About Nine
Nine is a mobile email and calendar app for Android and iOS. It uses Direct Push to synchronize with Exchange-family servers, and it also works with IMAP servers. With an ActiveSync account it syncs email, calendar, contacts, tasks and notes in one app. With IMAP it currently syncs email only.
The developer also offers Nine Work, an enterprise edition that can integrate with mobile device management (MDM) systems. Nine suits people whose work mail runs on Exchange or Microsoft 365 and who want those accounts on a phone.
