Paint & Material Estimator

What you get

Work out wall area and how many litres and tins of paint a room needs.

Highlights

• Calculates paintable wall area
• Accounts for doors and windows
• Tells you litres and tins needed
• Works offline

Format & delivery

Delivered as a HTML app. Open it in any modern browser — no install, no account, no server. It works offline, and the file is yours to keep.

Immediately after your Lightning payment settles, the download link appears at checkout. No account, no email, no waiting for a message.

How buying works

Pay from any Lightning-enabled Bitcoin wallet. The checkout creates an invoice for the fixed USD price and unlocks the file when the payment settles. An on-chain fallback is available. If you do not have Bitcoin yet, the no-card guide explains the shortest route.
