Apple Watch voice calculator

When your phone is in your bag or across the room, the calculator on your wrist is quicker. Simple Voice Calculator comes with a full Apple Watch app: say the numbers, watch the total update, and remove a misheard number without reaching for your phone.

Why a calculator on your wrist

The watch is the device you can use with a full shopping basket or a dumbbell in one hand. Raise your wrist, tap, and say the numbers. Plenty of calculator apps don't have a watchOS version at all. Simple Voice Calculator's Watch app is included free with the iPhone app.

What the Watch app does

Runs on the watch itself

It isn't a remote control for your iPhone. The calculator runs on the watch, with an interface laid out for the small screen.

Answers as you go

Results update in real time as you build the equation. There's no equals button. The answer is on your wrist as soon as you finish speaking.

Watch face complication

Add Simple Voice Calculator to your watch face and it's one tap away whenever you need it.

Fix a misheard number

Every number shows as its own block. Tap a misheard one to delete it and say it again, without starting over.

Free, no Pro needed

The Watch app comes free with the iPhone app and needs no subscription. History, Favorites and iCloud sync are Pro features of the iPhone and iPad app.

Setting it up

  1. Install the iPhone app first. Download Simple Voice Calculator from the App Store on your iPhone. The Apple Watch app installs with it.
  2. Make sure it's on the watch. In the Watch app on your iPhone, go to My Watch, scroll to Voice Calculator and make sure "Show App on Apple Watch" is on.
  3. Add it to a watch face (optional). Touch and hold the watch face, tap Edit, and add the Voice Calculator complication to any slot.
  4. Calculate from your wrist. Open the app, tap the microphone, and say the calculation.

Compared with other voice calculators

Most voice calculator apps on the App Store have no Apple Watch app. VoiceCalc, for example, runs on iPhone, iPad and Mac, but not on the watch. Simple Voice Calculator is one of the few with a native Apple Watch app, a watch face complication, and free core features.

The full breakdown is in the voice calculator comparison.
