Love it! Reminds me of an app my brother and I built 10 years ago (time flies!). It's no longer on Google Play because of the maintenance burden of keeping it there, but here's a page with some screenshots: https://apkpure.com/spinach-motivation-lock-screen/com.tengu...

The idea was that if you're unlocking your screen, you should at least: (1) reinforce a mantra, or (2) force yourself to acknowledge you shouldn't be unlocking the phone.

Happy to share notes if you think that would be helpful.
