The spec sheet, done properly.
Every product, room and price in one sheet. The budget adds itself up, and the PDF is ready to send. Free, on your own computer.
Tinn is an early version, built by one person and still in progress. Things will change, and some will be rough. Check the numbers before you order or send a budget to a client. Found something? Tell me.

Calmer, and more of it done for you.
The spec sheet is still the heart of Tinn. Around it, this version adds the things architects asked for most.
-
A start screen that tells you where things stand
Each project card shows its budget bar and status. Inside a project, Home charts the money against the budget, the status of every product, and what each room costs.
-
Product photos that sort themselves out
Tinn picks the best photo of a product and removes the background when that helps, and leaves line drawings alone. Keep up to 12 photos, choose the main one, and open any of them full screen.
-
A calmer Properties panel
Options sit under the product they could replace. A quantity can be measured in rows, and each project works in metric or imperial. Goals and requirements are there when you want them, and off until you switch them on.
-
A printed spec sheet that reads like a document
A front page with your details, a contents page, each room as its own chapter, page numbers on every page, and all the totals together at the end.
-
Your studio's fonts, per project
Give each project a heading font and a text font, or start from one of four ready pairs. The sheet, the boards and the print all use them.
-
No Save button to forget
Tinn saves every change as you work. A small dot in the title bar tells you it is done.
-
Only the tools a project needs
Hide a tool in one project with a right-click. It stays on everywhere else, and nothing is deleted.
-
A gentle start
A three-page welcome, a few quiet tips the first time you visit each place, and Villa Solberg: a sample project with real Norwegian products, links and photos.
A start screen that tells you where things stand
Each project card shows its budget bar and status. Inside a project, Home charts the money against the budget, the status of every product, and what each room costs.

The budget is the same sheet, added up.
Change a price or a quantity and the room total, the contingency and the VAT follow. No second spreadsheet to keep in step.
When the client agrees, approve the prices. Tinn keeps what was approved and shows you what has changed since.

I built Tinn because the tools for specifying a project were built for someone else: project managers, retailers, e-commerce teams. Not for the way we actually plan a space.
