NetM is a lightweight Android app that displays real-time upload and download speeds in a floating bubble overlay, helping you monitor your network usage effortlessly. The bubble is draggable, works over all apps, and automatically hides when there is no active network connection.

NetM is perfect for users who want a simple, efficient, and always-on network monitor without draining battery or interrupting their workflow.
