phrase. The free version updates you in its notifications how much you still have to drink to reach your goal and does this much more motivational than the paid version. I contacted the support desk twice and havent had a response in over a month. Bad bad bad...!!!!!!
