How Smart Practice Works
The SM-2 spaced repetition algorithm - the same science used by Anki, Duolingo, and language schools worldwide - schedules each sign at exactly the moment you are about to forget it. Rate a sign Easy and it returns in a week. Rate it Again and you see it tomorrow. Over time, you build a permanent memory of every sign in the dictionary.
- Unlimited adaptive practice sessions - any time
- Automatic scheduling - signs appear when memory fades
- XP, streaks, and achievement badges track your journey
- Session stats: accuracy, time, XP earned per session
- Full dictionary access - all signs, all CEFR levels
Learn British Sign Language with Spaced Repetition
Smart Practice uses the SM-2 spaced repetition algorithm - the same science behind Anki, Duolingo, and every serious language school - to schedule BSL flashcard reviews at exactly the right moment. Instead of repeating every sign every day, the algorithm calculates a personalised review interval for each sign based on how confidently you rated it last time. The result: you spend less time practising and remember more for longer.
Rate Your Confidence
After watching each BSL sign video, rate yourself: Again (review tomorrow), Hard (in a few days), Good (in about a week), or Easy (in two or more weeks). The algorithm adjusts your next review interval instantly.
Automatic Scheduling
SignDeaf tracks every sign you have reviewed and when it is next due. Signs appear in your session automatically when your memory needs refreshing - you never have to remember to practise a specific sign.
XP and Achievement Badges
Every reviewed sign earns experience points. Level up from BSL Beginner to BSL Master, unlock achievement badges for review milestones and streaks, and follow your fluency journey on the progress dashboard.
Full BSL Dictionary Access
Practice spans all CEFR levels - from A1 everyday words like Hello and Thank You, through B2 conversational signs, up to advanced vocabulary. Every sign in the BSL dictionary is available to practise.
Frequently Asked Questions
- What is spaced repetition?
- Spaced repetition is a scientifically proven memory technique that schedules reviews at increasing intervals - just before you are about to forget. The SM-2 algorithm calculates exactly when each BSL sign needs to be reviewed to stay in your long-term memory.
- Is Smart Practice free?
- Yes - you can try Smart Practice with 5 free BSL signs without creating an account. Full access with unlimited sessions and adaptive scheduling requires a SignDeaf membership.
- How long does it take to learn BSL?
- Most learners see significant retention after just 10–15 minutes of daily Smart Practice. The adaptive algorithm maximises efficiency by only showing signs when your memory needs a refresh, so you do not waste time on signs you already know well.
- How is Smart Practice different from regular flashcards?
- Unlike static flashcard decks, Smart Practice schedules each sign individually based on your self-rated confidence. Signs you know well appear less frequently; difficult signs appear more often - building permanent long-term memory instead of short-term cramming.
- Can I practise a specific BSL sign?
- Yes. Every sign page in the dictionary has a Practise with Smart Practice button that opens a session starting with that exact word. The sign is placed first in your queue so you practise it immediately, then continue with other scheduled reviews.
