Foilwise: Stained Glass Calc

Foilwise does the materials arithmetic for stained glass makers, offline.

Pick a panel shape or list your own pieces, add the colours and their sheet price, choose copper foil or lead/zinc came, and see exactly how much glass, copper foil, solder or came you need - then turn it into a quote with labour, overhead and your markup or margin.

CALCULATE
• Panel: rectangle, circle, a custom area, or a list of pieces (count, width, height or area, colour)
• Colours: each with its share of the panel, a sheet size and a price per sheet or per area
• Waste allowance: simple (10%), medium (15%), complex (25%), or your own percentage
• Seams: type the internal seam length, or let Foilwise estimate it from the piece count and average piece size
• Copper foil: a suggested foil width for the glass thickness you enter, roll length and price
• Solder: a usual rate per length of seam (one or two sides), spool weight and price
• Lead or zinc came: U came for the perimeter, H came for the internal seams, stick length, an offcut allowance, and price per stick

RESULTS AND QUOTE
• Panel area with waste, sheets to buy per colour, and materials cost
• Foil length and rolls to buy, or solder weight and spools, or came sticks (U and H counted separately)
• Materials total, then add labour hours and rate, overhead percentage, and a markup or target margin - both shown side by side
• Quote price, profit, and price per square foot or square metre
• Copy or share a plain-text shopping list and quote

PROJECTS
• Save any calculation as a project, with notes
• Rename, duplicate or delete (with undo)
• Keep a supply price list of the glass colours you buy often, so a new project starts from them

SETTINGS
• Metric or imperial units, currency symbol, light or dark theme
• Default waste, solder rate, foil roll, and came stick settings
• Backup and restore to a file you choose, through the share sheet

WORKS OFFLINE, STAYS ON YOUR PHONE
Foilwise has no internet permission, so it cannot send your projects anywhere. Everything stays on your phone.

FOR PLANNING ONLY
Foilwise works out materials and cost. It does not replace the product labels and safety information for solder, flux, lead or zinc came - always follow those.
