Signal AR vs Sensor Viewer

Signal AR is a network analysis and visualization tool that helps you understand Wi-Fi and cellular signal quality in the real world. Scan your surroundings as you walk and see signal strength mapped into physical space using AR. Instantly identify weak spots, dead zones, and coverage changes—without relying on confusing numbers alone. Signal AR also provides signal history, charts, and performance insights to help you compare locations and improve connectivity at home, work, or on the go. Designed with privacy in mind, all data is processed and stored locally on your device. No ads, no accounts, no tracking. Whether you’re optimizing Wi-Fi placement or exploring signal behavior in different environments, Signal AR makes network quality visible, intuitive, and easy to understand.
