With that app you can assign free texts (maybe email addresses or often needed strings) to 5 buttons.

Pressing of one of these buttons will copy the assigned text to the Clipboard.

Additionally two further special buttons exists to copy ...

- the current GPS position
- the current date (and time)

to the Clipboard.

One of these buttons can defined as your favorite button. Every time the app comes to foreground, the text of that favorite button is copied to Clipboard (without pressing the button needed).
