Questions, answered.

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.

Download Cuetto, move it to your Applications folder and open it. Cuetto finds your library on its own by reading the same settings your DJ software uses.

A short setup assistant then explains how Cuetto works, scans your library, shows its health score and helps you set up your tags. A quick tour of the deck follows, and you start swiping.

Getting started guideDownload and first launch

No account and no password. For the free plan you enter your email in the app and click the link we send you, then Cuetto activates by itself. If you start a Pro trial or buy Pro or Lifetime, you get a license key by email and enter it in the app. Lost it? You can have it sent again.

Lost your key?

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.

iPhone and iPad guide

Cuetto works with rekordbox's own My Tag system: four categories with up to 50 tags each. You can use our suggested setup, a minimal one, or your own. Don't use My Tags? Skip them and work with rating, color, genre and playlists, which sit on the same card.

Cuetto reads a copy of your library, so nothing changes while you work. Your tracks show up one by one as cards. You listen, add tags, rating, color, genre and playlists, then swipe to the next track.

Every edit goes into your Change List. When you're done for the day, close your DJ software and click Apply. Cuetto makes a backup, writes everything in one step, and you can undo it with one click.

Getting started guide

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

They wait in your Change List like every other edit. Only when you apply are they removed from your library, together with their cues and playlist entries. When you apply, you choose whether the audio files also go to the Trash. Nothing is deleted for good, and Undo brings them back.

Removing tracks from your library is part of Pro. On the free plan you can still sort out: those tracks stay in your Change List and everything else is applied.

Your to-do list for the library. Every tag, rating, color, genre, playlist and sort out lands there first. In Review you see all changes per track and can drop single ones before you apply.

Your library only changes when you apply. Until then you can quit Cuetto, restart your Mac or keep tagging for days. Your Change List stays.

Change List and Apply

Yes. Pick your whole library or a single playlist or folder as the source. Filters narrow it down: untagged, no rating or no color, recently added, a genre, a BPM range, a key or one of your tags. The search finds artists, titles and more.

You can sort by date added, title or BPM. A good start is the playlist you play most.

Filters and search

Once you've tagged a few dozen tracks, Cuetto learns how you tag and suggests tags for the next ones. It learns right on your devices, from your own library only. Nothing is sent anywhere.

A suggestion is only a hint on the card. It becomes a tag when you accept it. Suggestions are part of Pro.

Cuetto searches public music databases by artist and title and shows you what it found: artwork, label, year and more. You pick what you want. Like everything else, it's written to your library when you apply.

Looking things up works on every plan. On the free plan, artwork and info count toward your 50 tracks a month like any other edit.

You can have both open, but one device tags at a time, so two devices never change the same track at once. While your iPhone or iPad is tagging, your Mac pauses its deck and shows the new changes live.

Want to switch? Click Continue Here on your Mac, or tap Take Over on your iPhone or iPad. The other device stops, and nothing it already sent is lost. All changes end up in the same Change List on your Mac.

You can apply from your iPhone or iPad too. The writing always happens on your Mac, so your DJ software there needs to be closed.

One device at a time

Yes. On first launch, a setup assistant scans your library and helps you set up your tags. Then a short tour shows how the deck works. You can open it again anytime: from the Help menu on the Mac, or in Settings on iPhone and iPad.

Yes, on the Mac and on iPad with a keyboard. Arrow keys keep, sort out or move a track to later, 1 to 5 set the rating, and letters set the color. Press ? to see every shortcut.

All keyboard shortcuts

Cuetto for Mac updates itself. When a new version is ready, click Restart to Update, or it installs the next time you quit. Your tags, Change List, settings and license stay as they are. The iPhone and iPad app updates through the App Store.

Updates

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

Mac: macOS 15 Sequoia or later, Apple silicon or Intel. iPhone and iPad: iOS 18 or iPadOS 18 or later.

There is no Windows version.

Yes, with the cloud providers your DJ software offers for library sync (Dropbox and Google Drive). After applying changes, open your DJ software on the same Mac first and let it finish syncing before you open the library on another computer. Cuetto reminds you when it detects cloud sync.

No. Tracks on external drives work like internal ones. macOS asks once for permission to access the drive.

Cuetto edits your main library, not the exported device library on a USB stick or SD card. After applying, export or sync to your stick again as usual and your tags come along.

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

Only one app should write to the library at a time. Cuetto checks that your DJ software is closed before it applies anything and waits if it is not. Reading and tagging work while it is open.

No. Your music and your library stay on your Mac. Cuetto never uploads your audio files or your library.

When you look up artwork or metadata online, Cuetto sends the artist and title of that track to public music databases to find a match. With Remote Access, audio previews stream from your Mac to your phone through our relay and are not stored there.

Only if you agree. The setup assistant asks once, with nothing preselected. If you say yes, Cuetto sends anonymous daily counters, like how many tracks were tagged. Never titles, artists, file paths or anything from your library. You can change your choice in Settings at any time.

Privacy policy

Remote Access lets your iPhone or iPad reach Cuetto on your Mac at home over the internet. Tag on the train, in a hotel or between flights, and your changes land on your Mac. Remote Access is part of Pro and Lifetime and turns on by itself when you pair an iPhone or iPad. You can turn it off in the settings on your Mac.

Your Mac opens an encrypted outgoing connection to our relay server. Your phone connects to the relay over HTTPS. Every request is signed with a key that only your paired devices have, and your Mac accepts nothing without a valid signature.

You don't need to open ports on your router. Your library stays on your Mac; the relay only passes requests and previews through.

Remote Access guide

A Pro or Lifetime license, your Mac awake with Cuetto running, an iPhone or iPad you paired once at home, and an internet connection on both ends. You can try it with the free 7-day Pro trial.

Many guest, hotel and office networks keep devices from seeing each other. Use Remote Access there. A VPN on your Mac or phone can also hide the local network.

50 tracks a month on your Mac and on iPhone or iPad at home: swipe them, tag them, add artwork and write it all to your library. Plus Library Health, backup and undo. Removing sorted out tracks, tag suggestions and Remote Access are part of Pro, which you can try free for 7 days. No time limit, no account.

A track counts once per month the first time you keep it, sort it out or change anything on it. Editing the same track again costs nothing. Later and listening are free, and managing your tags (creating or renaming them) doesn't count.

Changed your mind? Undo everything on a track before you apply and you get it back. Changes you haven't applied yet carry over into the next month and count there.

You always see how many tracks you have left. The limit is counted per Mac and starts fresh on the 1st of every month.

Cuetto tells you, and nothing is lost. You can still listen, review, apply what you tagged and undo. On the 1st you get new tracks, or you start a free Pro trial and keep going right away.

In the free plan, applying needs an internet connection so Cuetto can count your tracks. With Pro you can apply offline for up to 14 days and keep tagging offline for 30 more days after that.

Pick Pro, yearly or monthly, and enter your payment details at checkout. Pro unlocks right away: your license key arrives by email and on the confirmation page. The first 7 days are free.

After 7 days, the plan you picked starts by itself. Not for you? Cancel before the trial ends and you pay nothing. There's one free trial per customer, and Lifetime has no trial.

How to cancel

Only if you don't cancel. When the 7 days are over, the plan you picked starts: €79 a year or €9.99 a month. We email you a reminder 2 days before the trial ends, so it never comes as a surprise.

Paddle, our reseller, takes the payment and emails you a receipt. The 14-day money-back guarantee covers that payment too.

In Cuetto on your Mac: Settings, License, Manage Subscription. That opens your subscription at Paddle, where you can cancel. You can also reply to any email from us or write to hello@cuetto.com.

During the trial: cancel before day 7 and nothing is charged. Pro keeps working until the trial ends.

After that: Pro stays active until the end of the month or year you paid for. Then Cuetto switches back to the free plan: tagging, applying within the free limit, backup and undo keep working, and Remote Access pauses. Your tags stay in your library.

So Pro keeps running without a break if you like it. No coming back to upgrade in the middle of tagging your library.

The free plan never needs a card. Payments are handled by Paddle, and we never see your card details.

Pro is a subscription: €9.99 per month or €79 per year. Lifetime is a one-time payment of €129 for Pro without a subscription. Lifetime is limited to 100 licenses. Remote Access on Lifetime is for one Mac and two phones or tablets (fair use).

Pro starts with a 7-day free trial. Lifetime has no trial, but every payment comes with a 14-day money-back guarantee.

On two Macs at the same time. You can free up a Mac in the app's settings to move your license to another one.

Your license stays valid. Enter your key again and you're set. Reinstalling on the same Mac does not use up a second activation.

Our online reseller Paddle.com is the merchant of record for all orders. Paddle handles payment, invoices, VAT and refunds. Prices include VAT where applicable.

Every payment comes with a 14-day money-back guarantee. For a refund, contact Paddle through the link in your receipt email, or write to us. EU consumers also have the statutory right of withdrawal described in our terms.

Refund policyTerms

Nothing for now. You keep Pro until the date in your welcome email. After that, Cuetto switches to the free plan unless you choose Pro. Nothing is charged automatically, and your tags stay in your library either way.

The beta is closed to new applications. Everyone else can try Pro free for 7 days.

Thank you for testing Cuetto and for every piece of feedback.

Check that both are on the same Wi-Fi and that Local Network access is allowed for Cuetto on the Mac (System Settings, Privacy & Security, Local Network) and on the iPhone. If the macOS firewall is on, allow incoming connections for Cuetto. Turn off VPNs for a moment.

Troubleshooting

Most of the time your DJ software is still running. Quit it completely and try again. If your library format changed after an update of your DJ software, update Cuetto first.

Troubleshooting

Open your DJ software after applying, then export or sync your USB stick again. The player reads the exported device library, not your main library.

Yes. Every apply can be undone with one click, and Cuetto keeps a backup of your library from just before each apply.

Check the status page. It shows live whether downloads, licensing, Remote Access, email and payments are working, and how they did over the last 90 days.

Tagging and your library live on your Mac, so you can keep tagging when a service is down. Licensing and Remote Access catch up once it's back.
