KlippBoy
Keep an eye on every print.
KlippBoy is a native Klipper client for iPhone, iPad and Mac. It connects to your printers through Moonraker and keeps all of them live at once: progress, temperatures, camera, files and controls.
Coming soon to the App Store
Free, with no account and no tracking.
From first layer to last
What Mainsail and Fluidd show you, made for the screen in your hand. And when you lock your iPhone, a Live Activity keeps counting down to the finish.
-
All your printers
Every printer stays connected. The list shows each one's state, progress and temperatures at a glance.
-
The print in progress
Progress measured on the actual G-code, finish time, layer and filament. Pause or cancel with a tap.
-
The camera
Watch the printer's webcam, full screen if you like. It starts stopped to save bandwidth.
-
Full control
Move and home, extrude, fans, outputs, macros and power devices. The emergency stop is always one tap away.
-
Files and history
Your G-code by folder with thumbnails, uploads, print history and a console for any command.
