Zynlo

Zynlo is a spaced repetition app for people who already have something to learn.

You bring the material. Zynlo handles what happens after a card exists: it tests you in a way that produces real evidence, notices how you failed, fixes the gap while it is still fresh, checks the fix worked, and schedules the next encounter so the knowledge stays.

WHY IT IS DIFFERENT

Most flashcard apps show you a card, ask whether you knew it, and hide the schedule. You grade yourself, and the app believes you. Zynlo asks you to produce the answer, so what it learns about you is real, and it tells you plainly when a card is coming back.

BRING WHAT YOU ALREADY HAVE

Import from Anki, with your media and your review history.
Import from Mochi.
Import from Quizlet, through Quizlet's own copy option.
Import a CSV, TSV, JSON or Markdown file, including awkward ones full of commas and quotes.
Paste a prompt into any AI assistant, then import what it hands back.
Or write your own cards, with images, formatting and maths.

A STUDY LOOP WITH AN OPINION

Typed production instead of tap to reveal, once a card is ready for it.
New cards start gently and earn harder testing as you go.
Hints while you are thinking, not after you have given up.
A daily limit you choose, so a backlog never becomes a wall.
Cram as much as you like without disturbing your real schedule.
Undo a card you answered by accident.

SEE WHERE YOU ACTUALLY STAND

Which cards are slipping, and what to do about them today.
Confusions the app has genuinely observed, not guessed at.
Deck health, so a broken deck shows up before it wastes a month of your time.
Progress figures with stated definitions, not motivational numbers.

YOURS, AND PRIVATE

No account, and nothing to sign up for.
Your cards, your typed answers and your history stay on your device.
Works completely offline.
Export a full backup whenever you want, with your images inside it.
Anonymous usage statistics only, and you can switch them off in the app.

Zynlo is built for the part nobody else takes seriously: making sure that in six months you can still retrieve what you learned today.
