Air Call Answer is a free Android app developed by App Basic. It falls under the category of Social & Communication apps. With the use of the in-built proximity sensor, this app allows users to easily answer or reject phone calls without having to touch their devices. By simply swiping their hand gently over the screen, users can attend or ignore calls.

One of the standout features of Air Call Answer is the new Light Sensor feature. This feature prevents auto-answering of calls when the phone is inside the user's pocket. The app alerts the user if their device does not have a light sensor or if it is not supported.

Additionally, Air Call Answer enables touch-free answering of calls by simply putting the phone near the user's ear. The app utilizes the proximity sensor of the mobile device, allowing users to answer or reject calls by waving their hand over the screen. This feature is especially useful for hands-free calling while driving or when the phone is placed on a dashboard.

Overall, Air Call Answer offers an effortless and intuitive experience for touch-free call answering. With its utilization of proximity sensor technology and low battery consumption, this app makes answering and rejecting calls a much easier task. Users can also share their experience with the app through the Facebook sharing feature.
