Helmarr: iOS Companion for Sonarr and Radarr
Helmarr is an iOS companion app for Sonarr and Radarr, giving you a phone-shaped view of instances running on your own server.
What it is for
Most *arr interaction on a phone is checking rather than doing: did the episode grab, what is queued, what is releasing this week. Helmarr focuses on exactly that read-heavy workflow, presenting the calendar, queue, and history as native views rather than a compressed web page.
Setup
Point it at your instance URL and paste the API key from the application’s settings. As with any *arr client, keep the underlying services off the public internet and reach them over a VPN.
Choosing between iOS clients
The iOS *arr client space is unusually crowded: Helmarr, Ruddarr, LunaSea, and nzb360 (Android) all overlap. They differ mainly in how many services they aggregate and how opinionated the interface is. Helmarr sits at the focused end, which is a virtue if you only run Sonarr and Radarr and want something quick to read.
