Love this, but...
This is the perfect app for measuring the days since you did something (like wiring quitting a behavior or trying to pick up frequency of a behavior), it keeps stats on how long it is each time and you can make notes about that occasion. One major gripe, it's too easy to accidently delete something with all the history by accidently swiping left instead of right, and no undo. Developer, PLEASE FIX THIS.
