AirDroid for Android has been given a major update in v3.0. The app now has companion desktop apps for Windows and Mac that brings iOS Continuity like features to your Android device.
With the new desktop app, you can get notifications from your phone on your computer. You can reply to SMS from your computer or pick up or receive calls (calls can only be answered from the phone, however). You can also mirror apps on your computer, so you can, for example, reply to WhatsApp messages from your PC. Mirroring apps only works on rooted devices for now.
As before, you can also transfer files between your computer and mobile device. There are some file size restrictions depending upon the plan you choose.
You can download the Android and desktop apps from the links below.
