AquaQuest provides you with a fun and challenging way to stay healthy by helping you track your water consumption. You log your water, gain XP, level up and get new character classes, and achievements for number of days completed. But there is a catch, if you don’t drink and log your water each day you lose XP and can eventually die. You can play up to level 4 for free after which you must pay to unlock the premium version in order to keep questing.
