First discovered by Italian blog Aggiornamenti Lumia, the companion app is said to support the fast transfer of photos and videos from Apple smartphones to PCs provided they're connected to the same Wi-Fi network. The app appeared briefly as an update on the Windows Insider "Fast Channel" and should become available to all Windows 10 testers soon.
The app seems to be for people who don't use Microsoft's OneDrive cloud backup service, as it replicates some features already available in the OneDrive app, which lets users upload pictures from an iPhone and import them directly into the Windows 10 Photos application.
The new software is part of Microsoft's wider mobile strategy to improve its iOS offerings, now that Windows 10 Mobile hardware is no longer a focus for the company. Microsoft officially ended support for Windows Phone back in July, and is no longer developing new features or hardware for Windows 10 Mobile.
