Measure Habit Streaks as the number of days since the streak started
Currently, when a habit is not scheduled for every day, its streak length is counted by the number of times the habit was tracked.
For example, if a client performs a habit scheduled 3 days/week (e.g. Monday, Wednesday, and Friday), after two weeks the streak is displayed as 6 Days long in Trainerize. An everyday habit will have a streak length of 14 Days after the same amount of time.
This difference means that it will take a lot longer for the 3-day/week habit to build a Streak with significant psychological weight.
It would be ideal if streaks for both types of scheduled habits were measured the same way. So that after two weeks, both the everyday and the MWF habit reached a streak of 14 Days. That is how streaks are calculated in other popular habit-tracking apps.
