On iPad, please enable Files integration in the app's preference.

Sync via third-party cloud storages

"Files Integration" makes it easy to sync projects across multiple devices of the same user via Dropbox, OneDrive, Google Drive, etc. Below is an example of syncing projects via OneDrive.


The OneDrive service controls file transfer, and the app has no control over when and how project files are transferred between devices.

In most cases, OneDrive works well, and file syncing is fast. However, if you find that the sync is not completing on time as expected.

  • Please make sure that you are using the SAME OneDrive account on multiple devices.
  • Go to the OneDrive website to verify that the project files have been transferred to the OneDrive server.
  • To verify that the project files have completed synchronization with the device, check the project files in the Files app (developed by Apple) or the OneDrive app (developed by Microsoft) on the iOS device.
  • Check the time of the last modification of the project file on the device to ensure that synchronization is complete.


Some users may expect to be able to edit the same project (opened directly from OneDrive) on multiple devices simultaneously, and the changes should be automatically transferred to other devices. We would like to emphasize here that editing the same project on various devices at the SAME time via OneDrive is not possible.

Since tasks in the project plan are in a TREE structure, there are close relationships between them. For example, the date constraint relationships via task links, the parent-child relationships via task group hierarchies.

Editing two or more task items at the same time leads to significant logical problems. The following are some cases that can lead to logic problems when editing on two devices simultaneously:

  • (On device A), add a task to a task group; (On device B), remove the same task group.
  • (On device A), assign a project member to a task; (On device B), remove the project member from project resources.
  • (On device A) move a task to the modification date; (On device B) move another task that is the successor to the moving task on device A.
  • (On device A) we find that the project data has been changed unexpectedly. For example, the task work is "automatically" updated to an unexpected value. We are confused and think it is an error; (On device B) someone else has actually changed the task work on device B.
