Your note
Photosynthesis takes place in chloroplasts. Oxygen is a by-product.
↓ Ellerni turns it into
Question
What is produced as a by-product of photosynthesis?
Back in 3 days. Then 6. Then less and less often.
How it works
01
Take a photo
A page of your notebook, the whiteboard, a page borrowed from a friend. Shoot several pages in a row — it doesn't stop after each one.
02
Get questions
From what is on YOUR page. Not from someone else's question bank, not from a textbook you do not own.
03
Review in time
A question comes back before you forget it — once a day, one notification. Not ten.
What makes it different
You answer in your own words
No four little boxes to click. You write what you remember, and we grade the meaning, not the spelling. If the engine gets it wrong, one tap says "I did know that" and the question counts as passed.
Intervals calculated, not guessed
A question returns after 3 days, then 6, then less and less often — and the morning after two misses in a row. This is not a to-do list; the spacing is built around how forgetting works.
Send a note to a friend
Page photos go to at most three named people and disappear from the server once downloaded — after 48 hours at the latest. Questions you can share by link; the photos never reach anyone by accident.
No ads, no harvesting
Accounts from 16. Photos stay with us for 30 days, because that is what reading and fixing them takes — then they delete themselves. Analytics without cookies, so there is not even a consent banner.

This is a test build
Ellerni works, but it is in beta: data can disappear without warning and features change from week to week. Installing from a file needs "unknown sources" enabled. Something broken? In the app: the Me tab → Report a problem. I read every report.
