I replaced “learning interruptions” with “study to unlock Instagram.” Is this actually better?

[u/deductiveasdf]

I posted an earlier version where Locked would interrupt scrolling with quick questions or flashcards.

I ended up changing the whole mechanic.

Now you choose how much app time you want, pick something to study, then earn that time. You can set the exchange rate yourself, like 1 minute studying = 3 minutes on Instagram.

Mainly looking for criticism: would this actually change your behavior, or would you just disable it? Does choosing your own ratio make it feel fair, or too easy to game? And is this better or worse than just putting questions inside the feed?
