It's easy to forget, but smartphones are supposed to be phones. Shocking, I know. Ignoring this most basic of functions is no good, though. Ready Contact List for Android can make your calls more efficient and attractive, and it's out of beta today.
Ready takes over for your standard dialer and incoming call screen to offer smart shortcuts when a call comes in and when it's over. For example, you can add a meeting to your calendar with the person you just talked to in a few taps. It also has a neat contact card system with lots of Gaussian blur. The app is rather nice in the looks department with splashes of bright color and cool animations.
The basic features are included for free in Ready Contact List, but you'll get nag messages at the bottom of the screen suggesting you upgrade to pro. The full package is currently $2.99 and adds themes, a predictive dialer, more ringtones, and removes the ads. Each of the features can also be purchased individually, but that's not a very good deal.
