Hey everyone,

I’ve been working on a mobile app designed for professionals in the construction industry — mainly for designing PVC & aluminum windows/doors, calculating costs, and generating instant quotes.

The idea is simple:
👉 Draw the window/door
👉 Get exact measurements (mm precision)
👉 Instantly calculate cost & profit
👉 Generate a professional quote on-site

It’s built to replace manual calculations and speed up the workflow for manufacturers and installers.

But I’m curious from a design & UX perspective 👇

• What would you improve in this kind of app?
• What features would make it feel more “premium” or easier to use?
• Any UI patterns you think would fit better for technical drawing apps on mobile?

I’ll drop some screenshots in the comments.
