What’s New Version 2.1.0
Same-day re-rates now stick: if you review a problem twice in one day, your latest rating is the one that counts — on this device and everywhere you sync.
• More reliable cloud sync: smarter merging of your review history across devices
• Settings like your daily review goal now sync consistently between mobile and web
• Under the hood: PatternBank mobile and web now run on the same shared engine, so improvements land on both at the same time
Description
Stop forgetting LeetCode solutions. PatternBank helps you retain what you practice by turning solved problems into confidence-based spaced repetition reviews.
Solving hundreds of problems is not the same as remembering them. PatternBank gives you a focused system for tracking what you solved, how confident you felt, which patterns were involved, and when you should review next.
Use PatternBank to:
- Track algorithm problems by title, difficulty, confidence, notes, and patterns
- Review problems on a spaced repetition schedule
- Rate confidence from 1 to 5 stars after each review
- Connect public LeetCode Activity to bring recent accepted submissions into Today
- See due reviews, LeetCode solves, and completed work in one daily workflow
- Track progress by pattern, review history, confidence trend, and 30-day projection
- Exclude problems you do not want in the review queue
- Start locally without an account, then sign in when you want cloud sync
PatternBank is built for technical interview prep, algorithm practice, and long-term recall. It keeps the workflow simple: capture the problem, rate your confidence, review what is fading.
LeetCode Activity uses public profile activity. PatternBank does not ask for your LeetCode password.
