Quick answer

The claim: habit trackers are mostly useless. Logging becomes a second habit, and one missed day wipes out the streak and the will to keep going. The research on missed days is good news.

What habit research found

In a 2010 study, people took a median of 66 days for a new daily behavior to feel automatic, ranging from 18 to 254 days. Missing a single day didn't meaningfully hurt the habit's progress (a 2010 study on habit formation).
