My friend Kyle Ryan and I spent months researching the dearth of quantitative and qualitative feedback prevalent in modern technology platforms. As engineers learning the mobile iOS platform, our mission became:
Build a system that makes it easy for people to get feedback in order to make better decisions.
We did research on feedback pools and eventually delved down the path to solving three major findings: using gestures to provide feedback easier, building a novel feedback interface, and visualizing results that could be understood at a glance.
