What is Kindroid OTA app in Android 2.3?
What is its use and what is its over the air update?
there is no app.... just go to settings and check for updates, although you should get notification if there is an update for your device
It's probably an app that provides OTA (over-the-air, no computer needed) software updates for your phone/tablet (a Kinpad maybe?).
Over-the-air software updates are delivered straight to the device over Internet or other types of networks, without the use of a computer.
