Frequently asked questions
I'm not getting chat notifications in the iPhone app.
Notifications need two things: permission granted when ryOS asks, and being signed in to ryOS inside the app. If you answered no to the notification prompt, reinstalling the app gives you the prompt again. When the app is closed, notifications arrive through Apple's push service — allow a minute or two for the first one.
The desktop loads slowly the first time (iPhone app).
The first launch downloads the desktop from the web. Every launch after that comes from the cache on your phone and starts fast. The download only happens once.
Does the iPhone app work with no internet?
Yes. Once the desktop has been loaded once, it starts from the cache on your phone without a network. A banner tells you when the app is offline.
How do I sign out or delete my account?
Everything about your ryOS account — signing out, deleting your account, exporting your data — lives in the desktop's Control Panels, on the web and inside the iPhone app alike.
Does the iPhone app work on iPhone Duo?
Yes. Fold it open and the desktop fills the large inner display; fold it closed and it fits the cover display.
Can I use ryOS without an account?
Yes. Most of the desktop works without signing in. An account is optional and only needed for features like cloud sync and sign-in-only chat features.
