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.

Great App, extremely useful, does exactly what it's intended for. It's very well designed, with a greatly edfixie's UI (simple and logic). It's also quick, fast, and so reliable... I definitely recommend it... And I wish something similar (simple, efficient, straightforward, reliable, fast...) existed in PC/Windows... (other than the native (cumbersome, very limited, and really badly designed) Onedrive app...)

Just plain works. Ever since I started using OneDrive (and other cloud storage to be fair) it's been a nightmare to sync my Android phone. Now, everytime I charge my phone (you can control this, and all kinds of things in settings), it's synced to OneDrive - both ways (also controllable in settings). It's such a relief not to have to worry about losing data anymore and to be able to edit any file, from any device, at any time. The lie of OneDrive is finally resolved.

Thermal “Th3rMaLm3LtDoWn” Meltdown

I have been using this app for quite a while now, using the paid version. It was working fine, as I intended it to. Until right after an update glitches and resets all of my settings a few month ago. Causing it to try to send "and receive' data in both directions! So my phone was trying to back up my PC! My phone was absolutely FULL of data, it was just barely working! But I finally managed to get it to go back to a saved restore point from the day before on my phone. Working fine now.

Please double check the app folder pair config. OneSync only syncs what it is configured to sync. If you believe the config is correct, email our support team at We'll get the app log file from you and investigate.

What's new

In this update we fixed a few bugs caused by unusual accented characters in file names.

If you like our app, please give it a nice 5-star rating. If you run into issues or have questions, don't hesitate to email us at We'll follow up.
