After using the free app for a few weeks, I found I got to sleep more quickly and slept more soundly. I purchased the paid app particularly to have the Wee Hours Rescue feature which is wonderful for those times of waking at 4:30 am with the mind racing. I rarely hear a full sleep meditation as I have fallen into a deep sleep well before the end.
