Paint buddy

Paint Buddy takes the guesswork out of your next painting project. Enter your room's dimensions and it instantly tells you how many litres of paint you need, how many cans to buy, and roughly what it will cost — all completely offline.

No more standing in the hardware store doing math on your phone's calculator, and no more buying two cans when one would have done (or running out halfway through the second coat). Paint Buddy gives you a clear, realistic estimate in seconds.

WHAT IT CALCULATES
• Total paintable wall area from length, width and height
• Optional ceiling area
• Automatic subtraction for doors and windows
• Paint needed for any number of coats
• Number of cans to buy based on your can size
• Estimated cost from a price per litre

WHY YOU'LL LIKE IT
• 100% offline — no internet connection required
• No account, no sign-up, no ads tracking you around
• Live results that update as you type
• Remembers your usual coverage, can size and price
• Clean, modern design with light and dark themes
• Tiny, fast and respectful of your privacy

HOW IT WORKS
1. Enter the room length, width and wall height.
2. Add how many doors and windows to skip.
3. Set the number of coats, the paint's coverage (m²/L), your can size and price.
4. Read off the litres, cans and cost — done.

Whether you're refreshing a single bedroom, repainting the whole apartment, or just planning a weekend DIY job, Paint Buddy helps you buy the right amount of paint the first time.
