VoiceCalc
Officially listedAn iOS voice AI math calculator that computes the moment you speak.
VoiceCalc
VoiceCalc is an iOS voice math assistant from independent studio SmashMelon LLC, built around "just speak to compute": say an expression and get the answer instantly, while "plain-language math problems" like price comparisons and bill splitting go to cloud AI. The free tier is genuinely usable, and the AI features are a one-time $7.99 purchase, aimed at everyday iPhone/iPad users who dislike tapping in numbers.
Core Capabilities
- Direct voice calculation: say "35 times 12" and the result appears, skipping manual entry of long numbers
- AI natural language Q&A (unlocked by the lifetime purchase): comparisons like "is 10 at $3.99 or 12 at $4.99 a better deal," bill splitting with tips, discounts, and loan payments
- Conversions and multi-step math: temperature, miles/kilometers, currency, and cross-time-zone times, with parentheses, decimals, percentages, and follow-up questions
- Offline and privacy: speech recognition and basic computation run on-device and work offline; AI sends text only, never audio
- 30 languages and history: including Chinese, English, Japanese, Korean, and more, with retrievable results
- Free browser edition: an online voice calculation demo on the official site, no signup needed
Use Cases Everyday "mental math out loud" moments for iPhone/iPad users: shopping comparisons, splitting bills, discounts and tax, unit and time-zone conversions; fits students, families, and light business users. Privacy-sensitive users who want basic computation offline are fully covered free; those needing rigorous symbolic math, or Android users, should look elsewhere.
Unique Advantages In the iOS voice calculation niche it is nearly the only product whose core selling point is "voice + LLM natural language Q&A"; competitors (Voice Calculator, Simple Voice Calculator) are mostly pure offline deterministic calculators. The $7.99 lifetime purchase with no subscription is far below comparable AI math subscriptions. But be clear-eyed: Siri's built-in voice calculation is a free substitute for basic scenarios.
Editorial Review A genuinely free tier, an affordable one-time price, and healthy reception (4.43 stars/81 ratings in the US store, low fake-review risk) make it a reasonable everyday voice calculator listing. But the site's old copy claiming "100% Free / no in-app purchases" contradicts the current $7.99 IAP, three homepage testimonials look like fabricated material, and "VoiceCalc" collides with several other products — verify current details in the App Store before buying.

FAQ
Is VoiceCalc free?
It has two layers: speech recognition, basic computation, offline use, and multilingual support are permanently free ($0); the AI natural language features (price comparison, bill splitting, etc.) require a one-time $7.99 purchase (VoiceCalc Lifetime), with no subscription and no ads.
What can VoiceCalc be used for?
It replaces typing with voice for calculation: say "35 times 12" and get the result; the AI edition also answers everyday math questions like price comparisons, bill splitting, discounts, and unit/time-zone conversions, with retrievable history.
Which platforms and languages does VoiceCalc support?
It supports iOS 16+/iPadOS/macOS (M1+)/visionOS, plus a free web version; the app supports 30 languages (including Chinese, English, Japanese, and Korean). There is no Android version yet.
What is the difference between VoiceCalc's basic and AI editions?
The basic edition is free, handles deterministic calculations and conversions, and works offline; the AI edition is a one-time $7.99 purchase that taps ChatGPT/Gemini to understand natural language questions like "is 10 at $3.99 or 12 at $4.99 a better deal" and answer them.
Does VoiceCalc need internet? Is it privacy-safe?
Basic computation and speech recognition run on-device and work offline; AI features need a connection and send only text, never audio. The privacy label says "data not collected," but the AI relies on third-party large models, and the company has no public registered address and is not registered as an EEA merchant.
Is VoiceCalc the same as Android's Voice Calculator?
No. That is Vasundhara Infotech's Android app (about 6.4 million downloads), and Product Hunt also has Joey Xie's same-named web tool. The official VoiceCalc is SmashMelon LLC's iOS app — same-name products abound, so distinguish carefully.
The site claims "100% Free, no in-app purchases" — is that credible?
Not entirely — that is outdated marketing copy. The current site pricing section and the App Store IAP both show $7.99 (VoiceCalc Lifetime); "all voice on-device" only holds for basic features, while AI features send text out to third-party large models.
How is VoiceCalc different from Simple Voice Calculator?
Simple Voice Calculator (Vito) is free, ad-free, fully offline, and supports Apple Watch but has no AI; VoiceCalc mixes local deterministic calculation with online LLM Q&A, is stronger at natural-language price comparisons and bill splitting, but its AI costs the $7.99 one-time purchase.
