RAyTools 3 is installation technician’s best friend and a result of our continued effort to build upon the success of previous generation of the app. RAyTools is a modern mobile and tablet app simplifying planning, deployment and maintenance of RAy links. RAyTools has got 3 main features: • Link Calculator supporting all our links and antennas, giving you the same quality of results as our much-loved website calculator; • Antenna Alignment for voltmeter-free installation, including real-time RSS plot and acoustic output; • Link management access. Next time, leave your heavy gear at home and align antennas only using your phone! Requirements: • RAy3 with firmware version 2.0.11.0 or higher installed – see Download section on http://www.racom.eu/ray-downl-eng; • WiFi module plugged in to RAy unit – see http://www.racom.eu/wifi2-eng; • WiFi enabled in RAy management – see chapter “USB Accessories” in user manual; • Smartphone or tablet connected to RAy unit by WiFi. Use of device location: Your location may be used if the user decides to use the feature to automatically input coordinates into link calculation. It is shared anonymously with Google Maps Elevation API service to request terrain height map of the link. No information is saved outside your device.

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.

Verdict
The clearest difference is in-app purchases: RAyTools at none against Moonraker Buddy's 1. RAyTools also leads on iOS requirement (15.1 vs 17.2). Moonraker Buddy's advantage is update cadence (every 2 weeks vs every 4 months). On price, ads and device support there is nothing between them.
