The upgrade allows you to get unlimited cartoon conversions.
In the free version, the screen area you can use is unlimited and the cartoon picture produced is always 256 by 256 regardless of the initial picture. 

**** The upgrade will give you pictures of size 1024 by 1024.

When you run the app, it will first ask you for permission to take a screenshot of the screen area you select and it will show you when the picture is good enough to turn into a cartoon. The indicator will turn green. Simply wait until the green go-ahead button is displayed and then convert the picture.
You can use the screen area selector on still or moving images like a running video.
You can then copy the cartoon picture to the clipboard and paste it anywhere or share it.

The app is fully functional on your Mac and does not require WiFi access. The free version is limited to 2 watermarked-cartoons each time you run the app but if you like the quality of the images, please consider upgrading for a very cheap price, it'll go a long way towards the purchase of our 125-foot yacht.
