Episode 2 of The Verge - Joanna Stern showed an app that opens a website from the taskbar - what was it?

As per the title really. In episode 2 of The Verge - Joanna Stern showed an app that opens a website from the taskbar, it looked like a small arrow pointing upwards - what was it called/where is it available? My hearing is terrible and I think I hear her say something like "cookies" or "pookie" or somesuch!
