This was one of my favourite apps but it is impossible to save now as an advert pops up full screen and there is no X to close the advert. Any touch of the screen redirects you to google play to encourage you to install the app being advertised. Clicking back just takes you to the advert again and there is no way of saving the picture you created. It's an endless loop of advert, google play, advert, google play. So I have had to install as the app is now unusable.
