Pia
Free flashcards. On device.
Coming soon to the App Store
Serious spaced repetition for people who study for a living, free and private.
Pia is built for medical, law and graduate students who live in their decks. It runs a state-of-the-art scheduler, ships hundreds of decks ready to go and opens the Anki files you already have. Everything happens on your phone, so the work stays fast, stays private and stays yours.
FSRS-5 scheduling
A modern spaced-repetition engine that schedules each card for the moment you are about to forget it. The classic SM-2 algorithm is there too if you prefer the old way.
573 free decks
A full library covering USMLE Step 1, Step 2 and Step 3, internal medicine and the complete MCAT, ready the moment you open the app.
Bring your own Anki
Open any .apkg deck you already own and export yours back out whenever you like. Your work is never trapped in someone else's app.
Image occlusion
Hide parts of a diagram and test yourself on what sits underneath. Built for anatomy, pathways and anything you learn by sight.
PDF to cards
