Reading the ranking
The score weighs how easily the habit stuck, how the product felt day to day, how it handled your data, and what you get for the money. A cheaper pick does not automatically beat a costly one: Levels leads on the insight it gave us, not on price, and Cronometer wins value at a fraction of the cost. Each review breaks the score down point by point on a one-to-ten scale.
