LogMaster: know exactly what to cut — before you make the first cut.
Scan the log with your iPhone or iPad. LogMaster shows you the cuts a master sawyer would make — a step-by-step sequence sized to your mill, your products, and your prices. New to sawmilling? You'll saw your first log like your ten-thousandth.
From scan to cut plan, start to finish.
A real log, scanned and solved in the app — no narration.
Every miscut is money left on the ground.
Deciding how to cut a log by eye — or even with a tape measure — means you're guessing. LogMaster replaces the guess with a calculated cut plan based on the actual geometry of that specific log.
"The difference between a good cut and a great cut is knowing what's inside the log before you touch it with the blade. LogMaster gives you that knowledge in seconds."
From log to cut plan in four steps.
No complicated setup. No steep learning curve. Open the app, scan the log, and get a cut plan in under a minute.
Scan the log
The LiDAR scanner captures an accurate 3D model of the log — diameter, taper, and shape. Same scanning engine as LogScanner, included at no extra cost. No separate app needed.
Review the geometry
LogMaster displays the log's actual measurements on screen. Diameter, taper, volume — no tape, no estimation. What you see is exactly what you've got.
Get your cut plan
The optimization engine calculates the cut pattern that maximizes board foot yield from that specific log's shape and dimensions. Every log is different — your cut plan should be too.
Export and cut
Save and export the cut plan as a report. Take it to the mill, share it with your crew, or archive it for your records. Every decision documented.
Shooters have a rule: spend as much on your optics as on your rifle — the finest barrel can't hit what it can't see. Your mill is the rifle. LogMaster is the glass. It sees the log — sweep, taper, every usable inch — and tells you exactly where to aim each cut.
Everything in LogScanner, plus optimization.
LogMaster is the complete package — full scanning is included, so you don't need to open a separate app just to capture the log.
LiDAR scanning
Full LiDAR scanning included. No separate app needed. Works on iPhone 12 Pro and later, and on iPad Pro with LiDAR.
Cut optimization
Calculates the cut pattern that gets the most board feet out of each log's actual shape. Stop leaving value in the slab pile.
Yield maximization
Every log is different. LogMaster treats it that way — each cut plan is calculated from that log's specific geometry, not a generic template.
Export cut plans
Save and share reports for each log. Build a record of every cut decision you make. Share with your crew or archive for future reference.
When the machine out-plans the expert.
One expert at a time, computers took the lead.
| Year | Field | What happened |
|---|---|---|
| 1994 | Checkers | Chinook wins the Man-Machine World Championship |
| 1997 | Chess | IBM's Deep Blue defeats world champion Garry Kasparov |
| 2011 | Jeopardy! | IBM Watson beats the show's two greatest champions |
| 2016 | Go | AlphaGo beats Lee Sedol, 4 games to 1 |
| 2017 | Poker | Libratus beats four top pros at no-limit hold'em |
| 2020 | Biology | AlphaFold predicts protein shapes as well as lab experiments |
| 2026 | Sawmilling | LogMaster plans the log: 47 million board placements checked before the first cut |
In each case the computer checked more options than any person could and found better answers. The sawyer still runs the mill; LogMaster does the planning no person has time to do by hand.
What makes it smart
Intelligence is the ability to adapt. Merriam-Webster's first sense: “the ability to learn or understand things or to deal with new or difficult situations.”
- No two logs are alike. LogMaster scans the real shape of this log, not an average one.
- No two mills are alike. The cut plan is built for the sawmill you set up.
- No two orders are alike. It optimizes for the boards and prices you choose.
A rule of thumb gives every log the same answer. LogMaster finds this log's answer.
Good advice: measure twice, cut once. Great advice: scan once.
What one scan of one log sets in motion:
| Count | What it is |
|---|---|
| 275,000 | LiDAR points captured |
| 54,000 | spots measured on the log |
| 173 | distinct rotations checked |
| 31,089 | cutting plans built |
| 124,356 | board stacks calculated |
| 1.17 million | individual board evaluations |
| 47 million | board placement checks |
| 21 steps | in the cut sequence produced |
| 70% | green recovery |
The scan happens on an iPhone or iPad you already own. Counts are from one LogMaster scan and optimization of a single log; results vary by log and mill. LogMaster gives estimates; it is not a certified scaling instrument.
