Android: If you're on a limited data plan, or if you're just watching your battery life, you sometimes want to peek at how much data your Android device is using. NetLive keeps things simple, and puts the essential data in your notification drawer.
Once you install the app, it puts a permanent banner in your Notification Drawer that displays the app currently using the most data, and your device's total upload and download bandwidth. This is great if you notice your battery draining too quickly, and want to quickly figure out which process is misbehaving.
There are a lot of data usage trackers available on Android, most of which offer a lot more features than NetLive. However, for getting a quick glance at your network activity, NetLive is tough to beat.
