Pulse is a video chat app, allows you to meet new friends globally, anytime and anywhere, with just a single swipe. I joined Pulse from the MVP version, with basic fundamental features, and on the way for developing the new and improving the current. It's such a pleasure to join Pulse, experience different research methods, learn a lot from my findings, and evaluate if my solution works. If this is the first time you heard about "Quantitative vs Qualitative Research", or "System Data Analyze", this Case Study is definitely for you.
