Isofitters

Piping isometrics, sketched on your phone.

Isofitters is a sketching and take-off app for the pipe trades. Draw the run in iso, and it counts the fittings and adds up the pipe for you.

Coming soon to Google Play and the App Store

What it does

Sketch in iso

Tap and drag to lay out pipe on an iso grid. Lengths are real, so the drawing stays true to the job.

Every view from one drawing

Switch between iso, plan and the four elevations, or spin the whole route in 3D.

Fittings counted for you

Elbows, tees, reducers, valves and joints are worked out from the route and drawn with standard symbols and joint marks.

Take-offs and cut lengths

Standard fitting take-offs for steel, copper, stainless, plastic, cast iron and more, or type your own.

Materials list

Fitting counts and pipe footage by material and size, ready to pull from the shop or order.

Works offline, no account

Your drawings stay on your phone. No sign-up, no ads, no tracking. Share a drawing as a picture, a PDF or a file.

Built by a commercial pipefitter for steam, chilled water, process, compressed air, plumbing and more.
