Signal Lab

Seven tools that answer the questions a signal app usually leaves to guesswork: how far will this reach, where is coverage actually weak, how does traffic get out when the direct link dies, is the connection really working right now, which channel is clear, and what am I allowed to transmit here. Everything runs on the device — no extra hardware.
