What's New in LeetCode

1.2.3

September 16, 2026

Bug fixes and performance improvements to make your LeetCoding journey even better.

User reviews

Can’t see failed cases

The mobile app version is completely useless when we can’t see the failed cases, or add them to the test cases.
The iPad version doesn’t have the handy symbols menu like the phone app.

Allow text of questions to be enlarged in Accessibility settings

Please allow for text to be enlarged using settings -> accessibility on the iPhone. Developers sit in front of computer screens all day and many of us have bad eyesight. Being able to enlarge text in questions would help tremendously.

Otherwise a nicely built app.

Good but needs improvements

Submissions don’t mention which test is failing

Missing some basic features

In the solution tab, there’s no way to sort the solution by the number of vote. Some questions have hundred of solutions. Without a sorting feature, the app is basically unusable.

App doesn’t load.

Why even make app if you don’t know how to handle iOS! Seriously app isn’t working in iOS.
