AppSuite:OX Sync App

From Open-Xchange

OX Sync App

OX Sync App was a native mobile phone app for Android built specifically for smartphone users , that also have a valid OX App Suite account. The app was designed to let users sync their OX App Suite Appointments, Tasks and Contacts environment directly from a native mobile phone client. The OX Sync App was designed specifically for ease-of-use and is available for Android only.

Please note: Development of the OX Sync app by Open-Xchange has ceased, and it will be removed from the app stores by end of December 2025. Open-Xchange will be working in the upcoming months to deliver a new and enhanced solution for seamless integration of Android mobile devices with OX App Suite. We are committed to providing a great mobile user experience for our OX App Suite users on Android.

CalDAV and CardDAV for Android with OX Sync and DAVx⁵

OX App Suite supports the open synchronization standards for calendars (iCal) and contacts (vCard) through CalDAV and CardDAV. Unfortunately Android lacks native support for these open standard, while iOS supports it fully. To facilitate synchronizing calendars and contacts between Android and OX App Suite, we recommend to use the Open Source synchronization software DAVx⁵. It is completely compatible with OX App Suite and provides reliable background synchronization.

Installation of DAVx⁵ on your Mobile Device

You can download the app via https://www.davx5.com/download, it is available in multiple Android App Stores. The download from F-Droid is free, while the downloads from the other App Stores cost a small amount that sponsors the development of the Open Source application.. Please proceed to download and install it on your Android mobile device.
