Who Each Plan Fits
Free works well for occasional calculations and quick checks. Pro makes more sense if you rely on saved history and account-based features across repeated calculations.
Pricing FAQs
Do I need an account to use the public calculators?
No. Public calculators can be used in the browser without a subscription. Account features mainly help with saved history and plan management.
What does Pro change?
Pro mainly expands account-based features such as saved history limits. The public calculator library remains accessible without forcing a paid plan for basic use.
