Your history comes with you
Import from Anki and your scheduling and review history arrive intact, per card. Export all of it, in plain formats, on any day you feel like it.
Interval Pro
Nothing you build here can be taken away from you
Your decks and their review history follow you to whatever you study on next, backed up as you work and yours to export.
What Pro does
Nothing riding on one good sync
Your work is backed up as you go and stays in step on every device you study on, with conflicts worked out instead of one side quietly winning.
Hours of card making down to minutes
Draft cards from what you are already reading, look over the changes the way you would a diff, and keep the ones worth keeping.
Nothing to bolt on that breaks next month
Heatmaps, image occlusion, cloze tooling and importers are part of Interval and ship with it, so an update cannot take one of them away.

Questions people ask
What happens if I stop paying?
Your cards, notes and review history stay yours and stay readable. Syncing pauses. Export stays open, so you can take everything with you the same day.
Do I have to rebuild my Anki decks?
No. Bring the .apkg across and your scheduling and review history come with it. Interval shows you what landed, per card, so you can check it yourself.
Is my streak safe if a sync goes wrong?
Your review history lives on your device as well as on the server, and both are backed up. A failed sync is something to retry, not something that costs you a year of work.
Can I study without an account?
Yes. Interval works signed out, on this device, with nothing held back. An account is what lets that work follow you to your phone and back.
