Cuetto

Works with your rekordbox library

The right track is in your library. Can you find it in a second?

Cuetto helps you listen, tag and clean up your library one swipe at a time. At the gig, the right track is three taps away. You stay the selector.

The flood

I'm Nick. I play afro, melodic and tech house. Sometimes a private or business event, too.

Each month I dig through hundreds of new tracks and keep the best. Even those often stay strangers in my library.

  • Over 100,000 new tracks reach streaming services every day.Luminate, 2025
  • Genres that mean something different to everyone
  • Missing artist & title tags, no key, BPM or stars, no artwork
  • Files called track_03_final.mp3
  • The same track three times, one a 128 kbps rip
  • Tracks rekordbox can't find anymore

The moment

Saturday, 1:40 am. The room is ready for something special.

I know the perfect track is in my library. I just can't find it in time.

So I play the safe one. Again.

The detour

So I built something that picked tracks for me.

It matched BPM and key. It couldn't read the room: when the floor wants a vocal, a piano, a new mood.

My sets stopped feeling like mine.

So I built the opposite.Cuetto.

One track at a time. Listen. Swipe. Tag it in your own words.

Cuetto suggests. You decide.

  • 100+ tracks an hourReal tagging: listening through each track, 4 tag categories, rating and color. Not just swiping.
  • Your tags, your system: 4 categories, up to 50 tags each
  • Rating, color, genre and playlists on the same card

On the train. In the hotel. Between flights.

  • iPhone and iPad companion
  • Remote Access to your Mac at home
  • Everything syncs when you are ready

See what's missing. Fix it without fear.

  • Artwork, label and year looked up online
  • Duplicates found
  • Backup before every change
  • One click to undo

Same club. Same moment.

Three taps. Fourteen tracks. The right one.

  • Filter by your own tags right on the player

Nick Waves, the DJ who built Cuetto

A note from Nick

Why I built this

Anyone can mix now. Sync, key detection and auto cues made the technical part easy. What still makes a DJ is what you play next, and why.

One of the biggest names in house music calls his own library a maze. Another says DJing has gotten far too easy. I know both feelings.

Crowds want this week's remix and move on fast. Every week my library grew faster than I could listen to it. So I spent months building an algorithm that picked tracks for me. It worked, technically. And my sets stopped feeling like mine.

So I built Cuetto the other way round. It takes the chores. Every musical decision stays with you.

What gets in the way

Three problems, solved.

Three things kept getting in my way. You probably know them too.

  1. Can't find it at the gig

    You know the track is in there. You scroll, the moment passes, you play the safe one.

    With Cuetto

    Tag tracks in your own words. At the gig, filter by those tags right on the player, and thousands of tracks become a short list.

    Over 100,000 new tracks reach streaming services every day.

  2. No time to keep up

    New music lands every week. Listening to all of it properly takes longer than you have.

    With Cuetto

    One track at a time: listen, swipe, tag. On the Mac, or on your iPhone and iPad on the couch or the train.

    100+ tracks an hour.

    Real tagging: listening through each track, 4 tag categories, rating and color. Not just swiping.

  3. Chaos, and the fear of breaking it

    Duplicates, missing artwork, genres that mean nothing. And you don't dare touch it, because your cues and playlists took years.

    With Cuetto

    Library Health shows what's missing and helps you fix it. Every change waits in your Change List until you hit Apply.

    Backup before every change, one click to undo.

Questions

Before you ask

Short answers. Everything else is in the FAQ.

All questions

What is Cuetto?

Cuetto is a Mac app for tagging your rekordbox library one track at a time, with a companion app for iPhone and iPad. You listen to each track, add your own tags, rating, color, genre and playlists on a single card, then swipe right to keep it or left to sort it out.

Every change waits in your Change List first. When you're ready, click Apply and Cuetto writes it all to your library in one step, with a backup made just before.

What do Keep, Sort Out and Later mean?

Keep: swipe right. The track stays in your library with your edits and the next card comes up.

Sort Out: swipe left. The track is marked for removal, for example because it's a duplicate, a broken file or just not your sound. Nothing is deleted right away.

Later: swipe up, or tap or click Later, when you're not sure yet. The track moves to the end of the queue.

Changed your mind? Undo takes back the last swipe or edit.

Swiping and shortcuts

Which DJ software does Cuetto work with?

Cuetto works with rekordbox 7 libraries on macOS. rekordbox 6 and older versions are not supported.

If a rekordbox update changes the library format, Cuetto tells you right away. You can keep tagging, and applying works again once you update Cuetto.

rekordbox is a trademark of AlphaTheta Corporation. Cuetto is not affiliated with AlphaTheta.

System requirements

Can Cuetto break my library?

Cuetto is built to make that very unlikely. Nothing changes in your library while you tag. Your changes wait in the Change List, where you can review them, and they are only written when you click Apply.

Before every apply, Cuetto makes an automatic backup of your library. Cuetto also checks for conflicts, so it never overwrites something that changed in the meantime. If you don't like the result, undo the whole apply with one click.

Change List and Apply

Can I tag on my iPhone or iPad?

Yes. The free companion app for iPhone and iPad connects to Cuetto on your Mac. At home on the same Wi-Fi this works on every plan. From anywhere else, you need Remote Access, which is part of Pro and turns on by itself when you pair.

The app is coming to the App Store soon, free of charge. Follow the download page to hear when it's out.

The companion is not a standalone app. Your Mac needs to be on with Cuetto running.
