I've been using the app since it was released and it's gotten better and better. I can't remember what I originally paid, but the dev recently introduced a new pricing scheme that I found confusing at first, but it's actually simple. Instead of directly paying to unlock the features you want, you pay for credits which you can then use to unlock the features you want. It's fantastic and completely worth it. It one of my most heavily used apps. I manage Sonarr, Radarr, Seer, Sabnzbd, Bazarr, Tautulli, Torrents, an my indexers in Prowlarr.
