*An engineering calculator for study and work: powers, roots, logarithms, trigonometry and parentheses.*

## What it calculates

A scientific (engineering) calculator online: powers and roots of any degree, natural and common logarithms, the exponential function, sine, cosine, tangent and their inverses in degrees or radians, factorial, the numbers π and e, and parentheses nested as deep as you need.

It suits school, university and engineering work: Calcie follows the order of operations and shows the whole expression at once, so a mistake in the parentheses is easy to spot. In the app, the scientific mode is free.

- x², x³, xʸ, square and cube roots, 1/x, factorial
- ln, log, eˣ and 10ˣ
- sin, cos, tan and their inverses, with a degrees/radians switch
- The numbers π and e, parentheses, and a 2nd key for a second row of functions

## How to use it

1. Turn on scientific mode in the mode menu and a function panel appears above the regular keys.
2. Choose degrees or radians if you're doing trigonometry.
3. Enter an expression with parentheses. Calcie follows the order of operations.
4. Tap “=”.

## Example

√(3² + 4²) → **5**

## FAQ

**Is this mode free?**

Yes, the scientific calculator is free, just like the standard one.

**How do I switch between degrees and radians?**

Use the Deg/Rad key on the function panel. The current mode is labeled on it.

**How do I calculate a power or a root of any degree?**

Enter the base, tap xʸ and enter the exponent, for example 2 xʸ 10 = 1,024. For an nth root, tap 2nd: the key changes to ʸ√x.

**Does the “Scientific” mode work offline?**

Yes. Calcie does all its math right on your device, so the mode works on a plane, on the subway and out of town. Nothing is sent to any server, and the answer appears instantly.

**Is “Scientific” available on iPad and Mac?**

Yes. On iPad the mode has its own layout with larger fields, and on a Mac with Apple Silicon Calcie runs in its iPad version and works from the keyboard. Your Premium purchase applies on every device signed in with your Apple ID.

**How do I switch to the “Scientific” mode?**

Open the modes menu, the icon at the top left of the calculator's main screen, and choose “Scientific”. Calcie remembers your choice: next time the app opens right in that mode.
