## What is KlippBoy?

KlippBoy is a native client for 3D printers running Klipper. It connects to Moonraker, the same API used by Mainsail and Fluidd, and keeps all your printers at hand on iPhone, iPad and Mac.

ALL YOUR PRINTERS AT ONCE
Every printer stays connected and the list shows each one's state, progress and temperatures at a glance. If a printer goes offline, KlippBoy reconnects on its own.

THE CURRENT PRINT
Thumbnail, progress measured on the actual G-code, finish time, remaining time, layer and filament used. Pause, resume or cancel with a tap, and print the last file again when it's done.

LIVE ACTIVITY
Follow your prints on the Lock Screen and in the Dynamic Island, with a progress bar and a countdown to the finish time.

TEMPERATURES AND CAMERA
A chart with the last 10 minutes of every heater and sensor, and targets you can set with a tap. Watch the printer's webcam, full screen if you like. It starts paused to save bandwidth.

FULL CONTROL
Move and home the axes, run quad gantry level or Z tilt, extrude and retract, change speed and flow, and control fans, outputs, filament sensors, power devices and your macros. The emergency stop is always one tap away.

FILES, HISTORY AND CONSOLE
Browse your G-code by folder with thumbnails and slicer details, upload new files, print or delete them, and check your print history. The console shows Klipper's responses and lets you send any command.

DESIGNED FOR APPLE DEVICES
Built in SwiftUI, with light and dark mode, English and Spanish, and layouts for iPhone, iPad and Mac.

NOTIFICATIONS
With the app closed, KlippBoy can tell you when a printer stops on its own, hits an error or finishes. The printer needs a bridge such as Node-RED to send its events.

WEB SERVER
Turn on KlippBoy's web server and open its address in the browser of a TV, a computer or any other device to see all your printers at once, with their state, progress and camera. Each screen picks how many cards to show, their order and a filter.

PRIVATE BY DESIGN
No accounts, no ads, no tracking. Your printers' data stays between the app and your printers, unless you turn on push notifications. KlippBoy also sends usage statistics and crash reports to improve the app, and you can turn them off in Settings.

No printer at hand? Add the demo printer to try every feature.

KlippBoy is an independent app and isn't affiliated with the Klipper or Moonraker projects. Requires a printer running Klipper with Moonraker.

## Version history (last 5 releases)

### 1.2.2 — 2026-11-06

Upload and print
When you upload a G-code file, choose whether to just upload it or upload it and start printing right away.

Also, each printer remembers its tab: when you open the app, even from a notification, it stays where you left it.

### 1.2.1 — 2026-11-01

Zoom on the camera
In full screen, pinch to zoom in and drag to move around the picture. Double-tap to get closer to a spot, and double-tap again to see the whole picture.

Also in this version, the summary at the top of the web server page no longer gets cut off.

### 1.2 — 2026-10-30

Printer notifications
With the app closed, KlippBoy can tell you when a printer stops on its own, hits an error or finishes, and keep the Live Activity up to date. Turn them on from each printer's … menu, under Notifications. The printer needs a bridge such as Node-RED to send its events.

Web server
Turn on the web server and open its address in the browser of a TV, a computer or any other device to see all your printers at once, with their state, progress and camera. Each screen picks how many cards to show, their order and a filter. On iPhone and iPad it works with the app open. You'll find it in Settings.

### 1.1 — 2026-10-29

Why it stopped
When a print pauses, is cancelled or fails, KlippBoy now tells you why: in the job card, in the printer list, in the Live Activity and in the widget.

On the Snapmaker U1, the most common reasons are spelled out: spaghetti detected, dirty nozzle or bed, leftovers on the bed, an extruder out of filament, tangled filament, a toolhead that failed to park, a G-code file that can't be read, a purifier fan fault or an enclosure that's too hot. On other Klipper printers you'll see Klipper's own message.

Arrange your dashboard
Put the cards in the order you want: Print Job, Temperatures, Filaments and Camera. On the dashboard, open the … menu and choose Arrange Dashboard.

Better time estimates
When the G-code includes the slicer's progress (M73), the percentage, the progress bar and the time remaining now follow it, adjusted to how fast your printer is really going. Parts with a large base and a thin top no longer show hours too many.

Small fixes
The finish time on the Lock Screen and in the widget follows your iPhone's 12- or 24-hour setting, and 100% no longer gets cut off in the small widget. In dark mode, the Live Activity and the widget use the grey of the KlippBoy icon.
