How it works
Spaced repetition
Each time you study a card it's scheduled further into the future. The better you know it, the less often you see it — so your time goes where it's needed most.
Study modes
Due today
Cards scheduled for today across all decks you’ve started — your daily review.
Study all
Any card in the current deck, due or not.
All cards
Every deck in your space at once.
Card status
New
Not studied yet.
Getting there
Making progress — keep going.
Got it
Well learned — comes back occasionally to stay fresh.
Keep trying
Needs more work — appears more frequently until it sticks.
Home screen
Each deck appears as a card on the home screen showing its name and how many cards are due. Tap a deck to expand it — you'll see Study, Manage deck, and Deck settings. Tap again to collapse.
Spaces & decks
Space
A subject area — Spanish, French, Music Theory. Up to 5 spaces.
Deck
A group of cards within a space — Verbs, Travel, Numbers.
Managing cards
Edit
Tap ✎ on any card in Manage to edit Side 1, Side 2, or the example sentence.
Move
While editing, use the deck selector to move a card to a different deck in the same space.
Archive
Archiving pauses something without losing any progress — works for individual cards, whole decks, and entire spaces. Restore any time and choose to pick up where you left off, or start afresh as if you'd never seen it.
Card Flash decks
Ready-made decks are available to add to your spaces. Browse them via + New deck → Card Flash decks. Spanish and French are available now — more languages coming soon. Our decks are labelled with (CF) so you can spot them easily. You can rename them any time in Deck settings.
Import & export
Export
Download any deck as a CSV file from Deck settings — useful for backup or taking your cards elsewhere.
Template
Need a blank file to fill in? Download a CSV template from the Import screen — it’ll have the right columns ready to go.
Import
Load cards from a CSV file when creating a new deck. Expected columns: Side 1, Side 2, Notes, More notes. Header row optional.
Themes
Themes change how the app looks — the colours, textures, and visual style. They don't affect your cards, decks, progress, or any of the learning mechanics. Age of Steam is the default theme — more themes are in development.
Space settings
Archiving hides this space and all its decks. All cards and progress are kept — restore any deck from the home screen any time.
Deleting permanently removes this space, every deck, and every card within it. We can't get any of it back for you. Consider exporting your decks first (coming soon).
About
Card Flash
Card Flash is built on a simple idea: learning a little every day adds up to a lot. It uses spaced repetition to help you remember things that matter — languages, facts, whatever you're working on.
Ready-made Spanish and French decks are included — more languages coming soon. You can build your own decks card by card, import from a spreadsheet, or export any deck as a CSV for backup.
No accounts, no subscriptions, no ads. Everything lives on your device — we don't collect, store, or sell your data.
