TrueOffset - Pipe & Conduit

The pipe offset calculator that stays out of your way: travel, run, rolling offsets, cut lengths and mitered elbows, drawn from your numbers, with no ads jumping in front of them. NO POP-UP ADS. EVER. One small banner at the bottom, hidden while you type. No full-screen ads, no videos, nothing that clears your numbers when you hit a button. SEE THE OFFSET BEFORE YOU CUT Every result comes with a drawing: the offset with its travel and run, the rolling offset seen along the pipe and from the side, each segment of a mitered elbow, the parallel runs with their start marks, the drain slope over its run. Change a number and the drawing follows. TYPE IT LIKE YOUR TAPE READS 14 1/2", 5' 3 1/2", 3/4", 2.5m — feet, inches and fractions just work. Results come out to the nearest 1/16" (or 1/8", 1/32") with feet-and-inches next to long lengths. Prefer big keys? Turn on the app keypad in Settings: ft, in, fractions and Next, easy with gloves. PIPE TOOLS • Pipe offset — travel and run for 11¼°, 22½°, 30°, 45°, 60° or any angle, with the multipliers • Rolling offset — true offset, travel, run and how far to roll the fitting; or the fitting angle for a set run • Parallel offsets — several pipes through the same offset: where each next pipe starts so the spacing stays equal • Cut length — center-to-center minus both fitting take-outs and the weld gaps, plus the take-out of an elbow cut to any angle • Mitered elbow — segmented elbow from straight pipe: cut angle, long and short side of every segment, end pieces and take-out • Pipe slope — drop over a run at ¼", ⅛" or any slope per foot, or the slope from a measured drop, with the IPC Table 704.1 minimums for the drain size Offsets work the same for conduit: the travel is the distance between your bend marks. ALSO IN THE BOX • Feet-inch fraction calculator (tape measure math) • Right triangle & squaring with the 3-4-5 check • Construction unit converter • Bubble level and inclinometer BUILT FOR THE JOB SITE • Works offline — basement, crawl space, mechanical room with no signal • High-contrast mode for full sun, plus dark mode • Screen stays on while a calculator is open • Remembers what you typed and keeps a history of your calculations • Star the calculators you use most to pin them to the top • Share any result by text or email • English and Spanish, switch any time in Settings No account, no sign-up, nothing leaves your phone. WHY CLEAN SCREEN APPS I got tired of apps that throw full-screen ads at you in the middle of a job, so I build apps with no pop-up ads. TrueOffset is the second one, after TrueSquare Calc.
