Pipe Offset & Cut Calculator

Calculate a pipe offset and the pipe length to cut. See the formula, substituted values,
assumptions, and rounding behind the result.

Travel and cut length are shown prominently. A value the selected display grid did not change is
labelled not rounded. A rounded label means the selected display grid changed the value. Neither
label is a field-accuracy or fitting-tolerance claim.

The simple-offset calculator has no account or time limit:

- Solve from rise and run, rise and angle, run and angle, travel and angle, or rise and travel.
- Enter imperial fractions, decimal inches, or millimetres, with a 1/8, 1/16, or 1/32-inch display
grid.
- Enter one take-out value and apply it to both fittings.
- Use this app's common angle shortcuts for 11.25, 22.5, 30, 45, and 60 degrees.
- Review substituted working, modelling assumptions, an internal two-method consistency check, and
a proportioned triangle.
- If the measurements do not describe a supported offset, the app shows no cut length and tells you
what to change.

The one-time Pro unlock includes:

- Rolling offsets with set, roll, true offset, fitting angle, roll angle, travel, and cut length.
- Reusable take-outs you enter yourself, assigned by joint, plus a gap per assigned joint.
- Saved cuts that keep the original entries, result, working, assumptions, rounding, and
calculation-engine version. Up to 100 saved cuts are kept; saving another removes the oldest.
- Saved job cards that can be sent to Android's system print screen. Available destinations depend
on the device and installed print services.

The app has no ads, subscription, or account. Calculations run locally. Measurements, fitting names,
and saved cuts are kept in app-private storage on this device. A rendered job card is handed to the
print service you choose only when you select Print job card. Buying or restoring uses Google Play;
Privacy and Support open web pages.

The app ships no manufacturer fitting tables, claims no code or standards compliance, and is not
tied to a manufacturer or fitting brand. It treats pipe as straight and rigid between fittings and
makes no allowance for bend radius, spring, thermal movement, or wall thickness. Verify measurements
and fitting data before cutting.
