About

Tower

Features
Read full description

Tower is a native iOS client for your Unraid server. It talks straight to your own machine — there is no account to create, no service in the middle, and nothing of yours on anybody else's computer. Tower does not provide, host, stream, or download any media. It is a remote management interface for a server and the applications you already run on your own hardware. A search you start runs against the indexers you configured on that server, and the result goes to your own download client. No media file is ever downloaded to your phone. YOUR SERVER, AT A GLANCE • Array status, capacity, and parity state the moment you open the app • CPU, memory, uptime, per-disk temperature and usage • User shares with their allocation settings, disks and the pool they live on • Notifications and system logs without reaching for a terminal DOCKER AND VIRTUAL MACHINES • Containers with real state — start, stop, restart, pause, resume • Per-container logs, ports, and the volumes actually mounted • Virtual machines, including force stop when a guest stops listening • A container and the service it runs, cross-linked both ways CONTROL THE SERVICES YOU RUN ALONGSIDE IT Tower drives the self-hosted applications on that server too, each through its own local API, and each appearing only once you have given Tower its address: • Sonarr, Radarr and Lidarr: library, calendar and history; add, edit or remove a movie, series or artist; start a search and send a result to your own download client • NZBGet: queue, progress and speeds; pause, resume or remove a download; retry from history • Prowlarr: indexer health, and adding, testing, enabling and removing indexers • Bazarr: subtitle status, and a manual subtitle search your server carries out • Overseerr: search, request, and approve or decline what is waiting on you • Tautulli: who is watching what, with bandwidth and transcoding at a glance Tower sends the instruction; the applications on your own server do the work. BUILT FOR iPHONE AND iPAD • Adaptive layouts with proper split views on iPad • Dynamic Type, semantic colors, and system controls throughout • Light and dark, or pin whichever you prefer PRIVATE BY CONSTRUCTION • Connects directly to your own machines over your own network • Every API key is stored in the iOS keychain and sent only to the server it belongs to • No accounts, no analytics, no ads, no telemetry, no backend of ours TRY IT FIRST • A built-in demo mode runs the whole app against sample data — every service, every screen — so you can see everything before pointing it at a real machine Tower requires an Unraid server with its GraphQL API enabled, and network access to it from your device. Service features require the corresponding application to be running and reachable on your network. Tower is an independent project, and is not affiliated with or endorsed by Lime Technology, Inc., Plex Inc., or the projects whose APIs it speaks.
