Frequently Asked Questions

How do I switch between DEG and RAD mode?

Tap the DEG/RAD indicator in the top-left corner of the display, or use the DEG button on the keypad to toggle angle units.

How do I graph multiple equations at once?

Open the Graphing tab, tap "+ Add equation," and enter your function. Each equation gets its own color so you can tell them apart on the graph.

How do I see the exact coordinates on a graph?

Tap directly on a curve, or on any marked point (circle or diamond), to reveal its coordinates.

How do I zoom or pan the graph?

Pinch to zoom in or out, and drag with one finger to pan around the graph. Tap "Reset" to return to the default view.

How do I convert between number bases (hex, decimal, octal, binary)?

Open the Base-N tab, select your input base (HEX, DEC, OCT, or BIN), and enter a value. All four representations update automatically.

How do I use the logic gate functions (AND, OR, XOR, etc.)?

Enter your first value, tap the logic gate button (AND, OR, XOR, NAND, NOR, XNOR, or NOT), then enter the second value and press equals.

How do I change the bit width in Base-N mode?

Tap 8-bit, 16-bit, 32-bit, or 64-bit above the keypad to change how results are calculated and displayed.

How do I use the matrix functions?

Tap MTRX to open the matrix input panel, select a matrix slot (A-F), and enter your 2x2 values. You can then reference matrices in calculations.

How do I access constants like pi, e, or planetary gravity?

Constants are available in the sidebar menu (tap the menu icon), or directly on the keypad for pi and e.

Is my calculation history saved?

Yes, your calculation history is saved locally on your device and accessible from the sidebar.

I found a bug. How do I report it?
