If you regularly use your phone to project or print patterns, things are about to get a lot easier. Two new apps have just launched as phone-first alternatives to Pattern Projector — and depending on your setup, one of them might genuinely change how you sew.
This post is aimed at sewists who are already using a projector (or at least already familiar with Pattern Projector). If you’re brand new to projector sewing, start with my beginner playlist linked in the video description first. And if you’re ready to get set up properly, my course, Complete Projector Confidence, walks you through exactly how to choose a projector, get connected, and start cutting out your first patterns.

A Quick Recap: Where We’ve Been
For those who were sewing before Pattern Projector existed, you’ll remember the days of cobbling together manual calibration — fiddling with PDF viewer zoom levels and nudging the projector into position by trial and error. Pattern Projector changed all of that.
What makes it special:
- Completely web-based — open it in a browser, or add it to your device. Nothing to install.
- Free, open-source, and community supported, with active ongoing development.
- Corner-drag grid calibration — a huge upgrade from manual guesswork.
- Built-in multi-page stitching, so you can load a PDF or SVG pattern and stitch multi-page files together for projection.
- Core editing tools: flip, rotate, mirror, move, and invert collars.
The catch? Pattern Projector was designed around desktop and laptop use. Your projector connects to your computer, and you control everything from that screen. It can run on a tablet or phone since it’s web-based, but it wasn’t optimized for it — and it can feel laggy or clunky when you’re trying to calibrate or move a pattern from a small screen.
That’s exactly the gap the next two apps were built to fill.
Why “Phone-First” Matters
Not everyone has a laptop in their sewing room, or a computer they want to haul back and forth to the cutting table. But your phone? It’s already in your hand.
The idea behind both IntelliSew and Sewsy is simple: what if your entire projector sewing workflow could run from the device you’re already holding — no walking back and forth to a laptop, no compromise on comfort. Each app takes a slightly different approach, so here’s a first look at both. (I’ll be doing a deeper dive into each in future videos, so subscribe if you don’t want to miss those.)
IntelliSew: A Direct Phone-First Alternative
IntelliSew follows the same core workflow as Pattern Projector — calibrate your projector, load your PDF, and start cutting — but the entire experience is built around the phone screen.
The standout feature right now is AI-calibration, currently in beta. Instead of dragging a grid into place, your phone recognizes the cutting mat and calculates the projection alignment automatically. It’s about 95% accurate at this stage, and it should only improve as more data comes in. Even in beta, it’s an exciting glimpse at where phone-based calibration is headed. (And if you’d rather stick with the familiar drag-and-drop grid, that option is still there too.)
IntelliSew handles standard PDF patterns, and letter-sized PDFs can be stitched in the app. It uses a two-screen approach: what you see on your phone is a simplified view for readability, while the actual projection is what gets calibrated and displayed. Think of your phone as a remote control for the projection — you’re directing what happens, while getting a clear view of your pattern without needing to squint at the projected image itself.
IntelliSew has a solid set of free features, with more advanced tools reserved for Pro subscribers.
Who it’s for: Sewists ready to move fully to a phone-based workflow, especially anyone excited about where auto-calibration and upcoming advanced pattern features are headed.
Sewsy: Projection and Printing in One App
Sewsy takes a different angle. It does everything Pattern Projector does — calibrate and project patterns from your phone onto your cutting mat — but it also supports printing layered patterns directly from your phone.
That second part matters more than it might sound. If you print patterns, you know how hard it’s been to find a phone-based PDF reader that correctly recognizes pattern layers and prints them accurately. Getting that wrong on a 20+ page pattern is a frustrating (and expensive) mistake. Sozy solves that gap.
That makes Sewsy a genuinely flexible, complete phone-based pattern solution — project when you want to, print when you need to, all from the same app. It’s also a strong pick if you’re not fully committed to projection yet, or if you’re introducing someone new to digital pattern sewing and want one tool that covers both bases.
On the projection side, Sewsy works much like you’d expect: touch controls for moving pieces, flip, mirror, and the rest of the essentials for a smooth projecting experience.
Who it’s for: Sewists who want flexibility between printing and projecting, or anyone easing into digital pattern sewing without committing to projection-only just yet.
Bringing It All Together
- Pattern Projector — the original. Free, browser-based, best on a computer. Made calibration accessible and combined it with multi-page pattern stitching.
- IntelliSew — phone-first, with beta auto-calibration and more advanced features on the way. Built for sewists ready to work entirely from their phone.
- Sewsy — phone-first, with both projecting and printing built in. Best for flexibility, or for anyone still deciding how far into projection they want to go.
All three apps support standard PDFs, and all share the same goal: getting your pattern from file to fabric as smoothly as possible. The real difference comes down to your workflow and the hardware you want to build around.
Pattern Projector opened the door for a lot of us to leave manual calibration behind, and now developers are building on that momentum with phone-first interfaces, auto-calibration, and print-and-project flexibility. That’s a genuinely good thing for the whole sewing community.
If you’ve already tried IntelliSew or Sewsy, I’d love to hear about it — drop a comment and let me know what you’re using, what you love about it, and what features you’re still hoping to see. And if you’re brand new to projector sewing, check out my beginner playlist to get up to speed.
Happy sewing!
