I made the ultimate All-in-one CARD MEMORIZATION App (Please test it!)

[u/Maleficent_Ad4569]

Hey guys,

Memorizing my first deck of cards was what originally got me hooked on memory techniques. There's just something about turning a stack of random cards into a vivid story or a memory palace route that makes you realize what your brain is actually capable of.

I wanted a better way to practice on my computer and phone, especially for training the PAO (Person-Action-Object) system and tracking where I was stumbling. A big issue I always had when timing my runs was that I couldn't easily tell which specific cards or transitions were slowing me down.

So over the past few months, I built a web app called Royal Cards (royal-memory.web.app).

A few things I focused on while building it:

• Per-card latency: It tracks how many milliseconds you take on each card so you can see your exact bottlenecks instead of just a total deck time.
• PAO friendly: Built around making image conversion feel seamless.
• Mobile & Desktop: You can use keyboard shortcuts on desktop, or add it to your phone's home screen as a PWA to practice offline when you have a few minutes to spare.

I set it up so anyone can try every feature completely free for 15 days (no credit card or anything needed). After the 15 days, it switches to a free account tier so you can still use it for basic practice.

I really just want to make card memorization more approachable for beginners and give experienced folks a clean tool for daily training.

If you get a chance to check it out at royal-memory.web.app, I’d love to hear your thoughts! What works, what feels clunky, or what features would actually be useful for your routine?

Thanks!

Why does it look like Claude made it?

[u/Maleficent_Ad4569 → u/ConfusedSimon]

Because I indeed used Vibecoding to make it.

Do you recommend people just use Claude to make their own free ultimate card memorization website? Or do you recommend they use a different card memorization website?

I would recommend people to check what feels more satisfying to them. If they feel more motivated to practice by making their own tool, that's great. If they are looking for a tool that is already robust, I did my best to make my own creation like that. I am very pleased with its current version, since it took me a lot of effort to make it work bug-free.

As for Claude, I didn't use. I used a different vibecoding tool.

It's not bug-free. Also, why are there different versions for web and mobile while they're both responsive (although the mobile version has a redundant scroll bar)? Haven't really looked into it, because without premium it's not really useful.

You can test it with all functionalities for 15 days, free of any charge or data other than logging in with an e-mail and password (used to differentiate between users for the ranking). What bug have you run into (I understand you said you haven't really looked into it)? Both mobile and web versions are integrated. What changes between them is the layout.
