Window Door Design: Truewindow

Truewindow is a window and door calculator for PVC and aluminium fabricators. Pick a model, enter the measurements and get the cut list, the glass sizes and a quote PDF for your customer.

36 ready-made models plus your own design: casement and tilt and turn windows, fixed, arched and angled frames, vertical and horizontal sliding, bi-fold, balcony doors, bay windows, roller shutters and insect screens. Turn every window around in 3D before you cut.

Enter sizes in millimetres, centimetres or inches with fractions down to 1/16. Truewindow works out every profile with its cut angle and nests the pieces onto stock bars (6 m by default, editable) with the least offcut. Glass sizes, glazing beads, reinforcement and hardware lists follow from the same measurements, as far as your profile system defines them.

Work with your own profile systems: copy a system from the catalogue, set your deductions and keep your own price list in the app.

Every job turns into paperwork you can send:
• customer quote PDF with your logo, extra items and a discount
• workshop sheet with the bar plan
• glass order list
• installation sheet

Open the quote in customer mode on the phone and take the customer's signature there. Keep site photos with each job and track payments.

Every formula was checked against a second, independent implementation during development, so the numbers on the cut list are the numbers you can trust at the saw.

Calculations and PDFs are made on the device without internet; only buying or restoring Pro needs a store connection. No account and no ads. Back up all projects, templates and prices to one file and move them to a new phone. Available in 21 languages.

Free to download: all models, the 3D view, measurement entry and one project. Truewindow Pro unlocks the calculated results (cut list, glass and hardware), all PDFs, customer mode, your own profile systems and unlimited projects. Pro is available as a monthly or yearly subscription.
