Is your habit tracking app really helping you building better habits?

Habit building is kind of tricky and serious researchers looked into it to understand how the brain works when building new habits. All the habit tracking apps are built for gamification, streaks, spreadsheets, constant nagging and input which contradicts the path for habit building. Behaviours that stick becomes habits .phone scrolling in bed before falling asleep is a habit (a bad one, but still a habit). If you are using any of the apps there that are actually helping you to build better habits would be great to hear your thoughts..
