How we evaluated

We ran each app through a four-week exam-prep simulation: multi-subject syllabus, daily opens, offline use, and honest friction logging. Rankings weight retention of use over feature checklists — because an abandoned algorithm helps no one.

We also separated flashcard apps from revision planners. That distinction matters more than most roundups admit.

Revu: spacing as a calendar, not a card factory

Revu occupies a lane the flashcard giants ignore: topic-level spaced revision. You schedule “Organic Chemistry — Chapter 4” for review on day 3, 7, and 14 — with reminders, notes, and tags — without converting every fact into a card.

For students juggling six subjects, that model often beats a pristine Anki deck that never gets built. Spacing is the intervention; cards are optional.

Spaced revision on a calendar you will open

Revu schedules topic reviews with reminders — the forgetting curve, met on purpose, without the card grind.

AnkiMobile: still the flashcard benchmark

AnkiMobile earns its reputation and its price tag when your job is thousands of atomic facts — medical terms, language vocabulary, legal definitions. FSRS support on iOS makes intervals smarter for disciplined users.

The catch is familiar: card creation becomes a hobby. If you would rather revise than manufacture cards, look elsewhere.

Quizlet: fastest path to a shared deck

Quizlet wins when your class already has a deck and you need to study tonight. Learn mode gamifies repetition. Long-term retention control is weaker than Anki or a dedicated planner — but speed matters in week one.

Brainscape and RemNote: specialised fits

Brainscape’s confidence ratings feel humane for beginners who hate Anki’s cognitive load. RemNote suits students who live in notes and want cards to spawn from headings — powerful, but not light.

Pair with ReadFast for the reading half

Study apps handle recall. They do not finish the PDF. ReadFast covers RSVP reading, focus mode, and PDF import — a sensible second app when your bottleneck is getting through material, not scheduling review.

Also consider · ReadFast

Finish the readings first

RSVP speed reading and focus tools for the material your study app will later help you remember.
