Kerfo: Cut List Optimizer

Real inch fractions, numbered cut steps, and a Pro upgrade you pay for once — no subscription. Kerfo is a cut list optimizer that turns your parts list into a plywood cutting plan in seconds: enter your parts, pick your sheets, and get a guillotine cutting diagram you can follow at the saw. Everything is calculated on your phone. Works offline. No account. No ads.

WHAT IT DOES
• Cut list optimizer for plywood, MDF, melamine and any sheet material
• 1D mode for linear stock: boards, lumber, trim, pipe, metal bars and tubing
• Imperial fractions (1/16" by default, 1/32" or 1/8" optional) and metric, with decimals in both
• Saw kerf, edge trim, grain direction lock and part rotation
• Edge banding on any of a part's four edges, with parts entered at finished size or cut size
• Mix several sheet sizes, set limited or unlimited stock, and use up your offcuts first
• Choose rip first or crosscut first, and see the total number of cuts
• Yield %, sheets used and waste area for every layout
• Shows when a layout provably uses the fewest possible sheets or bars

NUMBERED CUT STEPS, RIGHT ON SCREEN
Zoom and pan the layout, then walk through the cuts one step at a time. The on-screen cut sequence is part of the free app, not a paid extra.

YOUR PROJECTS STAY ON YOUR PHONE
• Unlimited projects, saved automatically as you type
• Included in Android's automatic backup
• Export a project file to back it up or move it to a new phone, then import it back
• Search, duplicate and reuse past projects
• No sign-up and no cloud account

BUILT FOR THE SHOP
• Sample project on first launch, so you see a result right away
• Common sheet presets: 4x8 plywood (96 x 48"), 97 x 49" MDF, 98 x 49" melamine and 5x5 Baltic birch (60 x 60"), or enter any size in inches or mm
• Fast part entry: Enter jumps to the next field, and you can type 23 5/8, 23-5/8 or 23.625
• Works as a cut list calculator for cabinets, shelves, drawers and built-ins, and as a board and lumber cut list for face frames and trim

WHAT'S FREE
Everything listed above, with no limit on calculations or projects. PDF and image export (layout diagrams and parts list) are included too, with a watermark. Copy or share the parts list as text to paste into a spreadsheet or send to a panel-cutting service.

PRO: ONE-TIME PURCHASE, NO SUBSCRIPTION
Pay once and keep it. Pro is tied to your Google Play account, so there's nothing to sign in to, and Restore Purchase brings it back on a new phone.
• Clean shop PDF: numbered cut sequence, your shop name, no watermark
• Paste your parts list straight from Excel or Google Sheets, or import a CSV file
• Material cost and edge-banding totals for quotes and ordering
The price is shown in the app and at Google Play checkout before you pay.

GOOD TO KNOW
• Layouts are guillotine (edge-to-edge) cuts, the kind you make on a table saw, track saw or panel saw
• One material and thickness per project. For 1/4" backs on 3/4" cabinet boxes, duplicate the project and switch the sheet
• Rectangular parts only. No nesting, CNC or DXF export
• Everything works offline. Buying Pro takes a one-time internet connection

Made for hobby woodworkers, DIY builders, cabinet makers and small furniture shops who want clear sheet cutting plans without ads, sign-ups or a monthly fee.
