Cut List Optimizer App: Using CutPlan on Mobile & Tablet
Yes, you can run a full cut list optimizer on your phone or tablet, and for most woodworkers a web app is the better choice over a native app store download. A mobile optimizer lets you count sheets at the lumber yard, keep a live cutting diagram next to the saw, and sketch a project from the couch before you touch a single board. This guide covers how to do it, when a native app actually makes sense, how to install a web optimizer to your home screen so it behaves like a real app, and the mistakes that cost people accuracy on a small screen. If cut list optimization itself is new to you, start with our complete guide to cut list optimization, then come back for the mobile workflow.
Why use a cut list optimizer on mobile?
The reason is almost always the same: the computer is in the office, and the work is happening somewhere else. A mobile optimizer removes the walk between planning and doing, and it removes the guesswork from the two moments that cost the most money, buying material and making the first cut.
At the lumber yard. You are standing in front of a stack of plywood and need to know how many sheets to buy. Enter your parts and the sheet size on your phone, run the calculation, and you have a real answer before it hits the cart. This is where mobile pays for itself. Overbuy by one sheet of 18mm birch ply and you have wasted 60 to 90 US dollars; come up one sheet short and you are making a second trip that eats an hour and a tank of fuel.
In the workshop. A tablet propped near the saw is a live reference to the cutting diagram. No squinting at a small printout, no walking across the shop, no losing the page under a pile of offcuts. You can pinch to zoom into a crowded corner of a sheet and swipe between sheets as you work through the stack.
On the go. Planning from the train, the couch, or a client's kitchen becomes practical when the tool runs in any mobile browser. Rough out a cut list, optimize, and see whether the project is even feasible with the material you had in mind before you drive anywhere.
In front of a client. If you build cabinets or furniture to order, showing the cutting layout on your phone earns trust fast. The client sees the material efficiency, understands why the quote says five sheets and not four, and watches their job break down into real parts.
Native apps vs web apps vs home-screen apps
Search "cut list optimizer" in the App Store or Google Play and you will find a handful of native apps. The best known is CutList Opt on iOS. Android has several, and quality varies a lot. Native apps have genuine strengths: they can run fully offline with no signal at all, they hook into the phone's notification system, and they follow platform design conventions so they feel at home.
The trade-offs are just as real. Native apps are platform-locked, so an iOS app will not run on your Android tablet or your Windows laptop. Fixes wait on app store review cycles. And projects usually live on that one device, which makes moving between phone, tablet, and desktop awkward.
Web-based optimizers like CutPlan, OptiCutter, and CutList Optimizer take the opposite path. They run in the browser, so they work on any device with a modern browser: iPhone, Android, iPad, Windows, Mac, Linux. Nothing to download, nothing to update, and if the tool supports accounts the way CutPlan does, projects sync to every device you sign into.
There is a third option most people miss, and it is the one I recommend to almost everyone: a Progressive Web App, or PWA. You add the web optimizer to your home screen and it launches full-screen with its own icon, no browser bar, no tabs. It looks and feels like a native app, but it is always the current version and works across all your devices. More on the two-tap install below.
| Factor | Native app (store) | Web app (browser) | Home-screen PWA |
|---|---|---|---|
| Install | Download + updates | None | Two taps, no store |
| Cross-device | One platform only | Every device | Every device |
| Offline use | Full | Needs connection to load | Loads from cache, sync needs data |
| Always latest version | Waits on store review | Yes | Yes |
| Project sync | Usually local only | Via account | Via account |
| Full-screen feel | Yes | No (browser chrome) | Yes |
The honest rule of thumb: if you work in a dead-signal basement shop and never switch devices, a native app earns its keep with true offline use. If you move between phone, tablet, and desktop, or you just want to start now without a download, a web app or PWA wins.

How to use CutPlan on your phone or tablet
There is no installation step, so the whole workflow is fast. Here it is start to finish.
Step 1: Open your browser and go to cutplan.ai. The app loads directly. Safari on iPhone or iPad, Chrome on Android, or any modern browser all work.
Step 2: Enter your parts. Tap the fields to add part names, lengths, widths, and quantities. On a phone the fields stack so you can fill them one-thumbed; on a tablet you get a roomier, desktop-like layout.
Step 3: Set your stock and settings. Define your sheet sizes, material thickness, and saw kerf. Kerf matters more than beginners expect: a standard table saw blade removes about 3mm to 3.2mm per cut, and on a sheet with a dozen cuts that adds up to real material. Get the kerf value right on mobile and the layout will match your saw.
Step 4: Run the optimization. Tap calculate and wait a few seconds. The optimizer runs in a web worker, so it will not freeze the page. You get a progress indicator, then cutting diagrams for each sheet.
Step 5: Review and export. Scroll the layouts, check the waste figure, and confirm part placements. When it looks right, export a PDF cut sheet to print, email to yourself, or AirDrop to another device. The export is identical to desktop. For a full walkthrough of the optimization itself, our step-by-step tutorial covers every field.
Say you are building a run of shelving and need 16 shelves at 800 x 350mm plus 3 gables at 1800 x 350mm, cut from 2440 x 1220mm sheets of 18mm ply. On your phone you enter the parts, set kerf to 3mm, and hit calculate. The parts alone total more material than two sheets hold, so you cannot do it in two, and CutPlan fits everything onto 3 sheets at roughly 29 percent waste. You were about to buy 4 "to be safe." That one 30-second check on your phone just saved a full sheet and told you exactly what to load. Screenshot the diagram or export the PDF before you leave the yard.
Add CutPlan to your home screen (PWA)
CutPlan is not a store download, but you can add it to your home screen so it launches full-screen with its own icon, no browser bar in the way.
On iPhone or iPad (Safari):
- Open cutplan.ai in Safari
- Tap the Share button (the square with an upward arrow)
- Scroll down and tap Add to Home Screen
- Name it "CutPlan" and tap Add
On Android (Chrome):
- Open cutplan.ai in Chrome
- Tap the three-dot menu in the top right
- Tap Add to Home Screen or Install App
- Confirm by tapping Add
Once added, the icon sits with your other apps and opens the optimizer in a standalone window. If you are signed in, your saved projects are right there. The experience is close to indistinguishable from a native app, with the bonus that it is always current and works across every device you own.
Tips for working accurately on a small screen
Use landscape for cutting diagrams. Sheets are wider than they are tall, so rotating the phone gives you far more of the layout without endless scrolling. Do your data entry in portrait, review the diagram in landscape.
Pinch to zoom before you cut. When a sheet is packed with small parts and the labels get tight, zoom into the exact area you are about to cut and confirm the dimension against your tape. Two-finger zoom works on both the interactive layout and the exported PDF.
A tablet is the real workshop tool. A 10-inch tablet shows about as much detail as an A4 printout, but you can zoom, swipe between sheets, and it will not disappear under sawdust. Prop it on a shelf or clip it to a magnetic mount near the saw. If you own one, this beats both phone and paper for reference.
Save before you switch devices. Sign in and save, and the same project appears everywhere you log in. No emailing files to yourself, no USB drives. Plan at the yard on your phone, refine at home on the desktop, then carry the tablet to the saw.
Common mobile mistakes to avoid
Skipping the kerf field on the small keyboard. It is easy to blow past settings on a phone and leave kerf at zero. Do that and the optimizer packs parts edge to edge with no allowance for the blade, so every real cut runs a few millimeters short across the sheet. Always confirm kerf before you trust a mobile layout.
Fat-fingering a dimension. On a phone number pad it is easy to type 300 as 3000 or drop a digit. One wrong part can throw off the whole plan and the sheet count. Glance over your parts list before hitting calculate, and sanity-check the total sheet count against what you expected.
Letting the optimizer rotate grain-sensitive parts. To save material, an optimizer will happily turn a part 90 degrees. That is fine for a hidden shelf, but on a visible cabinet door or a veneered face it runs the grain the wrong way and the piece looks wrong once it is finished. On a small screen the rotation or grain-direction toggle is easy to miss, so lock rotation off for any part where grain has to run a set way, and only allow free rotation on parts that will never be seen.
Trusting the layout without a final tape check. A tidy diagram on a bright phone screen is convincing, but the saw does not read the screen. Before the blade goes down, measure the piece you are about to cut against the number on the layout. One habit, and the small-screen mistakes above never reach your material.
