Am I missing something? – iScape: Landscape Design Review

Found this app through a story in the App Store where it was advertised as free for homeowners. I added one ground cover and one retaining wall and it won’t allow me add more items. When I press the (+) to add an item the upgrade to Pro screen pops up. Every.single.time. The Pro version is $99.99 a year?! Is there a real free version somewhere that I missed?
