Good to know
Frequently asked
How does FlashKeepers decide when to show a card again?
It uses spaced repetition: each time you rate a card, the app estimates how long you will remember it and brings it back just before you would forget. The scheduler is FSRS-6, the open-source algorithm Anki also uses, so a card you know well comes back in weeks and a shaky one comes back tomorrow. A daily ceiling keeps a missed day from piling up.
Does the TV need the app?
No. Open flashkeepers.com in any TV browser and type the 5-letter code, or scan the QR from a phone. Nothing installs on the TV.
What happens if I fall behind on reviews?
Catch up spreads the overdue cards evenly over the next 3, 5 or 7 days, your choice. The daily ceiling still holds, so it never turns into a wall of review debt.
Are the AI cards checked?
Yes. Every AI draft carries a quoted source span and a status: supported, partial, or unsupported. Nothing is saved until you accept it in the tray.
Is FlashKeepers Pro a subscription?
No. Pro is a single one-time unlock, $14.99, yours for good.
Do I get AI credits with Pro?
Yes, 25 to start, once. After that you buy packs like everyone else, never a subscription.
Is progress tracking required?
No. The weekly ring, recall trend, cards learned and milestone awards are entirely optional, and the daily reminder stays off until you turn it on. One switch in Setup turns it all off.
Does it work offline?
Yes. Reviewing is local-first and works with no connection at all. Table mode, the shared TV view, needs an internet connection.
