As a current gamer who takes pride in keeping fit, fitocracy keeps me motivated through quests and levelling up :) I hope there will be a search feature for the quests soon, and a way to tag some Id like to look at as a quick reference. It can be time consuming scrolling through all of them to find what I want to work at next. Overall, the app is incredible and fun to use though!
