If you search the App Store for “printer app,” you get two completely different worlds. One world is document printing — sending PDFs, photos, and emails to your inkjet or laser printer over Wi-Fi. The other is 3D printing — monitoring a spool of PLA as it builds a phone stand layer by layer over four hours. This guide is about the second world. The apps here manage 3D printers, not paper printers, and confusing the two categories leads to bad downloads and wasted time.

We cover the companion apps worth installing for popular 3D printer brands, what they actually do on your phone, and where their limits are. If you landed here looking for help printing documents from your iPhone, see our best printer apps guide and print from phone guide instead — that is a different topic with different tools.

What 3D Printer Apps Actually Do

A 3D printer companion app is not a replacement for your slicer. It does not turn your phone into a full 3D design workstation. Instead, these apps handle a focused set of tasks around an already-configured printer.

Remote monitoring is the most common reason people install these apps. A 3D print can run for hours. With a companion app, you check progress from the couch, get a notification when the job finishes, or see an alert if the print fails mid-run. Many apps include a live camera feed if your printer has a webcam attached.

Print job control lets you start, pause, resume, and cancel prints from your phone. This is useful when you realize a model is detaching from the bed and want to stop before filament wastes itself across the build plate.

Printer settings adjustment covers temperature tweaks, fan speed changes, and filament loading or unloading on some models. You are not redesigning the model — you are adjusting the machine while it runs.

Basic slicing appears in a few newer apps, particularly from Bambu Lab and some Creality models. These can prepare simple models for printing without opening a computer. For complex models with supports, custom infill, or fine tolerances, you still need desktop slicer software.

Firmware updates and maintenance walk you through calibration routines, belt tensioning reminders, and firmware flashes that keep the printer running reliably.

None of these apps send a Word document to an HP inkjet. If you need that, you want AirPrint and a document print app — not a 3D printer companion.

Manufacturer Apps: Start Here

The most reliable 3D printer apps come from the company that made your hardware. They are updated when firmware changes, tested against specific models, and cover setup from unboxing through daily use.

Bambu Handy (Bambu Lab)

Bambu Lab printers — the X1 Carbon, P1S, A1, and related models — use Bambu Handy as their primary mobile interface. The app handles printer setup over Wi-Fi, sends print jobs from Bambu Cloud or a local network, and provides real-time monitoring with camera support on equipped models.

Bambu Handy includes a built-in model library with free and paid designs, basic slicing for straightforward prints, and notifications for job completion or failure. The integration is tight because Bambu controls both the hardware and software stack. If you own a Bambu printer, this is the app to install first.

Creality Cloud

Creality’s app covers the Ender series, CR models, K1 printers, and other Creality hardware. It offers remote monitoring, print job management, a model marketplace, and slicing for supported printers. Setup can be more involved than Bambu because Creality’s product line is broader and older models vary in connectivity features.

Creality Cloud works best with printers that have Wi-Fi capability built in or added through a Creality Wi-Fi box. Older USB-only Ender models without network access cannot be controlled from your phone regardless of which app you install.

Prusa Connect / PrusaLink

Prusa Research provides Prusa Connect for monitoring printers equipped with PrusaLink — a Wi-Fi module on the MK4, MK3.9, XL, and Mini+ with the upgrade installed. The app shows print progress, temperatures, and a webcam stream. Job submission still typically happens through PrusaSlicer on a computer, with the app serving as a remote dashboard.

Prusa’s approach is more conservative than Bambu’s cloud-first model. The printer and app communicate over your local network, which appeals to users who prefer keeping print data off external servers.

Anycubic and Elegoo Apps

Budget resin and FDM printer brands Anycubic and Elegoo offer companion apps for their networked models. Features vary by printer generation — newer Kobra, Photon, and Saturn models with Wi-Fi get more app support than older USB-only units. Check the app listing for your exact model number before assuming compatibility.

These apps cover monitoring, file transfer for printers with onboard storage, and basic settings. They are functional rather than polished, but they work for the price point these printers occupy.

Third-Party Apps for OctoPrint and Klipper

If you run OctoPrint on a Raspberry Pi or use Klipper with Moonraker, manufacturer apps may not apply. The community has built solid mobile frontends for these setups.

OctoApp

OctoApp connects to your OctoPrint instance over the local network or through a VPN if you have remote access configured. It displays print progress, controls job execution, shows webcam feeds, and manages files on the Pi. The interface is cleaner than opening OctoPrint’s web UI on a phone browser.

Setup requires OctoPrint already running and accessible on your network. Generate an API key in OctoPrint’s settings and enter it in OctoApp during initial configuration.

Printoid for OctoPrint

Printoid is a long-established OctoPrint client for Android with a feature-rich Pro version. It supports multiple printer instances, custom G-code commands, filament management plugins, and detailed temperature graphs. iPhone users have fewer OctoPrint app options, making OctoApp the more common iOS choice.

Fluidd and Mainsail (Browser-Based)

Klipper users often run Fluidd or Mainsail as web interfaces. These are not native apps but responsive web dashboards that work in a phone browser. Bookmark the local URL on your phone’s home screen and you get an app-like experience for monitoring Klipper printers without installing anything from the App Store.

Slicer Apps vs. Companion Apps

Understanding the distinction prevents frustration.

Slicer software — PrusaSlicer, Ultimaker Cura, Bambu Studio, Simplify3D — takes a 3D model file (STL, 3MF, OBJ) and converts it into G-code instructions your printer understands. Slicing involves choosing layer height, infill percentage, support structures, print speed, and material profiles. This is computationally intensive and benefits from a large screen and mouse input. Most people slice on a desktop or laptop.

Companion apps run alongside the slicer. You slice on your computer, send the G-code to the printer (via SD card, USB, Wi-Fi, or cloud), and then use the phone app to monitor and control the running job. Some newer ecosystems blur this line by adding basic slicing to the app, but the workflow split still exists for anything beyond simple prints.

If someone tells you to “just use your phone” for the entire 3D printing workflow, they are either using a very integrated ecosystem like Bambu Lab or oversimplifying the process.

What About Document Printing Apps?

This is where honesty matters. Smart Printer is a useful iOS app for printing documents, photos, and scanned papers to AirPrint-compatible inkjet and laser printers. It is not a 3D printer app. It does not send G-code, monitor nozzle temperatures, or manage filament spools.

Smart Printer is not affiliated with any 3D printer manufacturer or document printer brand. It uses Apple’s AirPrint protocol to connect to Wi-Fi printers on your network. If you need to print a PDF, email, or photo on paper, it is worth considering alongside the options in our best printer apps roundup. If you need to monitor your Ender 3, download Creality Cloud instead.

The same separation applies to HP Smart, Canon PRINT, and Epson Smart Panel — these are document printer apps, not 3D tools. Keeping the categories straight saves you from one-star reviews on the wrong app listing.

Features Worth Comparing Before You Install

Not all 3D printer apps are equally capable. Evaluate them on these criteria.

Model compatibility. An app designed for Bambu Lab printers will not control a Creality Ender 3. Verify your exact printer model appears in the app’s supported devices list.

Local vs. cloud connectivity. Bambu and Creality route some features through cloud servers. Prusa and OctoPrint setups can work entirely on your local network. If you print proprietary designs and care about file privacy, local-only communication may matter.

Camera support. Remote monitoring is far more useful with a live video feed. Check whether the app supports your printer’s camera — built-in, USB webcam via OctoPrint, or not available.

Notification reliability. A print failure alert at 2 AM is only helpful if the notification actually arrives. Read recent app reviews focusing on notification delivery, especially on iOS where background app restrictions can interfere.

Slicing capability. If you want phone-only workflows, confirm the app can slice your typical model formats. If you always slice on a computer, this feature is irrelevant.

Offline functionality. Some app features break without internet if they depend on cloud services. Local network control through OctoPrint or PrusaLink tends to be more resilient.

Setting Up a 3D Printer App: General Steps

While each app differs, the setup pattern is similar across brands.

Connect your 3D printer to Wi-Fi first. Most apps assume the printer is already on your network. Use the printer’s touchscreen, the manufacturer’s web interface, or a USB Wi-Fi adapter depending on your model.

Download the correct app from the App Store or Google Play. Search for the manufacturer’s name plus your printer model to avoid third-party apps with similar names.

Create an account if required. Bambu and Creality apps typically need accounts for cloud features. OctoPrint apps need the Pi’s local IP address and an API key.

Pair the app with your printer. This usually involves scanning a QR code on the printer’s display, entering a PIN, or selecting the printer from a list of devices on your network.

Send a test print. Start with a small, pre-sliced model included with the printer or app — a calibration cube or Benchy — to confirm the full pipeline works before committing to a multi-hour print.

If your printer lacks Wi-Fi entirely, no app will help until you add network connectivity through an upgrade module, OctoPrint on a Pi, or a new printer with built-in wireless.

When a 3D Printer App Is Not Enough

Companion apps cover daily monitoring and control, but they do not replace these essentials.

A proper slicer on a computer for any model more complex than a basic shape. Phone slicing is improving but is not yet a full replacement for desktop tools.

Physical maintenance — bed leveling, nozzle cleaning, belt tensioning, lubrication. No app performs these tasks. Some apps include guided calibration routines, but your hands still do the work.

3D modeling software if you are creating original designs. Sculpting, CAD, and mesh repair happen in apps like Fusion 360, Blender, or Tinkercad — not in printer companion apps.

Document printing setup for the paper printer sitting next to your 3D printer on the desk. That workflow runs through AirPrint. Our print from iPhone guide and print from Android guide cover it.

Choosing the Right App for Your Setup

Match the app to your hardware and workflow.

Bambu Lab owners: Install Bambu Handy. It is the most integrated mobile 3D printing experience available right now.

Creality owners with Wi-Fi models: Install Creality Cloud. Older USB-only printers need hardware upgrades first.

Prusa owners with PrusaLink: Install Prusa Connect for monitoring. Keep slicing in PrusaSlicer on your computer.

OctoPrint users: Install OctoApp (iOS) or Printoid (Android). Configure with your Pi’s API key.

Resin printer owners: Use the manufacturer’s app — Anycubic, Elegoo, or Phrozen — for printers with network features.

Document printing from your phone: Skip 3D printer apps entirely. Use AirPrint or a document app like Smart Printer for paper output, and consult our best printer apps guide for a full comparison.

3D printer companion apps earn their place on your phone through monitoring and convenience, not by replacing your computer entirely. Install the one that matches your hardware, keep your slicer on the desktop, and use the right tool when you need to print something on paper instead of plastic.
