All day clock settings are accessed from the RecallCue app on your phone.
RecallCue supports 20 languages on the Day Clock!
To change a language:
From the home screen click on the menu icon in the upper left hand of the screen
Select "Day Clocks" from the menu
Click on the day Clock you want to edit
Find the Language option and select the language you want t use from the dropdown.
Click the Save button
Changing a language will also change the clock format to match.
For example, if you choose a language where a 24 hour clock is used by default your clock face will use a 24 hour format. You can easily change this by editing the "Clock Format" option which lets you select either a 24 hour or 12 hour clock format.
