Description
Please note: This is a trial version. When the trial period expires, you will be requested to purchase to continue using the app.
Autosync is an automatic file sync and backup tool. You choose which folder in your device should be synced with which folder in your cloud storage account, and how. Autosync will then keep files in these two folders in sync with each other, automatically and without any additional efforts from the user.
The official cloud storage apps don't have automatic sync capabilities, or only to a very limited extent. The commonly offered automatic photo upload might suffice for simple photo backup but not for keeping photos on multiple devices synchronized. If you want automatic file sync between your device and your cloud storage, you need this app.
Autosync can be configured to do automatic file sharing between your devices, to back up selected folders in your phone to your cloud storage, or to make backup copies of important document folders in your cloud storage and save them in your device for offline use. These are a few examples of what you can accomplish with automatic file sync.
All file transfers and communication between user devices and cloud storage servers are securely encrypted and do not go through our servers. Outsiders, including us, will not be able to decrypt and hence see or modify any file contents.
If your cloud storage is not on the list, please check if it supports WebDAV protocol. WebDAV is widely supported by many storage service vendors.
LAN/SMB network drives are supported by Windows/Mac/Linux computers and NAS devices. This app can sync with them via local network.

----- This "Autosync Universal" app supports multiple cloud storage services in a single app. Users who use only one cloud storage may prefer one of our single-cloud "Autosync for ..." apps. They are smaller, have fewer features but are simpler and easier to use than this all-in-one app.
Recent changes: In this update we fixed a few bugs and made some performance improvements.

Comments on Autosync - File Sync & Backup for Android
★★★★★Jocelyn Oudesluys· Jun 9, 2026
Just works, exactly like I need it to. A great solution for syncing apps via my personal cloud storage.
★★★★★Walter Ragusa· Jan 27, 2026
I have a music folder (library) that I keep organized on my computer. That same folder is duplicated on my Cloud drive. I use Autosync to keep the music on all my portable devices synced with the original music folder. Works faultlessly.
★★★★★Rich Ge· Jan 29, 2026
Just what I was looking for, clear, straightforward app to sync my photos, however it is also fantastic for syncing files to and from my NAS in an ad-hoc fashion. Really like the interface design and the activity log is 👍👍
★★☆☆☆Giacomo camposto· Apr 24, 2026
I have paid for the full boat license many times and have loved the app. Recently however it has exhibited some buggy behavior, spurious "download skipped" activity on "upload only" folders, and the SMB sync to my own tail net is extremely unreliable, in that it says it connects, but the sync is full of errors. This is relatively new behavior, so I think they broke something in an update.
★★☆☆☆Roger Pickering· Jan 31, 2026
It's been a great software for what I want to back up all folders on my phone to my cloud storage service. I don't worry about potential loss of data now. However, recently there's been a problem with it abruptly re-uploading 4,525 audio files which have been on the phone's micros card for a long time. The developer still hasn't resolved the issue and hasn't responded to my mail and updates. It appears that s/he's become untrustworthy. On this basis, I can't fully recommend buying this app.

App stopped working last year, unless I had Google Play installed & Enabled. No error, no warning, just stopped syncing, and I didn't realize for weeks, resulting in data loss. This is despite having paid for the app. On the somewhat bright side, these issues caused me to find the competitor app Folder Sync, and it's a better alternative, that does for free what Autosync required payment for, so I'm sticking to Folder Sync now.

All file transfers are encrypted and do not pass through MetaCtrl servers, and outsiders cannot decrypt the contents.
