It is not a marketing trick Apple purchased the company and have supplied a much more advanced BETA version built into the iphone4s One can expect to see a far better version be made available some time in the future that will rum on iPads and iPhone 4. So be patient. You will find that if a developer is purchased by another company as in this case Apple that company has the right to remove any updates or apps and provide a new product.... If you did pay any money for the App then you. Old ask for a refund but I believe the App was free in the first place.
