What it does

Offsets, all three kinds

Simple, rolling and odd-angle. On a rolling offset the rise and roll are combined first, so the multiplier is applied once, not twice.

Cut length, end by end

Pick the size, the joint and the fitting on each end. It takes off the right amount for each, and won't give a cut until both ends are set.

Take-outs from the tables

Butt weld, socket weld, threaded, copper, PVC, press fit and grooved, from the published standards and catalogues, with the source named.

Saddles, miters and more

Branch saddle templates, mitered bends, slope and grade, weld metal, thermal expansion, pipe sizes and conversions.

Type it how you'd say it

18 3/8, 4' 6 1/2", 4 ft 6 in or millimetres. If it can't be sure what you meant, it asks instead of guessing.

Shows the math

Every answer opens up to the worked numbers, so you can check it against your own scratch pad.

Questions

Does it work without internet?
Yes. Everything is worked out on the phone, so it works in a basement, a vault or a plant with no signal.
Which phones does it run on?
iPhone with iOS 17 or later.
Is it a subscription?
No. One purchase unlocks it for good on your Apple ID, and "Restore purchase" brings it back on a new phone.
Where do the numbers come from?
Pipe and fitting dimensions come from published standards and manufacturer catalogues, and the app's Sources tab names each one. Double-check critical cuts against your own layout.
