## What is Bendbook?

One payment. No subscription. No ads.

Bendbook sets conduit bending to the hand bender you actually use. Pick your bender and your conduit size, type in the job, and get every mark on a numbered drawing, with the steps in bending order. It works offline and needs no account.

BENDING, SET TO YOUR BENDER
• Made for Greenlee® (840–844 and the 1800), Klein®, Ideal® and Gardner Bender® benders. For any other bender, measure one stub and Bendbook works out the take-up and radius.
• Every mark is numbered, and each step says which head mark to use, the angle, and when to roll the stick 180°.
• Every answer shows its source: the maker's own worked example, or "as printed" with the multiplier.
• Two modes: Exact geometry, or the rounded numbers printed on your bender, so the marks match the head in your hand.

18 BEND TYPES
Offset, rolling offset, matching-bends offset, matching-centers offset, parallel offset, 3-point saddle, 4-point saddle, 90° stub-up, back-to-back 90s, concentric 90s, kick, kick with 90°, matching-bend kick, matching-center kick, parallel kick, parallel kick forward, segmented 90° and compound 90°.

RACKS AND LAYOUT
• Racks of 2 to 8 conduits, with a mark table for each conduit.
• A multi-bend layout on one stick: add the bends in order, see the 360° total between pull points, and get every mark measured from end A or end B. Warnings tell you when the bends are too close for the shoe or the stick is too short.
• Save racks and layouts to your phone as jobs.

FIVE CODE CALCULATORS
Conduit fill, box fill, voltage drop, wire size and ampacity, and Ohm's law. Values come from the NEC® 2023 tables, with a switch for the 2026 edition. Under every answer you see the table and edition used and the values behind the result.

FREE AND PRO
Free on every bender: offset, rolling offset, matching offsets, 90° stub-up and Ohm's law, so you can check Bendbook against your own bender before you pay. Pro unlocks everything else with one payment. It is not a subscription, it supports Family Sharing, and you can restore it on a new phone.

PRIVATE
No account and no sign-in. Your benders, inputs and saved jobs stay on your phone. The app sends only anonymous usage statistics and crash reports, and the purchase goes through Apple.

ENGLISH AND SPANISH
Bendbook follows your phone's language.

A TOOL, NOT THE CODE
Bendbook is an aid. You remain responsible for following your bender maker's instructions, the code adopted where you work and your inspector's decision.
