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. NAS Guard is an independent project and is not affiliated with iXsystems or TrueNAS. ## NAS Guard Screenshots - [Screenshot 1](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/52/e6/d2/52e6d234-987c-e9a2-9832-fa85f62b157a/simulator_screenshot_FA9B7F44-244A-4FEA-9535-F0E4B3AEA00B.png/1206x2622.png) - [Screenshot 2](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/53/c1/a2/53c1a2e5-e0a4-37bc-c7c9-092564d5f599/simulator_screenshot_BF392587-EA9B-4E8D-B41C-686CE6ED3569.png/1206x2622.png) - [Screenshot 3](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/bf/a1/04/bfa10485-4b1b-b7af-ae7c-6f4f3182ceed/simulator_screenshot_43ED06FF-2AE4-42EE-90AB-438AAFDA71E4.png/1206x2622.png) - [Screenshot 4](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/5a/aa/b3/5aaab3dc-b743-5771-b917-90f8ed040376/simulator_screenshot_0C5371F1-8036-4E28-BAF2-CB5AE584A9A0.png/1206x2622.png) ## NAS Guard Rating Breakdown in Germany - 5 stars: 10 (83%) - 4 stars: 0 (0%) - 3 stars: 0 (0%) - 2 stars: 1 (8%) - 1 stars: 1 (8%) ## NAS Guard Reviews in Germany ### ***** "Tolle App!" Auch wenn ich das Control Pack nicht wirklich brauche (die Grundfunktionen reichen zum Monitoren absolut aus!), habe ich es mal erworben, um die weitere Entwicklung zu unterstützen. Mittelfristig wäre noch ein nativer iPad Support wünschenswert! -- oli792, 2026-04-27 ### ***** "Klasse App und toller Kontakt" Ich muss sagen, ich bin von der App begeistert! Sehr übersichtlich, gutes Design und praktisch alle wichtigen Funktionen auf einen Blick. Und das Beste ist, der Entwickler reagiert auf Ideen und Hinweise, ist super nett und versucht alle Wünsche einzubauen. Wirklich klasse! Herzlichen Dank dafür! -- Patrick0076, 2026-04-23 ### **--- "Only works with local ip" I only get a Connection when using the local host name „truenas.local“ but Connection fails when I try to connect using Tailscale vpn. Usually I can access my truenas web ui using the tailscale ip or host name when connected over tailscale vpn. But the app shows the error message „TLS error secure connection failed“. -- Sebas. Tian., 2026-04-07 ### ***** "Funktioniert" Die App macht alles was sie auch beschreibt. Außerdem kommen auch regelmäßig Updates und neue Funktionen. Kann ich empfehlen. -- Ricomitdreio, 2026-03-20 ### *---- "Nutzlos" Das einzige was man damit machen kann, ist Neustart und Abschalten. Dafür zahlt man 1 Euro. -- KugaBlanca, 2026-02-09 [View all NAS Guard reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## NAS Guard In-App Purchases | Item | Price | |------|-------| | Control Pack | €0.99 | | Unbegrenzte Server | €0.99 | --- ## About AppTail [AppTail](https://apptail.io) is a mobile app intelligence platform providing app analytics, ASO (App Store Optimization) tools, keyword tracking, competitor analysis, revenue estimates, and review monitoring for iOS App Store apps.
