Comments on Autosync - File Sync & Backup for Android

★★★★★ Nathanial Price · Dec 23, 2025

I was looking for an app to help sync my phone files to my Green NAS but all the others I found didn't have everything I needed, like 2-way sync for instance. This one gives me that and more. It is paid, but it's $10 lifetime, worth it.

★★★★★ Matthew Henderson · Jan 10, 2026

Set it and forget it. No ads, pop-ups or demands for more money. Set it up once, and it does exactly what you want seemingly indefinitely. This app has been backing up my phone storage (pictures and documents) through a VPN to a local smb drive seamlessly for two years now without any fuss, hiccups or corporate bloat trying to sell me something else. 10/10

★★★★★ 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.

★★★★★ Selva kumar Kuppusamy · Jun 6, 2026

This application offers excellent functionality for synchronizing specific folders with Google Drive or other cloud storage platforms.

★☆☆☆☆ Another Human · Nov 10, 2025

1) TRASH compared to the free one called ST. 2) It doesn't even sync recently modified files first but rather every file. So VERY slow 3) They definitely throttle the ad-supported version: so BAD LUCK, you gave a bad impression! So I'll get a refund on the PAID v 4) Support /SALES ignores emails 5) Dishonest: they sold many "Ultimate" upgrades promising all future upgrades, then DUMPED that for subscription version. 6) What sort of greedy idiots show an AD when you hit UPGRADE? Own worst enemy!

★★☆☆☆ 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.

★☆☆☆☆ T · Feb 8, 2026

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.

Trust & Safety: The app requests a broad set of permissions (including location, storage, network, and background services) to enable reliable sync across devices and clouds. All file transfers are encrypted and do not pass through MetaCtrl servers, and outsiders cannot decrypt the contents. This design emphasizes client-side protection of user data while enabling robust sync functionality.
