Why do we make so many habit tracker app?

It's not an answer, nor self promotion. More kind of a reflection.

So many years ago I made a habit tracker.

And I didn't really check what already existed.

I still use it to this day and I think it's better than other apps (hey it's my opinion ok :p).

It was only after making the app that I noticed how crowded the market was.

I certainly don't regret making it, as it was fun and lead to different opportunities, but it's kind of interesting.

What compels us to making habit trackers? There isn't even a market for it.

It also kind of feels like procrastination: "Instead of doing the habit, I'll make a tracker to make sure I'll be doing the habit in the future!"
