Beacon: Free WiFi Analyzer Seeking Testers

Beacon is a free, ad-free WiFi analyzer for Android that provides signal strength, identifies the least-crowded channel, and maps nearby networks to help users fix home WiFi dead spots. The app is currently in closed testing and requires additional testers to meet Google Play's requirements. Testers are asked to join the Google Group first, then use the provided opt-in link. In return, the developer offers reciprocal testing of other apps, including daily usage and feedback for at least a week.
