Smart Notepad & Calculator

฿99.00

Notepad Calculator is a smart calculator disguised as a notepad. Instead of juggling a calculator app and a notes app, just write what you're thinking — every line is calculated instantly, right next to your words. Write math the way you think Type expressions in plain language and get answers on the same line: 500 + 200 * 3 → solved as you type, no equals button needed 10 km in miles, 5 feet 6 inches + 8 in today + 3 weeks, Jan 1 2025 to Mar 1 2025 tax = 15% then reuse price + tax anywhere below 8%, VAT, tip, subtotals and totals with #tag aggregation Every answer becomes a variable you can reference later, so multi-step calculations stay readable.
