Reminds me of another app called as Bus Uncle. Overall, the concept is different than any other app that keep tracking your daily activities. Definitely, some may find the app is offensive, but yeah no more sugar coat.
Just a suggestion, I think having profanity will be more motivating and make the app fun to use ;)
I think many people have potentials to do more but due to useless habits and addictions, they are not able to put their 200%. This app is that 1st step!
Love the no bullshit, straightforward approach! Really what's needed for discipline.
