Great but initial loading time due to fetching feels a bit long. Maybe try storing the data once fetched on ROM and everytime after opening the app, show that stored data until new fresh data from API request arrives in 2 or 3 seconds?..? Otherwise the app is great overall...😘

Better than expected: No password needed. Intuitive UI. Friends feature is a great addition. One area of improvement: The contest screen is unresponsive - nothing on click or scroll. Giving 5 star despite contest screen issue as most paid apps will likely not be as good as this.

Freddy Zion

This is so amazing 😍😍. Interactive UI, questions for different levels of programming, code problems from famous companies... This app is all in one. Keep up with the good work.

Hello, been using this app for sometime now. Lovely experience. I have one requirement if you will be able to solve it. I generally maintain my streak for my personal milestone. Can we have a widget that can get data for daily submission or the problem of the day if that fire icon is glowed or not. Something that may be able to solve my purpose.

Gabriel Shaw

It's a nice way to quickly see your profile stats and the daily problem. My only complaint is that the time left for daily problems is wildly wrong. App must not be taking time zones into account.

Jenny Zhu

White screen after log in. Can't be fixed with rebooting or reinstall. And fixed immediately after posting this!! Impressed!

No way to pay to remove ads, so instead of being able to concentrate on a problem, you get annoying long ads every time you try to do anything. Useless. The regular Leetcode website in a mobile browser is a much better option.
