Ratings and reviews

I like the portability of having Leetcode on my phone. I can solve questions in social settings without having to wall off the world with a laptop. However, the UX is frustrating at times. It freezes, you can't scroll through solutions (I copy and paste to my editor), and it's doesn't even have redo/undo buttons (you can only reset to a blank template).

App is genuinely good. Everything works smooth but, there's a bug i found. In previous weekly contests, if we select a problem, bottomsheet opens. If we close the bottomsheet and try to open it again, data about problem is not being displayed. we only see white bottomsheet. I think this is error caused by unhandled context when we close it first time.

It’s decent, but the mobile web version still feels better overall. Nice-to-have improvements: Restore a previous submission without manual copy/paste. Visual performance comparison (not just “beats X%”) with access to others’ code; available on desktop, missing on mobile. Auto-format button. “Use Test Case” when reviewing failed submissions (currently only right after submission, not in history).

What’s new

- Added interactive runtime and memory distribution visualizations
- Integrated efficiency analysis
