What does a phone synchronizer do?

It lets you control several Android cloud phones by working in just one of them. Instead of repeating every tap, swipe, scroll and keystroke on each device, the Synchronizer passes those actions to the phones you selected as you go.

The Synchronizer copies actions.

It never shares:

Account data

App storage

Device identity

Device settings

Proxies

Separate phones, shared actions.

Each cloud phone stays its own Android environment, with its own app data, settings, proxy and login. Syncing repeats actions without merging any of that.
