UPLINK
Flashcards that find you.
Most flashcard apps wait for you to open them. UPLINK doesn't wait — it quizzes you at random times throughout your day, over notifications, until what you're memorizing becomes what you know.
Why ambient
Interruption beats intention
A study session is something you have to decide to do. An interruption just happens to you — closer to how you actually need to recall things, and no willpower required.
Completely unpredictable
You set the days, hours, and how often is too often. Inside those lines, UPLINK decides when to strike and how many questions to send. You never see it coming.
Cards never retire
Answer a card right fifty times and it still comes back eventually. Five years from now, UPLINK will still ask. That's the difference between cramming and knowing.
How it works
Load your cards
Write question/answer cards in the app — categories, decks, notes — or bulk-import a CSV straight from a spreadsheet.
Set your window
Weekdays 8 to 6, every day around the clock, whatever fits. Choose the minimum and maximum gap between pushes and a daily cap.
Get quizzed out of nowhere
A notification lands with real questions on it. Tap, answer, grade yourself — Got it or Missed it — and get back to your day. Misses return within minutes; streaks drift out toward years.
Features
Spaced repetition
A streak-based engine finds each card's natural frequency. Struggling cards hover close; mastered ones space out to months and years.
Batches scale with silence
A quiet morning earns a bigger batch. Per-push and per-day caps keep it from ever burying you.
Per-deck interval caps
Force critical material — emergency procedures, limitations, formulas — to reappear at least every N days, no matter how well you know it.
Fix an accidental grade
Fat-fingered "Missed it" on a card you knew? Go back and change it — scheduling is corrected as if it never happened.
CSV import & export
Author in a spreadsheet, back up your collection, or share decks with anyone else who has the app. Grab the sample CSV to see the format.
Private by design
No account, no subscription, no server, no analytics. Your cards live on your device and nowhere else. Buy it once and own it.
