★★★★★ "Works as intended but the experience is not great. Can't create any text files or duplicate them. No way to add file paths as favorites even though there is a favorite tab. The UI/UX design is just really bad and needs a rework." - Ali Rozarra

★★★★ John W Thorburn 4/7/2026 v4.17.2
rubbish lets go of connection all the time and takes multiple tries to reconnect. reviews show that a long term problem and clearly Synology don't care.
★★★★ Alex Yau 3/19/2026 v4.17.2
keep saying "unable to perform this operation: 119"
★★★★ valenteer liria 2/24/2026 v4.17.2
can't log-in
★★★★ Josh Steckler 2/6/2026 v4.17.2
file is sitting waiting to download and will never ever start downloading. rebooted Nas uninstalled app no change.
★★★★ Andrey Smirnov 2/3/2026 v4.17.2
works, but only sometimes which is worse then never work at all. it backs up my photos but sometimes misses a whole bunch. so at first it make an impression of working fine but upon closer examination you cannot really rely on it
★★★★ Joel Jufer 1/29/2026 v4.17.2
App is constantly crashing. No thumbnail previews for mp4. It's better to rely on 3rd-Party apps, I resorted to Owlfiles. Synology Apps are unusable. Always nice to pay a premium price for hardware like a Synology NAS to then get it to use with really bad, not user friendly software.
★★★★ Gleb Palchin 1/20/2026 v4.17.2
Broken, gives error 119
★★★★ Alex Stone 1/18/2026
does not work
★★★★ Vien Trinh 1/12/2026 v4.17.2
Totally useless. Since day 1 it never connected. DMS 6.2.4
★★★★ Christian Mercado 12/2/2025 v4.17.2
I mean, what a bad app... connection issues, force closes... guys fix this!
★★★★ Larry Ducas 11/27/2025 v4.17.2
app is useless . crippled unusable. couldn't have been tested. utter waste of time
★★★★ Yarrow 11/18/2025 v4.17.2
Broken - Error 119
★★★★ James Hales 10/31/2025 v4.17.2
This app takes away the ability to paste your authentication code. the only option is to autofill from a message which doesn't happen because you're using an authenticator app.
★★★★ John Carimando 10/30/2025 v4.17.2
incorrect permissions for use. It only has photos and videos permissions ask. This app needs file access permissions in order to download data. Seems like a huge oversight on all these Synology helper apps.
★★★★ Otto Stoefka 10/29/2025 v4.17.2
Can not connect to my NAS from ALL Android Devices - I double checked my Login credentials and still can't. Uninstalled on my Pixel 10 Pro - still the same problem
★★★★ Xavier Gutierrez 10/24/2025 v4.17.2
horrible this app crashed every time it's impossible to download something from your server
★★★★ Emily Chan 10/16/2025 v4.17.2
Downloads fail all the time, but I have no problem accessing my Plex server hosted on the same NAS...
★★★★ John 10/8/2025 v4.17.2
The actual worst photo backup solution I've ever used, it breaks for no reason and doesn't tell you about it when it happens.
★★★★ Gwee YY 10/6/2025 v4.17.2
not always working
★★★★ Abhinav Kumar 10/2/2025 v4.17.2
looks out of date,behaves out of date, and is ultimately a trash app; it's there just so they can market "we have an app"
★★★★ Davor Jelacic 9/14/2025 v4.17.2
Garbage app
★★★★ Jake H 9/4/2025
dogshit app. synolgy is a garbage company
★★★★ Steven Russell 8/29/2025 v4.17.2
Recent app update keeps getting stuck on photo backup causing it to keep uploading the same photo or video again and again. Aside from not completing the backup, it's killing the phone battery
★★★★ David Miranda 8/11/2025 v4.17.1
Impossible to login
★★★★ Tomáš Ponik 7/16/2025 v4.17.1
It's absurd when photo backup after time stops working without warning. And to continue backup, you need to re-enter the 6-digit pin!!! Synology has been surprising me lately.
★★★★ Stefan Vladov 7/5/2025 v4.17.1
Couldn't even start using it. It keeps asking for some 6digit code and I've no idea where to get it from...
★★★★ Vic van Cooten 6/24/2025 v4.17.1
This app is built by people who don't use the app.
★★★★ Kev Quirk 6/8/2025 v4.17.1
doesn't work in DSM7
★★★★ Zaphod Beeblebrox Sr 5/15/2025
Won't let me auto-upload if I have notifications off. BUT the devs are bad at beta testing and assume everyone will have notifications on so the alert doesn't say to turn those on, just storage permissions. 🙄
★★★★ DeAndre Wilson 4/9/2025 v4.17.1
Absolutely dumbfounded as to why they stop developing arguably the most important freaking Synology mobile app. Jesus! 🤦🏾‍♂️
★★★★ noiwontusenumbers 4/4/2025 v4.17.1
File permissions are not working cannot download anything
★★★★ Paul Gibbons 3/27/2025 v4.17.1
the photo backup function is broken, no options to set the rules as specified in the help info, I can set the account, destination and source but not the rules. I used to rate Synology devices as really good, but the apps are absolutely rubbish at the moment.
★★★★ Stanislav Stupakov 3/9/2025 v4.17.1
poor ui
★★★★ Rick Schmitz 3/6/2025 v4.17.1
Refuses to login. Synology Drive logs in w/out issue, but not DS File. Synology Drive does not allow access to my files though. I am able to use a web browser as well to login. The problem is DS File... critical error....
★★★★ Keith Wood 2/6/2025 v4.14.2
Edit of original review: app has been broken for upwards of a year without resolution. Software development cycle at Synology is lagging so far behind acceptable that it's time to find a new solution. Another edit: I finally lost hope that they're ever going to fix permissions and found another CIFS browser for android. Coupled with VPN it's a better than 1:1 replacement. I'm happier without DS File.
★★★★ Filipe Governa 1/27/2025 v4.17.1
Spams you with unsolicited notifications
★★★★ Andrew Fuller 1/22/2025 v4.17.1
Won't work with synology 2FA and doesn't show attached usb drives anymore
★★★★ andrew k. 1/1/2025 v4.17.1
Cannot download files on Android 14. It notifies you that for permission is needed, but it's not available to give. Really stupid fail on basic functionality. I tried to clear the cache and purge the app, reinstalled, but still cannot download
★★★★ Bedrm Tv 1/1/2025 v4.17.1
Does not work
★★★★ geofre 12/21/2024 v4.17.1
Doesn't work anymore. Won't even let me log in.
★★★★ Ismail Momoniat (ishmo65) 11/23/2024 v4.17.1
Downloading of files or folders from my NAS does not work. App stops all downloads, continually asking to "allow storage permission". There is no such permission on my Galaxy S23. I have enabled "Photos and Videos" permission and disallowed all Notifications. Update: The download works when Notifications ate switched on ... but I don't need 500+ notifications for 500+ files ... Synology needs to sort out the app message (allow storage permission) and not spam me with msgs for every file download
★★★★ Daniel Thompson 11/20/2024 v4.17.1
Now shoves ads into your notification tray. Can't turn them off without turning off all notifications for the app.
★★★★ Tim Smith 11/3/2024 v4.17.1
Dark mode is long overdue and needed.
★★★★ Ciprian Nedelcu 10/23/2024 v4.17.1
This always asking for 2fa on my samsung s24 ultra, worked well on oneplus 8 pro
★★★★ Reynaldo Torres 10/23/2024 v4.17.1
Search doesn't work at all, that's the main purpose I would use this app for my synology.
★★★★ Eunice Cheung 10/17/2024 v4.17.1
Same problem as Jory Gilson reported in Jul 2024, no solution and no reply?
★★★★ R Jenkins 10/2/2024 v4.17.1
No way to get it to send you the six-digit code you need to log in
★★★★ Tijs Palings 10/2/2024 v4.17.1
The only permission that is needed is missing, file permissions. It is asking me to enable them, but they aren't listed in the permissions list
★★★★ Smitkumar Velani 10/1/2024
Hard to used and access
★★★★ David Workman 9/14/2024 v4.17.1
I agree with the earlier review, this app isn't working. It used to months ago but not now. Save yourself the headache of trying to make it work.
