If one could point toward any field of apps which is particularly saturated in terms of numbers, it’s fair to say the Photography section bears the crown. Thanks in part to the popularity of Instagram, there are literally thousands out there, and while this is good for the snap happy smartphone and tablet users out there in terms of sheer choice, but it also means quality is enhanced as developers seek new ways to gain recognition. Krop Circle is charmingly different from the vast majority of photo apps out there, offering circular crop overlay from which you can take shots, and when used in certain environments, it can produce some spectacular results.
