I got tired of ugly, cluttered calculators that break when you work with real money — salaries, investments, and net worth in millions and billions.
So as a solo developer I built calcwith.com — a clean, fast and modern finance calculator.
**Key highlights:**
• Smart number formatting: 1,250,000 → 1.25M, 2.4B, 980K etc.
• Beautiful minimal interface
• Works perfectly on mobile.
I built a lightweight whiteboard tool that’s perfect for quickly explaining ideas, sketching schemes, or making simple calculations.
With just a click, you can:
🖊 Draw
✍ Write notes and ideas
🧮 Make quick calculations right on the board
It’s fast, intuitive, and perfect for anyone who wants to brainstorm or explain concepts without switching between multiple apps.
Give it a try and see how simple planning and calculation can be!
