  • Phones and tablets that work with Wear OS by Google

Wear OS by Google works with phones running Android 4.4+ (excluding Go edition) or iOS 10+*6*7. Supported features may vary between platforms and countries.

Visit on your Android phone or iPhone® to see if it’s compatible.

*1 CASIO test conditions

*2 In order to be able to use these functions your Android phone must have the CASIO MOMENT SETTER+ app installed, and there must be a connection between the phone and watch. These functions are not supported in the case of iOS.

*3 GPS altitude information is used, so the indicated altitude may not exactly match the actual above sea level elevation or altitude.

*4 Default: OFF

*5 Displaying the step count reduces the battery operating time.

*6 Limited functionality when connected to iOS device.

*7 Recommended. However, a WSD-F30 watch that is already paired with a smartphone running iOS 9.3+ can also be used.
