Notes Calculator is a smart text calculator — a notepad that does the math as you type.
Write your calculations in plain language, one line at a time, and the answer appears inline:
- Currencies: 100 USD to EUR
- Units: 3 km + 500 m in miles
- Dates: today + 3 days, or the days between two dates
- Percentages: 20% of 250, or 80 + 15%
- Variables: give a value a name and reuse it
- Running totals: total, sum, average, prev, and line references
Everything updates live as you edit, so you can play with the numbers and watch the results follow.
Works on iPhone, iPad, Android, Mac, Windows, Linux and the web.
Notes Calculator Premium (a one-time purchase) unlocks unlimited notes and syncing across all your devices.
