One of my hopes for apps in 2015 was that apps would continue to interact each other and behave in a seamless way. Spotify4Me takes what is playing in Spotify and display it in your notification center, allowing you to stay focused on your current application instead of switching between apps.
2014 brought about a lot of great changes: Android Lollipop, iOS 8, OS X Yosemite, and the public beta of Windows 10. Hopefully we will see each system used to its full advantage in 2015. With the many new features available to developers within those systems, we should say many creative apps pop up. Here is what I hope to see in 2015.
