A home NAS only works if you can reach it from your phone. Photos backed up, films downloaded for a flight, a tax PDF pulled from a share at the worst possible moment. We compared seven of the most useful NAS client apps for Android in 2026, including the official Synology and QNAP clients, a Nextcloud companion for self-hosted setups, and the generic file managers that handle SMB, FTP, and WebDAV against any NAS you point them at.
What to look for in a NAS app on Android
NAS clients fall into three camps. Decide which one you need before installing five apps you do not use:
- Vendor clients. Synology DS file, DS finder, and Synology Drive plus QNAP Qfile Pro. These are tied to DSM or QTS and give you the full toolset for that vendor.
- Self-hosted clients. Nextcloud’s Android app pairs with a Nextcloud server (DIY, hosted, or a Synology HyperBackup target).
- Generic file managers. Solid Explorer and Cx File Explorer connect to anything that speaks SMB, FTP, SFTP, or WebDAV.
Other things to test before you commit:
- Photo backup. Synology Drive, Synology Photos, and Nextcloud all auto-upload from the phone. DS file does not.
- Streaming. DS file and Qfile Pro stream video from the NAS without downloading. Solid Explorer and Cx do as well, in their built-in players.
- External app handoff. SMB shares mounted by Cx File Explorer or Solid Explorer can be opened directly by VLC, MX Player, Lightroom mobile, or any app that accepts a content URI.
- QuickConnect, port forwards, or VPN. Reaching the NAS from outside your home means a vendor relay (QuickConnect, myQNAPcloud), a port forward, or a mesh VPN like Tailscale. The app supports the first two natively; the third runs in parallel.

The 7 best NAS client apps for Android
1. Solid Explorer — best universal NAS client
Solid Explorer is the pick if you want one app that works with any NAS. It speaks SMB1 through SMB3, FTP, SFTP, FTPS, WebDAV, and a wide list of cloud providers. The dual-pane interface is the most desktop-like file manager on Android, and the built-in media player covers most NAS streaming needs.
Where it falls short: Paid app after the trial. Some cloud plugins are separate purchases. Photo backup is not a first-class feature.
Pricing:
- Free: 14-day trial
- Paid: One-off purchase, with optional cloud plugins
Platforms: Android
Bottom line: The Solid Explorer for NAS workflow is the cleanest on Android. Worth the one-off price.
2. Cx File Explorer — best free universal client
Cx File Explorer covers the same ground as Solid Explorer for free. SMB, FTP, SFTP, WebDAV, plus the major cloud providers and OTG storage. The free tier has ads in the file picker, not in the file viewer, which makes the in-app advertising tolerable during real work.
Where it falls short: Polish lags Solid Explorer. SMB performance on multi-gigabyte transfers occasionally stalls and needs a retry.
Pricing:
- Free: Full app, ad supported in select menus
- Paid: Ad removal as an in-app purchase
Platforms: Android
Bottom line: Cx File Explorer is the free pick. Solid Explorer pays back its price in polish, but Cx covers the use case.
3. Synology DS file — best file browser for DSM
Synology DS file is the official browser for files on a Synology NAS. It handles QuickConnect out of the box, supports HTTPS with custom certificates, and streams audio and video files in-app. The two-factor flow lines up with DSM’s own settings.
Where it falls short: No photo backup. The UI has been refreshed but still looks dated next to third-party file managers.
Pricing:
- Free: Full app
- Paid: N/A
Platforms: Android, iOS
Bottom line: Install DS file on day one if you run a Synology NAS. It is the lightest way to grab files.
4. Synology Drive — best for Dropbox-style sync from a Synology
Synology Drive turns a Synology NAS into a private Dropbox. The Android client handles automatic photo backup, two-way folder sync, and the Drive desktop apps mirror the same shares from a laptop. The shared link UI is the closest a self-hosted setup gets to Dropbox or Google Drive.
Where it falls short: Requires the Synology Drive Server package on the NAS. Some advanced features depend on a recent DSM release.
Pricing:
- Free: Full client
- Paid: N/A
Platforms: Android, iOS, Windows, macOS, Linux
Bottom line: Pair this with a Synology NAS and you can cancel a paid cloud sync service.
5. Synology DS finder — best for discovery and admin
Synology DS finder is the lightweight admin companion. Discovery on the LAN, basic health checks, reboot and shutdown, and quick links to DSM Web. It is not a file browser, it is the app you keep on the home screen when you want to glance at the NAS rather than open it.
Where it falls short: Limited feature set, no file management. Notifications can be noisy if you have a busy NAS.
Pricing:
- Free: Full client
- Paid: N/A
Platforms: Android, iOS
Bottom line: Install DS finder as the glance-at-the-NAS shortcut. Pair with DS file for actual file work.
6. QNAP Qfile Pro — best for QNAP owners
QNAP Qfile Pro is the official browser for QNAP NAS files. It supports myQNAPcloud, HTTPS, in-app streaming, and shared link generation. Qfile Pro replaced the older Qfile as QNAP’s recommended client.
Where it falls short: UI is functional rather than friendly. Setup with myQNAPcloud Link needs the right port and CloudLink configuration on the NAS.
Pricing:
- Free: Full client
- Paid: N/A
Platforms: Android, iOS
Bottom line: Default pick for QNAP owners. Qfile Pro is the most direct path to your QTS files from a phone.
7. Nextcloud — best for self-hosted setups
Nextcloud is the official Android client for the open-source Nextcloud server. Photo backup, calendar and contacts sync (with the DAVx5 companion), shared link management, and offline pinning all live in one app. Pair it with a Nextcloud instance on your NAS, on a VPS, or hosted with a provider.
Where it falls short: Setup is more work than vendor clients. Mobile performance on large libraries depends entirely on the server you run.
Pricing:
- Free: Open-source client and server
- Paid: Optional Nextcloud GmbH support for organisations
Platforms: Android, iOS, web, Windows, macOS, Linux
Bottom line: Nextcloud is the self-hosted pick. The client is mature and the server is yours to control.
How to pick the right one
Pick Solid Explorer or Cx File Explorer if you want one app for every NAS, share, and cloud you touch.
Pick Synology DS file and DS finder if you run a Synology NAS. Add Synology Drive if you want Dropbox-style folder sync.
Pick QNAP Qfile Pro if you run a QNAP NAS.
Pick Nextcloud if you run your own Nextcloud server. The Android client is the official path.
A practical setup for most readers: Cx File Explorer for ad-hoc browsing, the vendor client for your NAS brand, and Tailscale or a similar mesh VPN to reach the NAS from outside the LAN.
FAQ
What is the best NAS client for Android?
Solid Explorer if you can pay once for a vendor-agnostic file manager. Synology DS file or QNAP Qfile Pro if you run a vendor-specific NAS.
How do I access my Synology NAS from Android?
Install DS file or Synology Drive, sign in with your Synology account or QuickConnect ID, and connect over Wi-Fi at home. From outside, use QuickConnect, a port forward, or a mesh VPN like Tailscale.
Is the Nextcloud app free?
Yes, the Android client is free and open source. The Nextcloud server is also open source and free to self-host.
Can I stream video from my NAS to Android?
Yes. DS file, Qfile Pro, Solid Explorer, and Cx File Explorer all stream directly. For a polished UI on top of a media library, pair with a dedicated player like VLC, MX Player, or a Plex or Jellyfin server.
How do I back up Android photos to a NAS?
Synology Drive and Nextcloud handle photo backup natively. For a Synology NAS you can also use Synology Photos. Generic file managers do not auto-upload by themselves.
