JLPT Study That Happens Before You Scroll

Earn locks Instagram, TikTok, and the games on your phone until you answer a few Japanese questions. Fifteen minutes of scrolling costs you a handful of kanji.

No deck to remember to open, no review session to schedule. The practice is already standing in the doorway.

Questions about studying Japanese with Earn

How is this different from a flashcard app?
A flashcard app waits for you to open it. That works until the week you are busy, and a JLPT deck that goes untouched for ten days is the usual reason people sit the test underprepared. Earn puts the review in front of the apps you open anyway, so the streak does not depend on you remembering.
How many questions do I have to answer to unlock my apps?
You pick how much time you are unlocking — 15, 30, or 45 minutes — and the number of questions scales with it. A short unlock is a handful of items, which is small enough that you do it instead of putting the phone down and forgetting.
Can Earn get me through the JLPT on its own?
No, and it is not trying to. Reading passages and listening sections need long, focused sessions that a lock screen cannot give you. What Earn does is keep kanji and vocabulary from decaying in the weeks between those sessions, which is the part most self-studiers lose.
Which apps can Earn block?
Anything on your iPhone: social apps, games, streaming, a specific browser. You choose the list, and Earn keeps it closed until you clear a challenge.
I am learning Japanese but not sitting the JLPT. Does that matter?
Not at all. The packs follow the vocabulary and kanji you are working through, whether that is for a test in December or a class next semester.
Can I use Earn for something other than Japanese?
Yes. The same unlock mechanism runs on whichever packs you turn on, including SAT and ACT practice. Switch packs whenever what you are studying changes.
