Hrishi Mittal- Founder, Learnetto.comI've been using Geckoboard for years and love it. It's simple, looks nice and connects to pretty much everything. When it doesn't directly connect to an app, there are easy workarounds using Google sheets. It's also been designed for putting up displaying dashboards on screens around your office.
