About
Simple Voice Calculator is a voice calculator app for iPhone, iPad, Apple Watch and Vision Pro. Say a calculation like "42.75 plus 19.99 plus 120" and the total updates as you speak, with no "equals" needed.
Each number appears as its own block, so a misheard number is fixed with one tap instead of starting over. Turn on Announce Total and the app reads the result aloud.
It keeps listening while you switch to other apps: read figures out of a bank app, PDF or spreadsheet and watch the running total in the Dynamic Island and on the Lock Screen.
Speech recognition runs on-device, the app works offline and collects no data, and it supports VoiceOver, Voice Control and Dynamic Type. Free with no ads; optional Pro adds History, Favorites, iCloud sync and CSV export.
