How accurate is this coverage map?

It reflects carrier-reported modeled coverage published by the FCC (data as of Dec 31, 2025). It is not an onboard measurement. BarTrakr shows the FCC's in-vehicle model by default; the outdoor model is available with the Outdoor switch.

Can I use BarTrakr on the train without signal?

Yes. Tap “Save for offline” before you board. The route, coverage data and map background up to zoom 10 are stored on your device, and live tracking uses your phone's GPS, which works without cell service.
