Pipe Offset

The offset solver that gives you the cut, not just the travel — labeled iso diagram, provably-correct math, works offline. One-time $19.99, no subscription, no account.

Solve the offset. Read the cut off the drawing. Own it once.

Pipe Offset turns rise, roll, and your fitting angle into the one number you actually cut to — the end-of-pipe cut length — and draws it on a labeled isometric that redraws live as you type. There's no calculate button, no login, and no subscription. It works in airplane mode on the jobsite, forever.

BUILT FOR THE CUT, NOT JUST THE TRAVEL Most offset apps stop at center-to-center travel. Pipe Offset keeps going: it subtracts each fitting's takeout and folds in thread makeup or Victaulic groove engagement, so the number on screen is where you actually cut the stick. • Simple and rolling offsets — enter rise, roll, and a continuous fitting-angle field (45 / 30 / 22.5 / 11.25 / 60 are one-tap seeds, never the only path) • Welded, threaded NPT, and Victaulic-grooved fitting systems — with user-overridable takeout / makeup, so an un-tabled combo is never a dead end • Every pipe size and schedule — no 42-inch cap • Fractions in the fitter's own notation, inches and mm

ACCURACY YOU CAN VERIFY BEFORE YOU PAY The cheap apps are provably wrong — an 8-inch rolling-offset error is real out there. The complete single-offset instrument — correct trig, takeout-to-cut, and the labeled iso — is FREE, so you can cut a real stick and check our math before spending a cent.

WHAT'S FREE, WHAT'S NOT Free, forever: the full single-offset solve (simple + rolling), the continuous angle field, all pipe sizes and fitting systems, the per-solve takeout override, the live labeled isometric, and the end-of-pipe cut. One-time unlock ($19.99): parallel / equal-spread banks (N pipes, spacing, staggered cuts), obstruction mode (type a clearance, get the minimum offset that clears it), save & recall named jobs, and export — labeled iso PNG, cut-sheet PDF, and a re-importable JSON round-trip. That's it. No subscription. No account. Restore Purchases is built in for a new phone or a reinstall.

Priced like the $54 wheel on your truck — bought once, not rented by the year.

Always confirm against your own layout and cut list. Pipe Offset supports your layout decisions; it is not a substitute for code, spec, or a qualified fitter's judgment.
