I don't like habit streaks. They backfire as soon as the inevitable happens and I miss a day.
To solve that, I created a "Momentum" system that lets you bounce back and recover after a broken streak. I made an app for it (called Polar Habits,) but I've also created this FREE template with Google Sheets, implementing the same system (albeit more basic.)
Enjoy!
