Common questions
Is there a free voice calculator I can use online without downloading an app?
Yes. Voicecalculator.app runs a free voice calculator right in your browser: press the microphone, speak a calculation like 3.99 times 21 times 0.7, and the answer appears instantly, with no account, no install, and no time limit.
How do I use the voice calculator?
Open voicecalculator.app or the iOS app, tap the microphone, and say the calculation the way you would say it to a person. There are no operators or special syntax to learn, and the recognised text appears above the answer, so you can see what was heard. You can also type instead when you are somewhere quiet.
Is the voice calculator free, or is there a subscription?
The web voice calculator is free forever, and the iOS app is a free download with free basic voice arithmetic. Only the AI features, word problems, general questions, and multi-step reasoning, need an unlock, and that is a one-time $7.99 purchase. No subscription, no monthly fee, no ads, and no recurring charges of any kind.
Can it do percentages, tips, and price comparisons?
Percentages, tips, and discounts, yes, right in the browser: say 20 percent of 80, 15 percent tip on 80, or 20 percent off 129.99, alongside add, subtract, multiply, divide, powers, roots, sin, cos, and log. Per-unit comparisons are word problems, and those are what the AI in the iOS app is for.
