1. Maybe the paid version has more going on, but based on the limited capacity of the free version I was not at all motivated to spend money on the full version.Still works ok, at the moment, however it WILL need updating for the newer os as the thumbnail icon has already become blank and the phone warns its an app for an older os nd may not work properly... please update before its broken by an os updateVery cool and relaxing to watch and mess with the settings.cannot purchase full version, app says 'no internet connection', but in fact there isVan Gogh comes alive with swirling paint whose motion you control... or influence.
2. Free version has almost no functionality.
3. As far as I could tell, it was like a little flashlight over a gif.
