With the release of iOS 26.3, Apple introduces an extension of the notification functionality on the iPhone: from now on, notifications can also be forwarded to third-party accessories. This feature is similar to forwarding notifications to the Apple Watch; In the EU, users can also receive notifications on compatible headphones, smartwatches or other smart devices starting with iOS 26.3.
For the first time, Apple opens the door for manufacturers outside its own ecosystem to integrate more deeply with the notification structure of iOS. Of course, strict security and privacy guidelines apply: accessories must meet the new framework requirements in the Made for iPhone program. In this tip you can read how this function works, which devices are compatible and where you can find the settings once iOS 26.3 is available.
iOS 26.3 in beta
At the time of writing, version 26.3 of the software is in beta and the update is still being extensively tested. The update is expected to be available to all users in February.
Improved support for third-party accessories
Apple’s latest software updates make it easier for European users to use third-party accessories with their iPhone. The EU has required Apple to add full notification support. This means you can forward notifications to third-party accessories, such as smartwatches.
Set up notification forwarding
- Open Settings on your iPhone
- Navigate to ‘Notifications’
- Select ‘Forward notifications’
- Select the desired accessory
- Confirm the forwarding

The implementation has one limitation: you can only receive notifications on one accessory at a time. When you activate Notification Forwarding for a third-party smartwatch, your Apple Watch will automatically stop receiving notifications.
Link and connect accessories
In addition to forwarding notifications, connecting these types of accessories will also be improved and can be compared to connecting an AirTag, HomePod or AirPods with your iPhone or iPad.
Notification Relay Framework
The ‘Forward notifications to accessories’ feature uses the Notification Relay Framework, a new API that Apple makes available to developers starting with iOS 26.3. This allows supported accessories to receive and show notifications via their own interface, for example with a vibration, an audio signal or a small display. Your iPhone remains the central hub: data is never shared directly from iCloud or apps.
When an accessory connects, you must give explicit permission to share notifications. This permission can be set per device, just like with Bluetooth or location access. This gives you full control over which accessories can receive notifications.
