Ohhhhh.... I see what the deal is. It's free download, but there is a monthly subscription fee to use it. PrimeTime2Go
Second paragraph says Download PrimeTime2Go free and if you like it you can subscribe to the service for $7.99 per month. Not exactly free. I thought it sounded too good to be true.
Some of the apps on AppWorld say free when in reality they are not free to use.
