The 4 tendencies when it comes to habit formation:

They're less about distilling your life into a series of data points and more about becoming your ideal self: If you use their app, you too can become a person who practices good habits. You can become someone who exercises and meditates every day and always drinks eight glasses of water.

Habit-formation apps are aspirational tools

Habit apps can work, but only if you actively monitor the data from the app each day and use it to analyze how you can change:  if you actually use the device and take its data and turn that data into knowledge, then it can actually improve your odds of changing.

When habit apps work

<ul><li>Many rely on a “streak” feature: they track how many consecutive days you’ve completed the habit;</li><li>Other apps offer accountability features to pressure you into completing your goal; </li><li>Some apps turn habit formation into a game: The app rewards users who complete their habits with badges and other virtual incentives.</li></ul>

Habit apps use the psychology of habit formation

“There is not an app that gives you some magical ability to change. The way that you change is you spend the time necessary to look at the change you want to accomplish, to try and figure out each day why you’re getting closer or farther away from it, to give yourself rewards in order to encourage that habit to thrive, and then to actually commit to it and to make that data into actual knowledge about why you behave the way that you do.” - Charles Duhigg

Maybe a couple of mornings a week, I manage to be the person I most want to be: I rise when my alarm goes off. I go to the gym for a 6:30 spin class. I meditate. I take my vitamins. I make my bed and pack a lunch to take to work.
