I want a full screen always-visible Android tablet app that counts down the days, hours and minutes to my next future Google Calendar Appointment.
It should let me skip the countdown to the next one.
If there is an appointment earlier than the one being counted down to, it should allow me to start counting down to the earlier one(s).
The app should run on a basic Android tablet (running Andriod v. 5.0.1 or above)
The app should work in landscape mode on a display of minimum 1024x600 resolution, scalable upwards.
When the app is on, the display should stay always on until the screen is manually locked
From the main screen, you shoud be able to skip to the next appointment
From the main screen, you should be able to go back to a previous appointment, as long as that appointment would not have started.
In the settings tab you should be able to add and delete Google Account Calendars which will be used to get appointments to count down towards
You should be able to select audio notifications to warn of appointments in the future.
You should be able to turn on or off audio notifications
You should be able to specify if you want to see zero-value days and hours in the countdown timer.
