Bend geometry matched to your bender

Exact trigonometry uses the selected bender's centerline radius, with marks shown to the nearest 1/16" at any angle you enter. Profiles with a published maker's radius use it; the others start at the NEC minimum radius until you enter the radius of your own shoe. Check take-up and radius against your bender before bending, or switch to the familiar field multipliers (30° = 2, 45° = 1.4) so your marks match the crew's. Profiles cover Klein, Greenlee, IDEAL, Milwaukee, Southwire and Gardner Bender, and you can add your own.

Faster than a slider

Tap a value and type it on a tape keypad with fraction chips. Feet and inches, 1/8, 1/16 or 1/32, millimeters or centimeters.

Questions

How much does the app cost?

$7.99 once, in the US (local prices elsewhere). No subscription, no in-app purchases, no ads. If it is not for you, Google Play lets you request a refund within 48 hours of buying.

Is there an iPhone version?

Not yet; the app is Android only for now. The calculators on this website work on any phone in the browser.

Does it work without internet?

Yes. Everything is calculated on the phone. It works in basements, tunnels and plants with no signal.

Which benders does it support?

Hand-bender profiles from Klein, Greenlee, IDEAL, Milwaukee, Southwire and Gardner Bender for 1/2" to 1-1/4" EMT. Rigid and IMC sizes depend on the shoe, typically 1/2" to 1" on EMT shoes rated for them; use the conduit type and size your bender maker approves. Templates for Greenlee 1818 and 555 mechanical and electric benders are included, and you can edit take-up and radius or add your own.

What languages is it in?

English, Spanish, French, Portuguese and German, including every step and the PDF bend sheets.
