What they did
Took the existing app-blocker concept and added a cute digital pet brain that 'rots' (shows health, e.g. 97%) the more time is spent on distracting apps. Users set blocking rules per app and time; opening a blocked app (e.g. Instagram) triggers a short playful flow, such as a FaceTime call from the brain, adding just enough friction to change habits. Also shows screen-time stats by app and day. Born from the founder's own phone addiction.
What happened
The concept carried the launch and later growth to ~$400K/month; no direct measurement of the pet or friction flow.
- Stage
- Pre-launch (idea)
“It is a gamified screen time app. It is a play on the word brain rot, obviously, and has a cute digital pet brain that rots the more time that you spend on your brain rot apps.”
“In this case, I'm getting a FaceTime from my brain. I have to go through this little experience. It just adds a little bit of friction into using the app that is enough to get you to change your habits.”
“And of course, I could have downloaded an app blocker. I wasn't the first to come up with this concept. But I had this idea, what if a brain rots the more you brain rot?”
