Description by William Finney Written by the developer, not by AppBrain. Click to read.
Write a note and it joins your feed. Read it, tap Locked in, and it goes away — then comes back days later, around the time you'd start to forget. Notes you keep locking in return less and less often. Notes you wrote this morning come back soon.
Maths and science notation is written in LaTeX and rendered properly, so equations look like equations instead of a row of symbols. There's a live preview as you type, and a guide in the app if you've never written LaTeX before.
Use whatever subjects you like — GCSE Physics, Linear Algebra, Spanish verbs. Browse everything you've written in the Library, or let the feed decide what you see today.
Everything is stored on your phone. No account, no sign-up, no internet connection. Your notes are yours, they don't go anywhere, and the app works the same on the Underground as it does at home.
For anyone revising anything: school exams, university finals, professional qualifications, or a language you're trying not to lose.
No logins, no ads, no data collection — just revision
