Can I change clock to 24hr using iPhone App?

[MuttNut]

Just bought the Ionic yesterday and it is my first Fitbit. 

Had a fiasco trying to download the system upgrade- after 5 hours the Fitbit and I both gave up. 

Now I am trying to find where I can change the clock to 24hr- I only have the app on my iPhone with which to do this. Is it possible via iPhone?

Many thanks.

Go to Fitbit.com Dashboard and click on the Gear Icon at the upper right and then on Settings.  Scroll down and choose 12/24 Hour as "Clock Display Time". Scroll on down and click on "Submit" and then sync your tracker.

Here is the User Manual.

Thanks for your reply. 

Unfortubately in Settings I only have the choices of:

Exercise Tracking

Heart Rate Zones

Advanced Settings

For some reason none of these have the option of the clock. 

I appreciate your help though. 

Maybe I have a rogue Ionic!

Under "Advanced Settings" should be a long list of settings including the one for Clock Display Time. Have you looked at the User Manual I sent you a link to?

[MuttNut]

Thanks, but for some reason there is nothing in Advanced Settings re. the clock or 24hr clock. 

There are not that many options to scroll, just:

Time Zone

Set automatically

Time Zone

Units

Start week on

Country

Food Database

Sleep Sensitivity

Stride Length

Sadly, nothing about clock. 

Perhaps the OS isn’t loaded properly or is malfunctioning. 

I will try to find find out how to redo the OS update. 

Thanks again. 

I had a scroll through the manual, but am none the wiser.

I suggest you contact Customer Support.

I thought the 12/24hr clock setting was based on which was running on your phone.  I use a 24hr clock on my iPhone, so my FitBit shows as 24hr clock.  I would suggest setting your phone to a 24hr clock and see if that fixes it.
