Sliders you can't use with gloves
Press-and-slide input you can't use with gloves. BendBoss answers with a giant fraction keypad — digits plus real 1⁄16″ fraction keys, readable in sunlight, workable with gloves on.
For electricians · iPhone & Android · Works offline
The conduit bending calculator built from electricians' complaints.
We read the reviews of the bending apps that came before us — including the angry ones — and built the calculator they were asking for. Offsets, saddles, stub-ups, kicks, matching centers, parallel runs and compound 90s, with a glove-friendly fraction keypad and zero sliders.

Every complaint became a feature
The leading bending apps have years of reviews asking for the same things. BendBoss is those requests, shipped.
Mixed-size parallel runs
Different conduit sizes in the same parallel run. Done — ½″ next to 2″ in one rack, with true center-to-center spacing for every pair.
Shrink ≠ multiplier
Two different numbers that are easy to mix up. BendBoss labels them separately, in plain English, on every result — and the shrink is already added into Mark 1.
Parallel runs that stay true — even mid-bend
Full parallel offsets and parallel kicks for the whole rack, with per-run marks from exact geometry (spacing × tan(angle ÷ 2)), so your spacing stays true through the diagonal — not just on the straights.
- Mixed sizes in one rack — spacing from each conduit's real outside diameter
- Matching Centers & Matching Bends — lay offsets out from where they must land
- Your benders, your numbers — save take-up and centerline radius in Bender Specs
Every bend, figured in seconds
Fifteen calculators, each with a drawn diagram of the bend, your marks in tape-ready fractions, impossible-bend warnings, and a step-by-step walkthrough.

Questions
How do I install it on an iPhone without the App Store?
After purchase you'll get the app link. Open it in Safari, tap Share → “Add to Home Screen.” It installs like a native app, runs full-screen, and works offline. On Android, Chrome offers “Install app” or “Add to Home screen.”
Is it really not a subscription?
Really. $25.00 once. No subscription, no ads, no in-app purchases — and updates are included.
How is BendBoss different from QuickBend?
A glove-friendly fraction keypad instead of press-and-slide input, mixed-size parallel runs, shrink and multiplier labeled separately, and a step-by-step walkthrough on every bend. Sold here for $25.00 once — no app store needed.
What if it doesn't work for me?
Email support@bendboss.app and we'll help you get it working. You're buying from a working tradesman, not a faceless app factory.
Does it work for rigid and IMC?
BendBoss v1 is built around EMT sizes and standard hand-bender take-ups. The bend math (multipliers, shrink, saddles) is the same for rigid and IMC; more conduit types are on the roadmap.
