+# JSON Clock ![](app.png)
+
+  *JSON view of the time.*
+
+Written by: [David Volvoskiy](https://github.com/voloved) and fully
+inspired by  [This FitBit face](https://github.com/Sharkgrammer/clockface.json)
+
+* Displays a JSON that shows the date, time, step count, sunrise/set and battery.
+* If the Bangle's theme is dark, then it'll show in dark view (`Settings>System>Theme>Dark BW`)
+* It'll show 12 hrs if it's set so in `Settings>System>Locale>Time Format`
+* Along with the physical button, you can leave the clock by pressing the `X` next to the `clockface.json` in the tab.
+* If the steps cannot be gotten, they won't display
+* If the location isn't set, then the JSON array will ignore the sun info and instead display the time as a struct.
