Speak Calculator & History

Speak Calculator & History brings together everyday arithmetic, scientific functions, unit conversions, age calculation and adult BMI estimates. The app interface is in English.

CALCULATORS AND TOOLS
- Use the standard calculator keypad.

- Estimate adult BMI from weight and height.

OPTIONAL SPEECH INPUT
Speech input uses an Android speech-recognition service installed on your device, such as Google's service when available. Availability and recognition accuracy depend on the device, supported language, provider, network connection and surrounding noise. Speech recognition and offline voice input are not guaranteed. You can use the keypad instead.

LOCAL HISTORY AND ADS
No Techtenstein account is required. Calculation history is stored on your device. The app includes advertising; information about advertising providers and consent is available in the privacy policy.

This app is a general-purpose calculation tool, not professional advice. Adult BMI is a screening estimate for people aged 20 and over, not a diagnosis. Check important results before relying on them.
