Frequently asked questions about OOO for iOS

How secure is OOO?
We don’t store or send any personal information. To establish a connection between two devices, we use WebRTC, which Google and Facebook use for their video-conference apps. 

Do I need a mmhmm account in order to use OOO? 
Nope! You can use OOO whether you have a mmhmm account or not.

Does OOO work with mmhmm on Desktop?
OOO allows calls only between iOS and iPadOS users. In the future, the app will work with other platforms like Windows and Mac.

Why is it called OOO?
OOO’s name comes from the acronym for “out of office,” and taking you out of the formal office grid is exactly what we want to do. 

Can I use OOO on all of my devices?
We are hard at work on making the app cross-platform compatible, but it is currently only available on iOS and iPadOS. We will offer OOO for other platforms in the future!

What is the recommended size of a room image for OOO?
We recommend 1080x1920 for the portrait mode.

Why can my friend use the dual-camera feature, but I can’t?
Currently, dual-camera support is only available on newer iPhones and iPads. Please refer to the list below for which iOS devices dual-camera is compatible with:


  • iPhone – XS series XR and later
  • iPad Pro – (3rd Gen) and later
  • iPad – 8th Gen and later

Not Supported:

  • iPhone – SE (1st Gen), 5, 6, 7, 8
  • iPad Pro (2nd Gen) or earlier
  • iPad – 7th Gen and earlier

Is this the same thing as Teleport?
Yes! We previously referred to this as Teleport, but decided to go for another palindrome.
