About this app

This app is an automatic file sync and backup tool. It lets you automatically synchronize files and folders with Microsoft OneDrive cloud storage and with your other devices. It is an ideal tool for photo sync, document and file backup, automatic file transfer, automatic file sharing between devices,...

New files in your cloud account are automatically downloaded onto your device. New files in your device are uploaded. If you delete a file on one side, it will be deleted on the other side. It works across multiple devices (your phone and your tablet). If their folders are synced with the same cloud account, they will be kept in sync with each other.

This is how OneDrive works on computers but not on Android. Two-way automatic synchronization should be an essential function of the official app. For whatever reason, it is not the case. OneSync is here to fill the gap.

All file transfers and communications between user devices and cloud storage servers are securely encrypted and do not go through our servers. No outsiders will be able to decrypt, see or modify any file contents.

• Full two-way automatic synchronization of files and folders
• Many sync modes. Not only two-way, you can also choose Upload only, Upload then delete, Download only, Download mirror,...

PLEASE ADD THIS FEATURE! Can you please add a feature where if it doesn't sync one file it'll atleast push on to the next one. Special characters like æß vç AND ESPECIALLY JAPANESE CHARACTERS and a million others won't sync and will cancel the whole thing. And then when it's done just show the ones that couldn't sync PLEASE!!!!!

It kind of works but a lot of basic functionality is locked behind a paywall. The ads in this app are VERY intrusive; I pressed the sync button and was forced to watch a video ad before I was allowed to do the sole thing the app is for. Another ad popped up full screen with a fake close button during setup. I would have potentially paid after some evaluation, but the experience just left me feeling slimy and like I needed to take extra measures to secure my account after uninstalling.

Hi, we understand the ads can be annoying to some users. We encourage you to pay for the upgrade to get rid of the ads and unlock all features. It's just a small one-time payment. BTW the ads are supplied by Google. We have little control over how they look and behave.

Great App, this is what sync clients should be. I have been using it for years, it is the primary way I get files on and off my phone. Update 10/5/2021: Still using this app every day and it is by far one is the apps that I get the most utility from. As long as I am in the Microsoft ecosystem, this will be indispensable. I don't know how folks get along with the official OneDrive app when this is available.
