Previously the early morning start time could not be set to anything before 4am. This has been changed to allow you to set it as far back as midnight, such that 12:01 am would show as Early Morning.
The top-right button currently sets the screen background  to either black or white (toggles on each press). You can now hide this button in Settings, so that it is not tapped accidentally.

You can now change to an alternative app icon. The default icon, showing time 1:23, can confuse some users who think that the icon is actually displaying the current time.
Go to settings, and at the bottom, you can select an alternative icon which does not show any time.

One user was accidentally going to the Settings screen because it was just where she held her iPad, and had then found it difficult to get back to the Clock screen. Rather than move the button, which might confuse others, the following changes were made:
1) The button can be hidden completely via a setting in the devices Settings app. e.g. go to your iPads Settings and scroll down to see the ShowTime settings.
2) Back in the app, on the Settings screen, the button for returning to the Clock screen has been made more prominent.
3) If you switch the app to the background, and then switch to foreground, it will now always show the Clock screen, even if previously it had been displaying the Settings or Helps screen.

Added a setting to allow the time description e.g. "Morning", "Night" to shown (default) or not shown.
Although this would normally be left at ON, as the description can be very helpful, you now have the option to hide the description, should you want to.

The app displays information about which part of the day you are in - early morning, morning, afternoon, evening or night. The times for these have sensible default values, but you can now change the times if something works better for you. For example, the app defaults to considering 9pm as night time, but you can now change that to 8pm or 10pm or whatever suits you best.

The time can now be displayed in 24-Hour format.
The Settings screen also has a slider allowing you to alter the brightness of the display.
