Hey! I’ve been building a personal project using Base44 and Claude AI and wanted to see if this is something people here would actually use.

It’s called MY Aespa Rank — a Progressive Web App (PWA), that you can add to your Home Screen and use it like a regular app without downloading from the App/google Store — where you rank aespa songs using an ELO battle system (like in chess).

The app is completely free and just for fun — no ads, no payments, and no monetisation.

It’s also safe to use: it’s built with Base44, which handles the hosting and security (HTTPS, secure data handling, no access to your personal data beyond what’s needed for the app to function). You don’t need to create an account to use it.

The app is still not finished and is currently in development.

You’re shown two songs at a time, and you just pick the one you prefer.

The more you play, the more the app builds your personal definitive aespa ranking automatically.

It includes all released aespa songs (except Get Going, We Go (English version), Rum Pum Pum Pum, collabs with one member, and OSTs sung by one member).

There’s also a feature where you can add any songs you want.

It covers the full discography from Black Mamba to Attitude, including the SYNK solo EPs, Hot Mess, and everything in between.

Main features:

• Head-to-head song battles

• A full ranked list based on your choices

• Audio previews while choosing

• Mood-based rankings (sad, hype, chill, etc.)

• Favoriting songs separately

Would you use something like this?

And what features would make it a must-have for you?

Even if your answer is no, I’d honestly love to know why 😊
