I had the same exact idea (barring shit emojis). I'm so happy someone implemented this!
Some people with mild depressive episodes don't realize they have the power to break free and make themselves feel better by simply taking action. I imagine this kind of app might just be the thing to get them started in the right direction.
But it goes without saying: if you have any persistent issues, contact a health care professional.
I'm sorry but I have to ask; was this intentional?
