Repetra is a mobile flashcard app powered by FSRS-6. Swipe to grade, auto-generate cards with AI, and study 300+ ready-made decks, with native audio (available in 24 languages) for language cards, even your own. Built for deep, long-term retention.
Hey Product Hunt 👋
I'm the solo dev behind Repetra. I made Repetra because I was taking Russian classes and kept forgetting the vocabulary.
My teacher would throw a new word at me mid-conversation and it'd be gone three minutes later. I tried index cards and lost them within a week. Then I went through every flashcard app I could find, and none of them stuck.
The popular apps felt designed for short-term cramming rather than building real, long-term memory. On the flip side, the tools that actually used proper memory science felt so clunky and overwhelming that I just couldn't stick with them.
So I built the app I actually wanted: a smart repetition system, in something I'd look forward to opening every day.
Here's what it does:
- Smart scheduling: It runs on FSRS-6, the best spaced repetition algorithm I've found. It works out when you're about to forget a card and shows it to you right before you do.
- Swipe to grade: You just swipe to say how well you knew each card, and that shapes what you see next. The ones you struggle with come back more often, and the ones you've nailed show up less and less. It's fast enough that a review session feels more like scrolling than studying.
- Ready-made decks: There are 300+ to start with, so you're not building from scratch. They cover plenty of categories beyond languages, plus common-phrase decks in 8 languages and full A1 to C2 ladders in several languages.
- Native pronunciation: Repetra supports native audio in 24 languages, and it isn't limited to the ready-made decks. Any card in one of those 24 gets pronunciation, including the ones you add or generate yourself.
- AI card generation: Give it a topic, a link, or a document, and it turns it into flashcards for you.
- Mastery tracking: A card only counts as "mastered" once it's genuinely stuck, so you see your real progress.

Repetra is fully bootstrapped and still early, so I'd love your honest feedback. What feels off? What's missing? And if you're learning a language right now, tell me which one, because I'm taking requests for decks to build next.
I'll be around all day. Thanks so much for checking it out! 🚀
How does the AI auto-generation actually work for niche topics like medical pharmacology, and is there a way to import my existing Anki decks without losing the scheduling history?
@cetin11914 Hi Çetin! On AI generation you have 3 options: generate with a prompt, with a URL, or upload your own material (lecture slides, PDFs, notes, etc.). For niche topics, you can upload your own material and generate cards from it. But honestly any of them would work even if it's a niche topic. You can just specify what you need in the prompt.
An import is on the way, and I'm building it to bring your review history across so your scheduling picks up where you left off.
Since you asked, I put together a quick example just for this. I grabbed a small pharmacology PDF I found online and ran it through. Here's what the generated cards came out like:
