I created Moonraker Buddy after flashing my Flashforge printer with Zmod and finding that i did not like any of the available apps. I have tried to create a clean, easy to use and low cost app that allows you to monitor multiple Moonraker / Klipper printers at the same time. The free version allows you to add a single printer with limited funuctionality. For a small in-app purchase you can unlock the ability to add multiple printers and full functions. KEY FEATURES — Live dashboard with progress, temperatures, fan speeds, and current layer — Webcam streaming with pinch-to-zoom, rotation, and snapshot capture — Live Activity on the lock screen and Dynamic Island showing elapsed and "done by" times — Smart notifications for print complete, errors, pauses, cancellations, filament runout, temperature deviation, and Klipper shutdown — Multi-printer support with groups — monitor a whole farm from one app — Interactive 3D bed-mesh visualisation with drag-to-rotate isometric view — Browse and start G-code files directly from the app — Run macros, control fans, lights, and power devices — One-tap calibration routines — Network discovery — find printers on your WiFi automatically via Bonjour — QR-code scan to import Moonraker API keys — Background polling so you get notified about issues even when the app is closed — Print history with thumbnails and filament usage — Demo mode so you can try everything before connecting a real printer — Spoolman integration — Octoeverywhere integration allowing remote access from anywhere PRIVACY FIRST Printer addresses, API keys, and print history never leave your iPhone unless you explicitly use the in-app feedback form. No analytics, no tracking. Requires a 3D printer with Moonraker reachable on the same WiFi network as your iPhone or iPad.
