• Sign by hand and export a professional PDF or Excel sheet

Plus dozens of fixes and UI polish across the app. 2026.08.04 Aug 30 Electrical Calculations — a complete new section, 69 calculators.

LOAD CALCULATION
Size a whole structure's electrical load in one place: connected load, maximum demand, design current, phase balance and the sanctioned load figure your utility asks for. Export the sheet as Excel or PDF with your company details on it.

CABLES & CONDUIT
Cable sizing, voltage drop, maximum run length, cable weight and drum counts, conduit fill, cable tray sizing and support quantities.

PROTECTION & MOTORS
Breaker and MCB sizing, RCD/RCCB selection, fault level, motor full-load current, starter and contactor selection, power factor correction.

LIGHTING

POWER SOURCES
Transformer sizing and loading, DG set sizing and fuel cost, UPS and battery banks, solar PV capacity, panel counts and off-grid storage.

QUANTITY & BOQ
Wiring point, wire, conduit, termination and distribution board estimators that feed straight into your BOQ.

NEW CONVERTERS
Electrical units, conductor size (mm² / AWG / kcmil / SWG) and illuminance (lux / foot-candle).

Everything follows your region — India, USA, Canada, Australia, Europe and the Gulf each get their own voltages, demand factors and standard breaker ratings.

ALSO IN THIS UPDATE
• Calculator inputs now sit two per row, so there's less scrolling to reach your answer
• Region-accurate concrete grade data
• Area results show in m² and sq ft at once
• Fixes: web PDF export, Pro access on the web, and grid layout on wide screens

Electrical sizing results are indicative and should be verified by a licensed electrical engineer against your local code. 2026.08.03 Aug 24 NEW — Formwork Sheet (Pro)
Plan a whole project's shuttering in one place. Build an element
schedule and the app derives your ply sheets, battens, walers, ties,
props, back-props and a complete scaffold list from it — then tells
you the PEAK quantity you actually need to buy, not the cumulative
area you bill. Includes cycle planning, de-shuttering sets and eight
validation checks that flag a take-off before you issue it.
Export a branded PDF, push quantities to a BOQ, or send a row
straight in from any shuttering calculator.

NEW — Brick Size Library
Your own brick and block sizes, saved once and used everywhere.
Region-aware seed catalogue, a default per brick/block type, and
auto-fill across all 24 brickwork calculators. Backed up and synced

ALSO IN THIS UPDATE
• Calculator inputs now sit two per row, so there's less scrolling to reach your answer
• Region-accurate concrete grade data
• Area results show in m² and sq ft at once
• Fixes: web PDF export, Pro access on the web, and grid layout on wide screens

Electrical sizing results are indicative and should be verified by a licensed electrical engineer against your local code. 2026.08.03 Aug 24 NEW — Formwork Sheet (Pro)
Plan a whole project's shuttering in one place. Build an element
schedule and the app derives your ply sheets, battens, walers, ties,
props, back-props and a complete scaffold list from it — then tells
you the PEAK quantity you actually need to buy, not the cumulative
area you bill. Includes cycle planning, de-shuttering sets and eight
validation checks that flag a take-off before you issue it.
Export a branded PDF, push quantities to a BOQ, or send a row
straight in from any shuttering calculator.

NEW — Brick Size Library
Your own brick and block sizes, saved once and used everywhere.
Region-aware seed catalogue, a default per brick/block type, and
auto-fill across all 24 brickwork calculators. Backed up and synced
with the rest of your data. Open it from Settings or the Brick Work
page.

NEW — False ceiling calculators
Gypsum Ceiling, POP Ceiling and Grid Ceiling, with section and plan
drawings, regional advisories, and material rates stocked for all
six regions.

IMPROVED — Shuttering, redrawn
17 element calculators, each with a new two-view drawing that shows
WHICH FACES GET FORMWORK - a footing is sides only, a beam is soffit
plus two sides. Tap any field and its dimension lights up on the
drawing.

IMPROVED — Quantity tab
Calculators are now ordered by how relevant they are to your role
and region. Nothing is hidden; your favourites still come first. 2026.08.02 Aug 18 This is our biggest update yet.
