Studying by voice: hands-free spaced repetition

The biggest constraint on spaced repetition isn't the scheduling algorithm - it's whether you actually open the app on the days it asks you to. A lot of the minutes where you could review are minutes where your hands and eyes are busy: commuting, walking somewhere, doing chores. Voice study exists for exactly that gap.

How it works

You pick a scope - a whole class, a unit, or a single chapter - and Encodr reads each card's question aloud. You answer out loud, it listens for a match against the card's accepted answers, and moves on. No screen required. If you mishear a card or need a second to think, saying "repeat" or "skip" is recognised as a command rather than treated as a wrong answer - the system checks for those before it checks whether what you said matches the answer, so you don't burn a review by asking to hear it again.

Where it's genuinely better than screen study, not just a substitute for it

Voice study is worse than screen study for anything visual - diagrams, equations, multi-step problems. It's better for anything that's fundamentally verbal: vocabulary, definitions, names, dates, anything where the honest test is "can you say the answer," because that's literally what it's asking you to do. For that category of card, it removes the last excuse for skipping a review - you don't need your hands or your eyes, just a few free minutes and something to say the answer to.

Why it uses the same scheduler as everything else

Voice reviews feed back into the same interval system as tapped reviews. A card you get right by voice climbs the ladder exactly like a card you get right by tapping - there's one schedule per card, not a separate one per study mode, so switching between voice and screen mid-week doesn't fragment your progress or create two versions of the same deck to keep in sync.
