App dialer allows you to "dial-in" the app you are looking for
iOS has a handle on that with the Spotlight Search function, which can not only search through your contacts, but also your apps, email, and others. Well, App Dialer is a new app for Android that takes a page off of that book and provides the user with a simple search function.
App Dialer looks like the normal phone dialer when launched. However, instead of showing you matching names from your contacts list, it will quickly match app names instead, and show you the results. Why the developer chose to go with a dialer, instead of a QWERTY keyboard, is unknown. However, a quick glance at the app's comments section on the Google Play Store tells us that he is thinking about adding a keyboard in the near future.
