Older apps

Some LonelyDuck apps have a newer version, or a successor. This page says what happens to the older ones and what to do if you use them.

TuneBoi#

TuneBoi was retired in 2026. Tulip is its successor, built from what TuneBoi learned.

• It's no longer sold or updated.
• Your license keeps working, and the app keeps running on your Mac.
• The last version, TuneBoi 1.0.0, stays downloadable for owners at lonelyduck.io/tuneboi.
• Support still answers: support@lonelyduck.io.

Owner's notes#

TuneBoi cleans up a music library: duplicates, missing lyrics and album covers.

1. Install. Download TuneBoi from lonelyduck.io/tuneboi, open it, and choose your Apple Music library or music folder.
2. Activate. Copy the license key from your purchase email and enter it in TuneBoi.
3. Remove duplicates. Run a duplicate scan, review the results, then apply changes in batches.
4. Find lyrics. Search for missing lyrics, preview them, and save them to your tracks.
5. Fix album covers. Search for artwork and apply it so your library looks consistent.

Moving to Tulip#

Tulip looks after the library you keep in the Music app and changes nothing until you approve it, with undo for 30 days. It needs a Mac with Apple silicon and macOS 14 or later, and it's free to browse and check your library. See the Tulip guide.

Tulip 1.0#

Tulip 2 is a new app, rebuilt from the ground up, and it's in beta (2.0 beta 2). Tulip 1.0 is still the stable version, at lonelyduck.io/download.

If you bought Tulip 1.0, you don't pay again. Your Tulip 1.0 key works in Tulip 2 on up to 3 Macs, at no cost:

• On a Mac where Tulip 1.0 was activated, Tulip 2 finds the key Tulip 1.0 saved and offers Upgrade for free the first time it opens. macOS may ask you to allow Tulip to read it.
• On another Mac, paste the key from your Tulip 1.0 purchase email in Tulip 2's Settings › License. Tulip recognises the key by its last four characters: "Activating moves it to Tulip 2 Pro on 3 Macs, at no cost."

Tulip 2 never writes Tulip 1.0's files. To try it, download the beta from lonelyduck.io/tulip. The Tulip guide describes Tulip 2.

Canto 0.10.3#

Canto 0.10.3 is the stable release. Canto 1.0 is a rebuild that's in beta (1.0 beta 3), and this guide describes 1.0.

• Downloading 0.10.3: lonelyduck.io/download, or "Prefer the stable release?" under the download button on lonelyduck.io/canto.
• Updates: a copy of 0.10 never receives a beta. It keeps getting stable updates.
• Your license: a 0.x license works in 0.10.3. The first time Canto 1.0 reaches LonelyDuck, the license moves over to 1.0 by itself, covers 3 Macs, and includes 12 months of new Pro features. The license email for a new Canto Pro purchase also carries a key for Canto 0.10.

Moving to Canto 1.0#

The first time Canto 1.0 opens your vault, it updates your notes database and saves a copy from just before. Notebooks become notes, and a few features are gone. Read Upgrading from Canto 0.10 before you install the beta, and keep a backup.

Going back from 1.0 to 0.10.3#

If the beta isn't for you, you can go back. In short: export what you wrote in the beta, quit Canto, put the copy Canto saved before the update (Backups/pre-migration-v58-<date>.db in your data folder) in place of canto.db, then install 0.10.3. Going back to 0.10.3 has every step, and what happens if you open 0.10.3 without restoring the copy.
