The move was probably way overdue, but since we still call these devices phones or smartphones, I was stubbornly keeping the phone app in my dock. The dock should really be reserved for your most used apps, since the 4 apps that fit in your iPhone's dock (possibly more if it's an Android) are visible and reachable on every home screen.

I finally spent a little time thinking about it and had to admit to myself that the phone app is not one of my top 4 used apps, and at least 50% of the times I use it I don't even need to open the app, because someone else is phoning me and I just have to answer. I also looked back through my call history and I talk on my phone no more than 5 times per day on average. I use my mail apps, iMessage and other messaging apps way more than that.

Where do you keep your phone app?
