Why is this app not removed?

The doesnt even display a calendar or show the phases. On the info section it says "many thanks to so and so"! My comment is why is Apple allowing these people to rip us off? A cheap app is still an app paid for and not provided as represented! Many thanks for ripping off the public $1 at a time is what it should say!!!!!
