What is it?

Traffic Light is an Android app that shows how much network data your device uses over time. It tracks data plan consumption, including setups with multiple SIM cards, and keeps in-depth historical records so you can see usage trends rather than just a current total.

The app offers home screen widgets, a network indicator in the status bar, and at-a-glance usage analytics. The project positions itself as privacy-respecting and states that it uses less battery than comparable tools. It is inspired by Internet Speed Meter and GlassWire.

The app is available through F-Droid, Obtainium and the Google Play Store. The Play flavor omits multi-SIM support, which requires Shizuku in the Full flavor.
