Yes, Disk Drill for iPhone is available since the release of v4 of the application. But, you can only perform iPhone data recovery using macOS. The process is quite simple:
Connect your iPhone to the Mac device.
Find the iPhone in Disk Drill.
Scan the iPhone for recoverable data.
Review, and recover the deleted files as usual.
Users can recover lost data from the internal storage of the iOS device, as well as an iTunes backup. Disk Drill recovers lost data from an iOS device by first creating an invisible iTunes backup that contains the device’s databases, then scanning it for recoverable data.
