Mobile Window Calculator

The mobile window calculator used by installers and fabricators on the job. Offline-capable, fast, accurate — every window pricing scenario in your pocket.

Window Pricing That Goes Where You Go

Build sites, survey visits, showroom floors — the calculator needs to work where the work happens.

1

Works Without Signal

Fully offline. Every pricing calculation — profile metreage, glass area, hardware sum, labour and margin — runs on-device. Works in rural areas, high-rise concrete cores, basements, and underground car parks where signal vanishes.

2

30-Second Survey Mode

Opened on site, quickly captures a survey: width, height, configuration type, one-tap glass spec selection. Produces a price in 30-60 seconds. Used across millions of site surveys — the fastest window-specific calculator on mobile.

3

Voice-Driven Input (Beta)

"1200 by 1800, tilt turn, A-rated" — speak measurements instead of typing. Especially useful when hands are full with a tape measure, or in cold weather when gloved hands fumble the on-screen keyboard. Available in English, Turkish, German, French, Italian, Spanish, Dutch.

4

Background Sync

Surveys captured offline sync to office when signal returns. Office team sees the job in their dashboard within seconds of the installer getting back to the van. End of the friction-filled "I need to email you the survey when I get home" workflow.

Frequently Asked Questions

How fast is the app compared to desktop software?
For a 5-window survey: phone app ~3-5 minutes, desktop software ~15-25 minutes (if you still have to re-type the survey). For 30+ windows: desktop pulls ahead because of the bigger screen for configuration, but phone still leads on capture speed. Best workflow: capture on phone, review on desktop, present on tablet.
Does battery drain fast on long site visits?
Optimised for low battery draw — about 8-12% battery per hour of active use on a modern iPhone or Android. Full-day install visits with photo capture and offline sync typically end at 40-50% battery on a charged phone. Much lighter than most field apps thanks to native (not Flutter/React Native) implementation.
Can I use the mobile calculator as part of a team?
Yes. Personal use is free for single-user operation. Multi-user mode ($5-15/user/month depending on plan) adds team sync, role permissions, central admin, and bulk price list management. Most installer businesses with 3+ field staff benefit from team mode.
What phones work best?
Any iPhone 11 or later (iOS 15+) and any Android running Android 11+ with 3GB RAM or more. Older devices work but render 3D visualisation slowly. Tablets (iPad, Android) deliver the best all-day experience — bigger screen, longer battery, dedicated pen support for sketching on screen.
