The idea
A problem solved once is easy to forget. Spaced repetition is an old and simple method: come back to it after a day, then after longer and longer gaps. leetty keeps track of the gaps, so you do not have to.
How it works
-
1 Add a problem you solved
Pick it from the list of LeetCode problems.
-
2 Solve it again when it is due
You solve it on LeetCode, as usual. leetty only keeps the dates.
-
3 Rate how it went
The rating moves the problem along the steps below. Once it moves past the last step, it counts as mastered and is not scheduled again.
Good to know
- Data lives in your browser
- There is no account and no sync. Clearing browser data deletes it, so export a copy to a file now and then; the same file moves it to another computer.
- Desktop only
- Made for a computer with a keyboard: every action has a key. The mouse works too, phones are not supported.
- A fixed schedule
- The steps above are the whole algorithm. It does not adapt to you, but you always know why a problem is due.
- Free
- No payments and no sign up.
Come back to old problems
before they look new again.
