Habit trackers are great when you pair them with a smart watch and automations. I use an app called Streaks, Apple Watch and Shortcuts. Streaks can pick up health data and in Shortcuts I’ve set it up so it increments a counter in Streaks to keep track of when I open Instagram or Twitter.
I’m not sure it gives me enough motivation to do something I don’t want to. But it does help me stay on track and not forget the things I want to do.
