Transform your coding fluency through consistent, focused practice
Repetitive typing of common patterns helps your fingers remember syntax without thinking.
Daily practice improves your typing speed and reduces time spent debugging typos.
Spaced repetition reinforces learning and helps you remember syntax long-term.
Powered by Anki's proven SM-2 algorithm. Cards progress through New → Learning → Review phases. Rate each practice: Again (reset), Hard, Good, or Easy — the system adapts intervals automatically for optimal retention.
New Card
Day 1
First practice session. Rate: Again, Hard, Good, or Easy
Learning Phase
Day 2
Second review (1 day later). Master the basics before moving forward
Review Phase
Day 8
First spaced review (6 days later). Intervals now adapt to your performance
Mastery
Day 23+
Longer intervals (15+ days). Easy cards appear less, hard ones more frequently
A simple, effective workflow to master code through spaced repetition
Organize code snippets into custom decks. Free users can create up to 2 decks, Pro users get unlimited decks.
Type code snippets in our dual-editor interface. Track your speed, accuracy, and progress in real-time.
After each practice, rate your performance: Again (reset to learning), Hard (difficult but correct), Good (correct), or Easy (effortless). The SM-2 algorithm adjusts intervals based on your ratings.
Cards you find easy appear less frequently, while challenging ones come back sooner. Build lasting muscle memory.
