### 3/5 — Missing chapters of NEC

*2026-07-26*

Why are all of the chapters of the NEC not available if the app is being paid for. Should we have access to everything in the app or is there an update coming to open those chapters?

**Developer response:** Great suggestion - more tables are on the way. Chapter 9 Tables 8 and 9, dwelling services and the 220 demand factors land in the next update, bringing it to 26. Every value comes from the same data the calculators run on, so what you look up always matches what the app gives you, and it all works with no service. Anything you're always digging for, tell us and we'll get it in. Thanks!

## Version history (last 5 releases)

### 1.8 — 2026-08-21

The biggest update yet - built from what electricians asked for.

BENDING
- Offsets and box offsets now show every standard angle side by side, with marks apart and shrink for each. Pick by the room you have, tap to use. Angles that will not fit are flagged before you bend.
- The site protractor is now one tap from the bend picker. Point your phone at a bend and read the angle.

NEC REFERENCE
- 26 lookup tables, up from 21: conductor resistance, dwelling services, range and multifamily demand, and more.
- The library now follows YOUR adopted code year. Pick 2017, 2020, 2023, or 2026 and citations, tables, and articles match the book on your truck.
- Browse by chapter, search inside any table, and pin the tables you use daily.
- Every value is generated by the same engines that power the calculators, and this release re-verified them line by line against the printed NEC.

EXAM PREP
- New exam mode: timed practice exams, a readiness score, and a study path built from your weakest topics. Set your exam date and watch the countdown.

DAILY QUIZ
- Your streak now follows your work week. Weekends and holidays never break it, and practicing on them counts as bonus days.
- Earn badges at 7, 30, and 100 days and share them with the crew.
- A morning NEC tip arrives at 6:45, before you roll.

SHARE AND SAVE
- Every calculator can now send a clean results card. Text a fill check or bend layout to the crew in two taps.
- Saving a calc to a job now takes two taps, no setup.

### 1.7 — 2026-07-19

- Shareable bend cards get a refreshed look
- Minor improvements and fixes under the hood
 Same NEC-accurate math for pipe fill, bending, and all 16 calculators. Questions or ideas? We read every review.

### 1.6 — 2026-07-14

Minor improvements and fixes throughout, and a faster start so you're sizing conduit in seconds. Stay code-legal out there!

### 1.5 — 2026-07-10

Conduit Fill is now Conduit Fill & Bending Calc - fill checks and bend marks, together in one app.

 PIPE FILL %, THE WAY IT SHOULD BE

 - Over the limit? Auto Size finds the smallest compliant conduit for you
- Quick combos for real pulls: 3-phase + N + G, feeders, MWBCs
- EMT, IMC, RMC, and PVC, 1/2" through the big stuff

NEW: CONDUIT BENDING
- 11 bend types: offsets, saddles, kicks, 90s, back-to-back and more
- Exact tape-ready marks in 1/16ths (or 1/8ths - your call)
- "How to bend this": a step-by-step guide for every mark, arrow, and flip
- Pick your bender: Greenlee, Klein, IDEAL, Milwaukee, or your stamped deduct
- Full Stick Layout: plan every bend on one stick, with a cut mark
- Site Protractor: lay your phone on the pipe, read the angle live

ALSO IN THIS UPDATE
- Faster setup: your first calculation in seconds
