CalcNova: Scientific Calc brings everyday arithmetic and advanced scientific calculations together in a clean, easy-to-use Android app. Enter complete expressions, see live results, and keep your calculations organized—all offline.
Handle simple sums or work through expressions with nested parentheses, powers, roots, logarithms, and trigonometric functions. CalcNova follows mathematical operator precedence and displays clear messages for invalid expressions, division by zero, and unsupported mathematical domains.
Explore a complete scientific keypad:
- Addition, subtraction, multiplication, and division
- Sine, cosine, tangent, and inverse trigonometric functions
- DEG and RAD modes
- Logarithms and natural logarithms
- Squares, powers, square roots, and nth roots
- Factorials, absolute values, and reciprocals
- π, e, parentheses, and percentages
Edit calculations naturally. Type or paste an expression, move the cursor, replace selected text, and insert functions where you need them. Long expressions scroll horizontally, while live previews help you follow the result as you work. After pressing equals, your expression remains editable, and you can reuse the result in your next calculation.
Keep useful calculations close at hand. Local history saves your original expression, result, angle mode, and timestamp. Tap an entry to reuse it, delete individual calculations, or clear your history with confirmation.
Make CalcNova feel comfortable for you:
- Choose Dark, Light, or System appearance
- Enable or disable haptic feedback
- Set your preferred DEG/RAD mode
- Rotate your screen while keeping the current expression
- Use a responsive layout with accessible controls
CalcNova works without an internet connection. There are no ads, subscriptions, or account requirements. Your calculation history and preferences stay on your device, and you control when to delete them.
Calculations use standard floating-point precision, with results displayed to up to 15 significant digits.
Powerful Math. Simple Experience.
