I’m a solo dev and I got tired of not having a good iOS app to manage my self-hosted media stack, so I built one.
Quartermaster connects to Radarr, Sonarr, SABnzbd, NZBGet, qBittorrent, Jellyseerr, Overseerr, Jellyfin, Emby, Lidarr, Prowlarr and Bazarr. Manage your library, approve requests, watch your download queues, see active streams — from your phone.
The part I care about most: it’s pure client-side. No backend, no analytics, no accounts. Your server credentials are stored on-device in the iOS Secure Enclave and the app only ever talks to the servers you point it at. Nothing leaves your phone.
It’s in TestFlight beta now and I’m looking for testers — especially if you run qBittorrent or a less common setup. Free to test.

Happy to answer anything about how it works.



How does this compare to Helmarr?
Helmarr’s genuinely good and more established than me, it covers more services right now, so if it does what you need it’s a solid pick. Mine’s newer and more focused. I’m a solo dev building it around feedback like this, so it’ll move fast. Honestly happy to be compared, competition’s good for everyone.
What exactly is this solution providing that just having a safari shortcut to the service doesn’t? Like, what’s justifying this costing money? It doesn’t sound like it’s doing anything for the user that isn’t already equally easy and 100% free.
Edit: sorry if it comes off as flippant, I genuinely just don’t understand the purpose of this.
Fair question. A Safari shortcut just opens each service’s web UI one at a time. This pulls all your services into one native app, so you see downloads, requests, library and streams together, with proper iOS navigation, widgets, and stuff the web UIs don’t do well on a phone. If the web UIs work fine for you, that’s genuinely valid, this is for people who want one tidy native place for the whole stack :)
