■ 13 new operations calculations The app is no longer inspection-only — the calculations you run on the board and in the field are here too. - Steam table: saturation temperature, enthalpy and latent heat; superheated steam and flash steam - Flow-meter P/T correction for differential-pressure meters - Gas flow conversion: Nm³/h ↔ actual m³/h ↔ kg/h - API gravity & density, gas concentration (ppm ↔ mg/Nm³, O₂ correction, %LEL) - Heat exchanger: duty, LMTD, U value and fouling factor - Pump: NPSHa, shaft power, motor load, affinity laws - Pipe pressure drop, control valve Cv - Instrument scaling (4-20 mA ↔ % ↔ engineering units), motor load from an ammeter - Combustion (O₂ ↔ excess air, fuel gas heating value), viscosity (SSU, temperature interpolation, blending) ■ No more gauge/absolute mix-ups Pressure inputs on the operations screens have a gauge/absolute toggle, so you can enter the reading exactly as the instrument shows it. ■ "?" help on every screen What the value is, a typical figure, and where to find it — now 192 entries. The glossary is built from the same explanations and is searchable. ■ Menu grouped by purpose With 38 features, the menu is now split into Tools / Inspection & Strength / Operations & Process / Reference. ■ Also - Fixed layouts that overflowed in languages with longer translations - Fixed long result values spilling out of their row - Fixed content being clipped when Larger Text is turned on - Adjusted layouts for narrow screens such as iPhone SE

■ Enter values in the units printed on the nameplate Every input field now has a unit selector. Type kgf/cm²G, psi or bar — whatever the nameplate or your reference shows — and the app handles the conversion. Set the units you use most as the default in Settings. ■ New: vertical (self-supported) tower check Combines internal pressure, dead weight, wind and seismic (static seismic coefficient method), checks tension and compression for the operating and shutdown cases, and shows a reference required thickness. Skirt check included. ■ The calculator is now scientific, with simultaneous equations Trigonometry, logarithms and DEG/RAD switching. It also solves simultaneous equations in x, y and z. ■ Surface area now takes count and insulation thickness Estimate painting and cladding areas directly from the insulation OD. ■ Also - Expanded pipe schedule table (Sch5, small-bore Sch30/160/XXS and more) - Results pinned to the top of the screen (no scrolling after every input) - Tidied up rounding in unit conversion
