Description by Mitaanshu Agarwal Written by the developer, not by AppBrain. Click to read.
Lien bundles the everyday calcs that electricians, plumbers, HVAC techs, and carpenters reach for on the truck — in a clean, fast iOS app that works without signal.
WHAT'S INSIDE (18 calculators)
- Electrical (6): wire size, voltage drop, conduit fill, box fill, motor FLA, service load.
- Plumbing (4): friction loss, fixture units, drain size, water-heater sizing.
- HVAC (4): BTU sizing, duct size, SEER cost, composite R-value.
- Carpentry (4): cut list, beam span, rafter, stairs.
MORE THAN A CALCULATOR
- Save calculations and group them into named Projects, then export a clean PDF for the inspector or the client.
- Reference tables bundled offline: NEC ampacity, conduit fill, pipe sizing, R-values, fastener guide.
- Pick your code region (US NEC, UK BS 7671, AU/NZ AS 3000); tables and formulas calibrate to it.
- 100% on-device. No accounts, no cloud, no data sync. Built dark-mode-first for job-site readability.
FREE TIER
