Simple Flashcards vs Spaced-Repetition Apps

Spaced-repetition apps like Anki schedule each card at the moment you are about to forget it. The algorithm is genuinely excellent, backed by a century of memory research. For long hauls, thousands of words, medical school, it is the right tool. So why do so many beginners install one and quit within a month?

Because the algorithm has a personality: it is a debt collector. Miss three days and you return to 400 due cards, a number that reads as a judgment. The app is optimizing your memory; nobody is optimizing your motivation. For a beginner whose real risk is quitting, not forgetting, this trade is backwards. The scheduling advantage of SRS over simple review is real but modest at the 1000-word scale; the abandonment risk is enormous.

A simple deck, sorted by frequency band, with a known/still-learning split, gives you 80% of the benefit with none of the debt. Come back after a week off and nothing scolds you; band 4 is where you left it. You review the still-learning pile more often, glance at the known pile occasionally, and that is spaced repetition in spirit, done by hand, with your motivation intact.

The honest split: use a simple system for your first 1000 words, while the habit itself is the fragile thing you are building. If you reach 1000 and want to push toward 5000, graduate to Anki; at that scale hand-managed review genuinely breaks down and the algorithm earns its keep. Tools should match the phase you are in, and the beginner phase is won by showing up, not by scheduling.
