    In my tests with the sleeping and system-off modes is that the devices automatically sleeps when it does nothing. This what the function power_manage() is for. I have seen hardly any difference in current consumption when sleeping or when in power_manage.

    It's more power efficient to go to system-off but then you'll need to save all your values in flash or use pstorage.

    If sleeping is enough for you then I would just add the button handler and increment when button is pushed.

    You can use this: devzone.nordicsemi.com/.../

    Or use App_button library there are many examples and questions about this topic that can help you.
