iBearSoft is an iPhone app developer. When I wanted a finance tracking program, I saw that their "Money" app was highly rated and bought it. After a couple of days, I deleted it because it was horribly written and simply didn't work correctly. That's when I went back and looked a little more closely at those glowing reviews and concluded that iBearSoft wrote all of them.
Weird grammar coincidences
The iBearSoft developer apparently is not a native English speaker. Because of that, you can find several characteristic spelling and grammar mistakes repeated throughout the descriptions of his applications, such as unusual punctuation, mixing singular and plural forms, and using both American and UK spellings. The interesting thing is that the highest-rated reviews tend to have the exact same mistakes!
