ShowTime Simple Clock Display

Do you, or a loved one, ever get confused when you wake up and are not sure if it is morning or night? This app will help you with that.
ShowTime will help seniors, people with dementia or anyone really who needs a quick and easy way to work out what time of day it is.
With that in mind, it has been written to be extremely simple to use.
In essence, it is a digital clock, with very clear text showing the time. In the default operation, the background will be black at night and white during the day. So if you wake up at say 1:23, and are not sure if it is 1:23 at night, or 1:23 in the afternoon, then the background will help with this confusion. if it is black, then it is 1:23 at night. If it is white, then it is 1:23 in the afternoon.
As well as the background, there is an AM/PM indicator beside the time, again helping you work out what part of the day you are in.
If you prefer, or find it less confusing, the Settings can be changed to display the time in 24-Hour format.
There is also a description, clearing indicating if it is "Night". "Morning" etc.
The text is very large and clear, but should you need to, tap on the speaker button to have the time read out to you.
By the way, it is also possible to change the settings such that the background is black between sunset and sunrise, and white between sunrise and sunset.

NOTE: so that the app continues to display the time, without any interaction, it runs in an "always-on" mode i.e. does not automatically switch to the Lock Screen after a timeout. Because of that, it might be a good idea to keep the device plugged in.

更新履歴
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.
