The science of never forgetting.
Ebbinghaus proved we forget 70% of information within 24 hours. Reminda's SM-2 engine calculates the exact moment your memory starts to fade — and delivers a review precisely then, burning knowledge into long-term memory with minimal effort.

The Algorithm
SM-2: the proven interval formula
Developed by Piotr Wozniak in 1987, SM-2 uses your performance on each card to compute the optimal review interval. Answer correctly → interval grows. Struggle → interval resets. Over time, each card's interval adapts to your specific retention curve.
SM-2 Interval Calculation
> First review: 1 day
> Second review: 6 days
> n-th review: I(n) × EF
> EF = Ease Factor (2.5 default, adjusted per answer)
> Result: 94% retention at 30 days

Spaced repetition FAQ
Does Reminda use the actual SM-2 algorithm?
Yes. Reminda implements the SuperMemo SM-2 algorithm with ease-factor adjustments. Each card gets an individual retention profile based on your performance.
Can I override review timing manually?
Yes. You can mark a card as easy, hard, or skip it entirely. Reminda adjusts the interval accordingly without breaking your overall deck schedule.
Does spaced repetition work for all subjects?
SRS works best for factual, discrete knowledge: vocabulary, definitions, formulas, code syntax, historical dates. For procedural skills, pair it with active practice.
How many cards should I review per day?
We recommend starting with 10-20 new cards/day and 20-40 review cards. Reminda's scheduler balances this automatically so you never feel overwhelmed.
