How to Set Your Custom Ringtone on iPhone: Share Sheet, GarageBand or Mac

TL;DR

After export, choose a route: on iOS 26 use the share sheet's Use as Ringtone (under 30 s); otherwise Open in GarageBand and share as Ringtone; for up to 40 s sync an .m4r through Finder on a Mac. Then pick the tone in Settings → Sounds & Haptics.

The problem

You’ve made the perfect clip. iOS still has no “set as ringtone” button for apps, and each route has its own rules, which is why many people give up at the last step.

Route 1: iOS 26 share sheet (shortest)

  1. After export, tap Share on the file.
  2. Choose Use as Ringtone. This needs audio shorter than 30 seconds.
  3. Name and save it.
  4. Settings → Sounds & Haptics → Ringtone and choose it.

Route 2: GarageBand (any recent iOS)

  1. Tap Open in GarageBand; Ringtone Genius generates a GarageBand project from your export.
  2. Open it in GarageBand (or save it to Files and open the .band project from Files).
  3. In My Songs, long-press the song → Share → Ringtone, name it and export.
  4. Choose it in Settings → Sounds & Haptics → Ringtone.

Route 3: Mac sync (up to 40 seconds)

  1. Move the exported file to your Mac (AirDrop or Files).
  2. For Finder sync you need an AAC file 40 seconds or shorter with the .m4r extension. Duplicate the export and rename the copy if needed.
  3. Connect the iPhone, open Finder, select the device and drag the file into the sync area.
  4. Pick the tone in Settings on the iPhone.

If it doesn’t show up

Check the length, that the file really is the exported M4A, and that you’re picking it under Ringtone, not Text Tone. See the troubleshooting guide.

FAQ

Which route should I use? On iOS 26 and later with a clip under 30 seconds: the share sheet. Otherwise GarageBand. If you have a Mac and a clip up to 40 seconds: Finder sync.

Does Ringtone Genius set the ringtone itself? No. Apple doesn’t allow apps to install ringtones directly. The app prepares the file and walks you through the system steps.

Do I need GarageBand? Only for the GarageBand route. It is free in the App Store.

Where do I choose the tone afterwards? Settings → Sounds & Haptics → Ringtone.
