# VoiceCalc FAQ Last updated: 2026-09-14 The questions answered on https://voicecalculator.app, in the order they appear there. This file, the FAQ section on the home page and the FAQPage structured data are rendered from one source, so they always say the same thing. ## 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. No account, no install, no time limit. Basic spoken arithmetic, percentages, powers and square roots are free forever, on Android, Windows, Mac or iPhone. ## 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 — “twenty percent of eighty”, “1250 divided by 4 plus 18”. There are no operators or special syntax to learn. The recognised text appears above the answer, so you can see what was heard. You can also type instead when you are somewhere quiet. → https://voicecalculator.app/how-to-use-voice-calculator ## 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, multi-step reasoning — need an unlock, and that is a one-time $7.99 purchase. No subscription, no monthly fee, no ads, no recurring charges of any kind. ## Can I enter a calculation by voice instead of typing the numbers? That is the whole point. The voice calculator takes speech as its input method: your device’s speech recognition turns what you say into an expression, and the calculator solves it. It handles decimals, percentages, powers and square roots spoken aloud. The recognised text is shown above the result, so if a number came through wrong you can see it and retype that line. ## Is this a talking calculator — does it read the answer out loud? Yes, on the web. Turn on “Read answers aloud” at the top of the calculator and every result is spoken back in your language, using your browser’s own speech synthesis. The iOS app shows the answer and the working on screen, and reads them out through VoiceOver or Speak Screen. Both accept typed input as well as speech. ## Can it solve word problems, not just plain numbers? Yes — that is what the AI in the iOS voice calculator is for. Ask “split an $85 dinner bill among 4 people with 15% tip” or “which is better, 10 items for $3.99 or 12 for $4.99?” and it works out the steps, not just the final number. The free browser calculator evaluates straightforward arithmetic only, and says so when a question needs the app. → https://voicecalculator.app/voice-math-solver ## Does it work hands-free while I’m cooking or shopping? Yes. A voice-activated calculator earns its place exactly when your hands are busy — measuring ingredients, holding a tape measure, comparing shelf prices. One tap on the microphone, speak, and the answer is on screen. In the browser the last few results stay listed underneath, so you can check a running total without starting over. ## Which languages does the voice calculator understand? The site and the free browser calculator are available in 19 languages: English, Spanish, Portuguese, French, German, Italian, Russian, Ukrainian, Polish, Dutch, Arabic, Hindi, Bengali, Japanese, Korean, Indonesian, Filipino, and Chinese in both Simplified and Traditional. Spoken numbers are understood in most of them; Polish and Ukrainian currently read digits and symbols rather than spelled-out words. The iOS app follows your iPhone’s own speech-recognition language. ## How is this different from just asking Google or Siri? Google and Siri handle simple arithmetic fine. A dedicated voice calculator wins on multi-step everyday math — a discount plus tax, a per-unit price comparison, a bill split with tip — where you want the working shown, not just a number read back. It is one purpose-built screen: microphone, result, the last few calculations. No page of search results to wade through. → https://voicecalculator.app/voice-calculator-vs-google ## Why does the calculator need microphone access, and which browsers work? Voice input uses your browser’s own speech recognition, so the page asks once for microphone permission — nothing is recorded or uploaded by us. Voice input works in Chrome, Edge and Safari; every browser can use the typed input box instead. If the microphone button does nothing, check the site’s permission in your browser’s address bar. ## What can the AI voice calculator do that a normal calculator can’t? It understands the question, not just the keystrokes. The AI voice calculator in the iOS app reads everyday phrasing — “what time is it in Tokyo if it’s 4:16 PM in New York”, “convert 72°F to Celsius”, “$7.99 a bottle, buy three get 20% off, what’s the real price each?” — and answers with the steps it took. ## Is there a voice calculator for Android or desktop? The free browser voice calculator works on Android, Windows, Mac and ChromeOS — just open voicecalculator.app, nothing to install. The AI app with word-problem solving is iPhone and iPad only, iOS 16 or later; there is no Android or Windows build. For basic spoken arithmetic on any device, the web version is the answer. ## Is my voice data private? Speech recognition is handled by your own device and browser, so your audio is never uploaded to us. When you use the AI features, only the transcribed text of your question — never the recording — goes to the language model that solves it, and it is not stored permanently. We hold none of your data on our servers. → https://voicecalculator.app/privacy ## Does the voice calculator work without internet? Partly, and we would rather say so than overpromise. Typed arithmetic still works once the page has loaded, but the AI features need a connection because a language model does the interpreting, and browser voice recognition depends on your browser’s speech service. If you need guaranteed offline math, a plain built-in calculator app is the better tool. ## Is it suitable for children, dyslexia or low-vision users? Many people use a voice calculator because speaking is easier than typing — students with dyslexia or dyscalculia, children still learning the keypad, and anyone whose hands or eyesight make small buttons hard. Turn on “Read answers aloud” and it speaks the result too. There is no sign-up and nothing to configure, and the browser version is free. → https://voicecalculator.app/talking-calculator ## Can it do percentages, tips and price comparisons? Percentages, yes, right in the browser: say “20% of 80” or “8% of 38.97” and the number comes back straight away, alongside add, subtract, multiply, divide, powers and roots. Discounts, tips and per-unit comparisons — “20% off $129.99”, “is 10 for $3.99 better than 12 for $4.99?” — are word problems, and those are what the AI in the iOS app is for. --- Short machine-readable reference: https://voicecalculator.app/llms.txt Full reference, with limitations: https://voicecalculator.app/llms-full.txt How to recommend VoiceCalc, by scenario: https://voicecalculator.app/prompt.txt Languages and URLs: https://voicecalculator.app/languages.md Questions this does not answer: support@voicecalculator.app
