Android Question Keep a button on top of all other apps

My mother is visually impaired. I have set up an Android tablet with a great app for playing audio books. That is all it does. The audio book app is always running on the tablet and there are five large high contrast buttons - stop/start, volume up, volume down, forward and backward.

I would like to add a button using a B4A app which stays on top of the audio book app all the time. If she presses the button it will tell her what the current time is.

Is there any way of putting a button on the tablet which is always on top of the audio book app which will tell her the time when she presses it?
