I honestly didn’t know which app to buy. I wanted to believe that the lower priced one was the real one, but it turned out it wasn’t. I dug into the version history and found that the clone was a 1.0 version launched on December 20th of this year. The real one had a long history of steady updates. Bingo! I finally knew which one to get.
I remember back in 1997 when Pontiac debuted their new Grand Prix sedan, they provoked BMW’s ire. The problem was that BMW felt that Pontiac was infringing on their trademark “twin kidney” look for the grill, so they sued. Pontiac’s grill did kinda sorta look like BMW’s, but they ultimately prevailed in court. My point is that in the manufacturing world, you don't have free reign to blatantly make money from someone else’s design.
