Solche Anwendungsfälle in der echten Welt zu erkennen und umzusetzen, ist genau der Part, der es spannend macht! Haste gut gemacht, bleib da dran! Solche Details wie die Handschuhtauglichkeit beglücken den User Centered Designer.

Translated from GermanSpotting and building real-world use cases like this is exactly what makes it exciting. You did a great job, keep at it. Details like glove usability make user-centered designers happy.

Wenn ich mir Ma ein Sägewerk kaufe denke ich an dich. 99€ für lifetime ist auch echt oke! Wenn man bedenkt was die Maschine sonst kostet 😂

Translated from GermanIf I ever buy a sawmill, I will think of you. EUR99 for lifetime is really okay too, considering what the machine itself costs.

Habe es einem Bekannten weitergeleitet, der auch so eine Säge hat 👍

Translated from GermanI forwarded it to someone I know who also has a saw like that.

Unplanned cuts cost boards on every log.

The math that decides how much lumber you pull off a log is not complicated, but it is unforgiving. Small mistakes compound across a day of milling.

Cuts planned by eye

Reading a log from experience still leaves boards on the table when you are optimizing for target dimensions, grade class, and kerf loss at the same time.

Valuable logs under-utilized

A hardwood log that could have yielded two more clean boards is the kind of loss that does not show up until you are tallying the stack.

Kerf loss ignored

Every cut removes material equal to the blade thickness. Ignore it across a dozen cuts and your target sizes drift.

Layouts that are almost right

An almost-optimal layout still leaves usable lumber in the slabs. The gap between good and optimal is where margin lives.

A calculator built around real sawmill math.

Enter your log, set blade thickness once, pick a target cut list and a grade class. The app returns a cut plan and an expected board count before the first pass.

Plan before the first pass

Log dimensions, target boards, blade thickness, grade class. Get the cut plan and the expected yield before you start the mill.

Cut list optimization

Board placement is optimized against kerf, grade class, and log shape. Not an idealized cylinder.

Kerf math on every cut

Configure blade thickness once. Every calculation applies it to every cut, so target sizes hold across the whole log.

What the app does.

Nine features. Each one earns its place.

Yield calculator

Returns expected board count and volume for a given log and target cut list.

Cut list optimizer

Places boards for maximum usable lumber against your target dimensions and grade class.

Kerf-aware math

Configurable blade thickness applied to every cut in every calculation.

S/A/B/C grading

Plans honor standard grade-class constraints when placing boards.

Log leveling

Handles uneven real-world logs, not perfect cylinders. Suggests the leveling adjustment so boards come off at the intended thickness.

Waste reduction

Board placement and kerf accounting work together to reduce scrap per log.

Imperial and metric

Inches, feet, millimeters, centimeters. Switch units per job.

Offline

Everything runs on device. No signal required in the woods or on the landing.

Glove-mode UI

Oversized touch targets sized for work gloves and wet hands.

Four steps from log to cut plan.

The workflow the app was built around, on a working Woodmizer LT40.

The job the app does: take a real log with its real shape, a real blade with real kerf, a real target cut list, and return a plan you can execute without second-guessing it on the mill.

1

Enter log dimensions and store the order

Log diameter, length, and order details. Every job is stored so you can come back to it.

2

Set target boards and generate the plan

Enter the boards you want to pull out. The optimizer returns a cut plan and the expected yield.

Level the log

Review the plan before the first cut

Built for a working Woodmizer LT40.

The app was written around one real mill, then used on it every day since launch.

We used to do all the math at the mill with a pocket calculator, paper and pencil, or marked straight on the log. Now it takes seconds and the maximum yield is right there on the screen.

Questions we actually get.

Straight answers.

Does it work offline?
Yes. Everything runs on device. No connection required in the woods, on the landing, or at the mill.
Imperial or metric?
Both. Inches, feet, millimeters, centimeters. Switch units per job.
Can I plan a cut list before I start milling?
Yes. That is the main workflow. Enter the log, set blade thickness, enter your target boards and grade class, get a cut plan and expected board count before the first pass.
Does it account for blade thickness (kerf)?
Yes. You configure blade thickness once, and every calculation applies it to every cut.
I have been sawing for twenty years. Why would I want this?
Experience still reads the log faster than any calculator. What the app does is handle the arithmetic around kerf, grade class, and multiple target sizes at once, so you can spend your attention on the cut itself. If you already run the optimum in your head without ever leaving a usable board in the slab, you do not need this. Most sawyers, including ones with far more experience than the author, find there is something left to tighten up.
Can I request features?
Yes. The app has a built-in feature request form. Requests go straight to the developer.
