## Version history (last 5 releases)

### 10.2.7 — 2026-08-15

NEW — a different fitting on each end of a spool

Spool Cut now takes a 90 on one end and a 45 on the other. One pass, one cut length. Each end's take-out is listed separately, with the source of the number beside it. Thanks to the fitter who wrote in and asked for this.

FIXED — accuracy

• Switching between Imperial and Metric now converts what you entered. Before, your numbers were re-read under the new unit, so a measurement could change meaning when you flipped the toggle.
• Deg ↔ mm/m reported the wrong slope in Metric.
• The Rolling Offset diagram labelled the hypotenuse "Travel". That side is the True Offset — Travel lies in another plane.
• Short Radius is offered only on sizes ASME B16.28 actually covers (NPS 1"–24"). Sizes outside the standard no longer show an SR take-out.
• Take-out now always states where the number came from: a tabulated ASME value, or a calculated approximation for angles the standard does not tabulate.

If you saved work in Metric before this update, it is worth checking it again.

IMPROVED

• Angle marks on the Miter Cut, Segment Elbow and Weld Prep drawings now show what they are measured from.
• Bolt numbers on the flange pattern are readable on every pressure class.
• The Saved list shows every calculator type, not just the offsets.
• The About screen reports the real app version.

### 10.2.6 — 2026-03-31

Version 10.2.6: UX Updates & New Calculator
New Features:
Right Triangle Calculator: Need to solve a quick trig problem on the site? The new Right Triangle tool allows you to input any two known values to instantly get all sides, angles, area, and perimeter with a beautifully drawn interactive diagram.

Major Improvements: Glove-Friendly Custom Numpad: We heard your feedback! Typing with system keyboards while on the job isn't ideal. We've rolled out our custom, unified Decimal Numpad to all screens (Spool Cut, Weld Calc, Miter Cut, Area/Volume, etc.). Enjoy faster, error-free inputs without the UI jumping around.
Refined Metric/Imperial Support: Seamlessly switch between Metric (m/mm) and Imperial (ft/in/fraction) without losing your math precision.

 Bug Fixes & Data Integrity:
ASME Database: Verified and corrected minor discrepancies in the internal ASME B16.9 database for 1/2" and 3/4" pipe sizes.
Share Sheet Fixes: Fixed a crash exclusively affecting iPad users when trying to share their calculation results. Sharing your takeouts and spool cuts is now smoother than ever.
UI polishes to ensure text and diagrams don't clip on smaller devices.
