With the launch of the Galaxy Nexus, there's a good chance that many users left their current carrier to go with Verizon. Since Big Red no longer offers unlimited data plans, keeping tabs on your data usage is an absolute must. For that, Onavo is here to help, and the most recent update to its app makes monitoring your usage even easier.
The new widgets include App Watch, which helps you keep track of how much data is being used an a per-app basis; a data plan used widget, which offers a quick look at where you're at for the month (with percentage used); and a live data usage 1x4 that shows how much data you've used in the last 30 minutes.
The app is free in the Market, hit the widget to grab it.
