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.
