This is the best of the bunch on this platform. If you have any experience with the competition, you may think thats not a difficult feat to accomplish. While its true that being the best of a bad bunch isnt terribly tough, the care and dedication that went into this app puts it atop a pile of far more competent contenders than it currently has.
