Reckon App / Reckon.nu is the coolest and easiest way to rate anything at all. Reckon was founded in 2012 in Amsterdam by the crew of the popular weblog recensiekoning.nl. The pilot version was launched in the summer of 2012 at the national annual music festival Lowlands and was immediate picked up by a few thousands users.
I have implemented the Android version of the Reckon app. The goal was to make the app as close as possible to its iPhone equivalent. Furthermore, the app integrates with the Facebook SDK for Android to provide a seamless user experience.
