Stop walking to the printer room. PandaWatch gives you live cameras, temperatures, filament status, and error alerts for every Bambu Lab printer you own — in one view, from anywhere. Sign in with your Bambu Lab account, Google, Apple or Facebook and you're done. No IP addresses, no port forwarding, no setup wizard. One machine or twenty — it all just works. KEY FEATURES ZERO-SETUP FLEET MONITORING Sign in and go. PandaWatch finds your printers automatically via your Bambu Lab account — no network setup. Several Bambu accounts? Add them all to one dashboard. APPLE WATCH APP A native watchOS app puts your fleet on your wrist — status, temperatures and progress at a glance, with watch-face complications. MULTI-PRINTER LIVE ACTIVITIES (PRO) The first and only app to put your entire print farm on your Lock Screen and Dynamic Island. PandaWatch Pro supports up to 20 printers at once, with layouts for 4, 8, 12, 16 and 20-printer fleets, and one-tap access to any camera feed. SMART AUTO-SORTING Active printers rise to the top of your dashboard, so your busiest machines are always front and center. SIRI & APP INTENTS Ask Siri which printer has red PLA, which ones are low on filament, or when the next print finishes — without touching your phone. AMS & FILAMENT DETAILS Tap any AMS slot for full material details: drying time, weight, remaining percentage, and more, straight from the Bambu API, with full color visualization. FLEET SCOUT Need the one loaded with red PETG? Fleet Scout filters your fleet by filament color and material in seconds. LIVE CAMERA DASHBOARD View your whole fleet at once with staggered loading and battery optimization. Hide overlay text, or go fullscreen with tap-to-dismiss controls. A1 and P1 owners can enable Camera Fast Mode for a higher-refresh feed. ADVANCED DIAGNOSTICS HMS error codes, temperatures, fan speeds and live layer progress. Dismiss an error per printer or across the fleet, copy a code, or browse the Code Explorer to see what each one means. If a camera won't connect, the app explains what to check on the printer. FILE BROWSER Browse your printer's SD card over FTPS. Preview 3MF files and images, and play back livestream captures. Supports X1, H2 and P2 series. HOME SCREEN WIDGETS Widgets update in the background so your home screen always shows current status, and Fleet Health gives an at-a-glance overview of everything. Filter by filament color, choose which printers appear, and tap to jump straight in. IPAD DASHBOARD A proper desktop-class layout that uses the extra screen space — not a stretched phone view. Leave it running on a shelf as a dedicated monitoring display. AVAILABLE IN 10 LANGUAGES English, German, Spanish, French, Italian, Japanese, Korean, Portuguese, Brazilian Portuguese and Simplified Chinese, with translated printer error messages. Bambu Lab accounts in the China region are fully supported. ACCESSIBILITY VoiceOver support across printer cards, camera feeds, AMS swatches and progress bars. Transitions respect Reduce Motion. PRICING The core app is free — not "free for 3 days" free, but actually free for unlimited printers, forever. Cameras, diagnostics, widgets, Siri, Fleet Scout and AMS details — no fleet size limit, no cost. The one paid feature is multi-printer Live Activities on your Lock Screen. Up to two printers is free; PandaWatch Pro unlocks up to 20 at once for a one-time $3.99 — no subscription, no expiry. Fleet size stays unlimited either way. SUPPORTED MODELS Compatible with the entire Bambu Lab family: X1 Carbon, X1E, P1S, P1P, A1, A1 Mini, H2, P2 and X2D series. Note: Camera streaming and file browsing need a local network connection. Cloud monitoring works anywhere.

Some notifications matter more than others. Bell Alerts lets you give each one its own sound — so you know what just happened without even looking at your phone. Create a bell, share its code, and ring it. Everyone you've shared it with gets the alert instantly — each on their own phone, with the sound they picked. Dinner's ready, the dog's at the door, the meeting's starting: make it a bell. MAKE IT YOURS • A different sound for every bell — a dozen original tones to choose from • Per phone: you pick your sound, your family picks theirs • Vibrate-only or mute any bell, anytime • 11 app icons to match your style SEND A BELL IN A TAP • Create a bell — it gets its own private, unguessable code • Share the code; anyone who adds it is subscribed • Ring it from the app — or straight from a Home Screen widget, without opening anything • Changed your mind? "Oops" un-rings it — the alert crosses itself out everywhere STAY ON TOP OF IT • Recent rings at a glance, with timestamps — canceled ones clearly marked • A Home Screen widget shows the latest bells the moment they ring • Disappearing alerts tidy themselves up after a time you set PRIVATE BY DESIGN • No account, no sign-up, no tracking • Bells are private codes — only the people you share them with get the rings • Verified on device with App Check; standard encryption only FOR POWER USERS Bell Alerts can also receive alerts from your own internet server — the same bring-your-own-server idea as the open-source app ntfy. Send a notification from any script or service you run and it arrives as a custom bell on every subscribed phone. It's a software integration over the internet; no extra hardware or accessory is involved. Setup guide included. Make every alert sound like what it is.
