Overall, I really like the idea behind the Life Of Discipline. The github-style chart is the best representation for habit tracking, imo. V2 brought a feature I lacked, which is the ability to add entries in the past.
To improve:
1. V2 email announcement leaked all users emails :(
2. There is no contact form on the app. Not on site, not on emails. As I'm not using Twitter, I have no way of contacting developers, except writing on Product Hunt.
