Star Debug is an alternative tool to manage your Starlink devices. Currently, it supports: - Decode and view DebugData json copied (or saved to file) from the official Starlink app or web panel. - Initiate basic operations with the dish: Reboot/Stow/Unstow/GPSon/off and with the router: reboot and basic wifi setup (if applicable). - View telemetry available in DebugData, but updated from Starlink online: statuses, alerts, basic stats, current configurations, etc. - Create and share DebugData-compatible json data. - Check the internet connection in place within the app. This application was created as part of the volunteer initiative "Narodnyi Starlink" for the needs of people who care about the availability of communications even in the places where the russian aggressor tries to turn cities into ashes.

MQTTAnalyzer's advantage is update cadence (every 5 days vs every 2 months) and ratings volume (22 vs 5). On price, ads, in-app purchases and monetization model there is nothing between them.
