Do you know any alternative Android apps for Air-droid?
Android mobile manager, download both apk on phone and program on computer. Then you can manage your devices via wifi.
Android Assistant, Android Manager, Samsung Kies, htc sync…
As i know: Kies Air, Airmore
Airmore and Kies Air are best as I have used them both. That’s why I will recommend both apps.
HTC Sync Manager if you owned an HTC phone. Or Android Assistant if you backup data frequently.
I recommend Android file transfer and Android Assistant. 
The Android Assistant and Android data Manager are good at manage phone data , what is more , they are able to solve the Android data loss ,and it helps us transfer data from phone to other phone
I used both Android Assistant and Kies Air. I’d say they both work well. I preferred Kies, due to the reason I was using it. But it is personal preference at this point.
