Your decks arrive intact.
Repple replays your whole review log through FSRS. Nothing resets to day one.
What carries over.
Review history
Intervals, lapses, due dates. Suspended cards stay suspended.
Nested decks
Parent::Child structure, the way you left it.
Cloze and math
Each blank keeps its own schedule. LaTeX renders natively.

They come along, right where they were.
Same scheduler, fewer settings.
Repple runs FSRS, the same algorithm behind modern Anki, and fits its parameters to your review history. Reviews have two buttons, Again and Good — a misused Hard skews FSRS, so Repple leaves it out.
Where each one wins.
Anki is excellent software. The honest comparison:
| Repple | Anki | |
|---|---|---|
| FSRS scheduling | optimized from your reviews | every parameter exposed |
| Works out of the box | import and study | powerful once configured |
| Modern interface | utilitarian | |
| Document reader | highlight a PDF into cards | |
| Drafts cards for you | from your PDFs and readings | you write every card |
| Fully offline | web app today | |
| Mobile support | free on the web, app on the way | $25 on iOS |
| Add-ons | two decades of them | |
| Custom note types | templates, cloze, image occlusion | anything you can template |
If your workflow leans on add-ons or fully offline study, keep Anki — it does those better. Your decks can move either way: Repple exports back to .apkg, review log included.
FAQ
Does importing keep my review history?
Yes. Repple reads your Anki review log and replays every review through FSRS, so each card keeps its stability, due date, and lapses. Suspended cards stay suspended. Prefer a clean slate? Toggle history off and everything imports as new.
How should I export from Anki?
Export your deck as an .apkg with scheduling included and "Support older Anki versions" checked. Repple reads both the legacy and current formats, up to 250 MB per file.
What happens to my note types?
They flatten: every card imports as front and back, with cloze deletions preserved as cloze. A note that produced several cards — a reverse, say — imports as separate cards, each keeping its own schedule. Custom templates and styling don't carry over.
Does Repple actually use FSRS?
Yes — the same open-source algorithm behind modern Anki's scheduler. Repple also fits the parameters to your own review history, the way Anki's optimizer does.
Why only two answer buttons?
Because FSRS doesn't need four. A misused Hard is the most common way to distort a schedule, so Repple keeps it to Again and Good.
Is Repple free?
The core is free and unlimited: cards, decks, reviews, Anki import and export. Pro adds the document features, like generating cards from PDFs.
Can I go back to Anki?
Anytime. Export your decks as .apkg — cards, media, schedule, and review log included — and Anki picks up where Repple left off. No lock-in.
