FAQ
Frequently asked questions
Everything you need to know before you start reviewing.
How does the review scheduling work?
After each review, you rate how confident you felt. The system uses a spaced-repetition algorithm to schedule the next review at the optimal interval—shorter when you struggle, longer when you nail it.
Do I need to solve LeetCode inside the app?
No. You solve on LeetCode as usual, then add the problem here to track and review. We focus purely on retention, not the coding environment.
Can I import Blind 75 or Hot 100 in one click?
Yes. Curated lists like Hot 100, Blind 75, and NeetCode 150 are built in. Add an entire list with a single click and start reviewing.
Is my data safe?
Your data is stored on encrypted databases and we never share it with third parties. You can request deletion at any time.
Does it work on mobile?
Yes. We have a native iOS app on the App Store, plus a fully responsive web app that works on any phone, tablet, or desktop browser.
