Review at the right moment, without paying for a usage cap.
MetraCards is a spaced-repetition flashcard app with automatically generated audio and unlimited decks. What competitors charge for is already included here.
Two things other apps charge for, free here.
Study as much as you want, no paywall mid-session
Create as many decks and cards as you need and review with no daily cap. The only limit is how many cards sync to the cloud. Studying itself never stops.
Pronunciation generated for every card, no plugin
Write the card and the audio is already there. You don't need an add-on, an API key or an extra subscription to hear the sentence, which is a paid feature in other apps.
Organise, answer, come back only to what's due.
Create decks and cards
Split by subject, topic or goal. Text, image and audio in the same card.
Answer and rate recall
See the front, pick a difficulty. The next interval adjusts itself.
Return only to what's due
The deck screen shows today's load and progress across new, in progress and mastered.
Same method. No add-ons, no setup.

Does MetraCards have usage limits?+
Not for studying. Create and review as many cards as you like. There is only a quota on how many cards sync to the server. Local study stays unlimited.
Is audio generated automatically?+
Yes. Pronunciation is generated as soon as you create the card, with no plugin, API key or paid plan.
What is spaced repetition?+
You review at growing intervals, always just before you forget. Long-term memory consolidates with less study time.
