NAS Guard

NAS Guard – keep an eye on your TrueNAS, right from your iPhone.

NAS Guard connects to your TrueNAS server over the encrypted WebSocket API (JSON-RPC) and shows your system's status and health clearly and in real time.

MONITORING (free)

• Dashboard: CPU, RAM, network throughput, load
• Pools & datasets: capacity, status, scrub state
• Disks: health, temperatures, ZFS errors (read/write/checksum)
• Disk health forecast: drive health trend
• Apps/containers, VMs and services: running status
• View data protection: snapshots, Cloud Sync, Replication, Rsync, TrueCloud, Cron
• Shares: SMB, NFS, iSCSI, NVMe-oF
• Security & certificates, network interfaces, UPS
• Your NAS system alerts

FILES & PREVIEW (free)

• Browse your NAS file system folder by folder, with size and modification date, folders first, and pull-to-refresh.
• Rich Quick Look preview: photos (JPEG, PNG, GIF, HEIC, WebP, TIFF, BMP), PDF, plain text and code (JSON, XML, YAML, shell, Python, Swift, JS/TS, SQL and more) and office documents (Word, Excel, PowerPoint, Pages, Numbers, Keynote).
• Built-in audio player (MP3, FLAC, WAV, AAC, M4A and more) with a live spectrum and waveform visualizer.
• Video: MP4, MOV and M4V play directly (stream-optimized files stream without a full download).

DO MORE WITH THE OPTIONAL AGENT (free, self-hosted) The NAS Guard Agent is a small container you install on your TrueNAS in one tap – just pick a pool and a port, no shell or compose editing. It keeps itself up to date automatically and adds:

• Real-time alerts: get notified about outages and important events even when the app can't reach your NAS directly – faster and more reliable than background polling.
• Live Activities (Control Pack): follow long-running jobs (scrub, resilver, replication, Cloud Sync, Rsync) live on the Lock Screen and Dynamic Island, updated in the background even when the app is closed.
• Full media streaming: play video of any size instantly with no download, and open containers Apple can't handle natively (MKV, AVI and more) via on-the-fly HLS remux – with hardware-accelerated transcoding on Intel/AMD GPUs when available.
• Runs entirely on your own NAS.

IN-APP PURCHASES – honest and transparent

Free:

• 1 server profile
• Full read/monitoring feature set, files & preview, and the optional agent

Unlimited Servers (one-time purchase):

• As many server profiles as you like
• Background monitoring of all servers (free: only the selected one)

Control Pack (one-time purchase) – unlocks all control features:

• Power: shut down, reboot and wake your NAS via Wake-on-LAN
• Apps/containers: start, stop, redeploy, update (single & all)
• VMs: start, stop, restart
• Services: start/stop
• Pools: start/stop scrub
• Datasets: create, edit, delete, lock/unlock
• Shares: create and enable/disable (SMB, NFS, iSCSI, NVMe-oF)
• Data protection: run/abort/toggle Snapshot, Cloud Sync, Replication, Rsync, TrueCloud and Cron tasks
• Live Activities (with paired agent)
• AI assistant: ask questions about your NAS – fully on-device via Apple Intelligence, no cloud

Tip (optional): small, medium or large support for development. Unlocks no features.

GOOD TO KNOW

• Without the Control Pack the app is fully usable read-only – you won't control anything by accident.
• Wake-on-LAN must be enabled on your NAS first (BIOS/UEFI + network card) and only works on your local network, not remotely.
• The AI assistant requires an Apple Intelligence-capable device with Apple Intelligence enabled.
• All purchases are one-time – no subscriptions.
