Purchase error

“An error occurred during purchase”

Response from developer

The purchase library has just been upgraded. Please let us know if the issue still occurs after updating. Best, Willie

Overall Good but need some improvement

I like the smooth transitions, card swiping, and organization features, but the quiz feature still has room for improvement.

Response from developer

Thank you so much! We put a lot of time and effort into creating a great user experience, from the UI design to the overall layout, so we're really glad you like it. We're also working hard to expand and improve our quiz bank. Stay tuned for more updates! Best, Willie

Needs a lifetime option

Overall good for reviewing leetcode on mobile, would like the option to buy a lifetime access. Not a fan of the subscription model.

Response from developer

Reasonable request. Some additional context: I removed the lifetime option last year due to the introduction of AI integration features. Especially since Claude is quite expensive and token hungry. But if a lot of users really want a lifetime option, I can definitely see what common ground we can achieve. In the app, you can leave a community request and let’s see what others think about it. Best, Willie

It’s okay

I think this misses the point entirely of what leetcode is it’s just problem solving, basic analogy is your a Gardner and you need tools the ds and algorithms are the tools doesn’t matter the problem but this app focuses what too much on the problem who’s going to genuinely going to remember all the
problems. The patterns and the quites keep repeating themselves within the 15 questions like 5 times. And there seems to be lacking in the quiz area. There needs to be more focused patterns and clear coding tools

Response from developer

Fair enough. You make a very valid point. I just want to point out that this tool was never designed to help you memorize all LeetCode problems. It’s simply a tool that lets you write down notes, imagine a quick scribble on paper or a sticky note. I had fun in mind when I started this project in 2024, so most of the features are gamified elements that I wanted to include lol. As a software engineer myself, I didn’t really spend time doing LeetCode, so I might have neglected the pain points users may encounter. I will keep listening to all the feedback and see what I can do next. Anyway, I’m glad you at least started a free trial of the Pro features and tried some of them. And yes, a lot still needs to be improved in the quiz feature. Thank you for all your constructive feedback. I will rethink the approach and revise it in future release. I really appreciate it. Best, Willie

Useless

Just a bunch of ads

Response from developer

These ads support the development and maintenance of LeetCard. I will try to keep them minimal. Best, Willie
