Smart Calculator

Smart Calculator shows the answer while you are still typing — no need to press equals to know where you stand.

WHY IT FEELS DIFFERENT

• Live preview — the result updates with every key you press.
• Smart percent — 200+10% gives 220, exactly like you would work it out on paper.
• Natural typing — 2(3+4) and 2π work without adding a multiply sign.
• No stacked operators — press + then ×, and the app simply swaps them.
• Clear mistakes — "Cannot divide by zero" instead of a cryptic error.

SCIENTIFIC WHEN YOU NEED IT

sin, cos, tan and their inverses, ln, log, log base n, square root, cube root, powers, factorial, absolute value, rounding, min, max, average, modulo, π, e and more. Switch between degrees and radians with one tap.

HISTORY THAT SAVES TIME

Every calculation is kept. Tap a past result to drop it into the current expression, or reopen the whole expression to edit it. The ans key always holds your previous answer.
