Window Design App
The window design app built for professionals who work from their phones. Design casement, tilt-turn, sliding, and bespoke windows with millimetric accuracy — no CAD training required.
Design Windows in Your Pocket
What a phone-native window design app brings that desktop CAD can't.
Finger-First Interface
Pinch to zoom, drag to dimension, tap to add a mullion. Designed for touch from the ground up — not ported from a desktop mouse-driven program. Junior staff pick up the workflow in 30-60 minutes; senior staff who've used CAD for decades also adapt quickly.
On-Site Design Capture
Meet the client, measure the existing opening, draw the new window on the spot, and print or email the design before leaving. Turns a 2-visit quote process (measure → design → present) into a 1-visit process — a huge competitive advantage in window sales.
Real-Time Visualisation
As you draw, the window renders in 3D with accurate proportions, colours, and textures. Preview the window on an uploaded photo of the building to show clients exactly how it'll look — the single most effective sales tool in window replacement work.
Export to Anywhere
PDF drawings, DXF technical files (for CAD import), CSV schedules (for production planning), IFC (for BIM workflows). Whatever format the next person in the chain needs, Doorwin produces it — the design doesn't get stuck in a proprietary format.
