Description
Block social media until you can prove you've learned something.
F2S intercepts your social media habit and turns it into a study session. When you open Instagram, TikTok, or any app you choose, F2S steps in with a quiz. Answer correctly by explaining concepts in your own words, and earn your scroll time. Fail, and try again.
It's the Feynman Technique meets screen time control.

When you try to open a blocked app, F2S intervenes
Answer 3 voice-based questions by explaining concepts out loud

Track your streak, daily stats, and average score
WHY VOICE?
Typing an answer is easy to fake. Speaking forces you to actually understand. The Feynman Technique says: if you can't explain it simply, you don't understand it. F2S puts that to the test every time you reach for social media.
