A weak mobile signal results in missed calls and decreased battery life as your phone boosts power to compensate. OpenSignal's multi-purpose dashboard shows you at a glance the quality of your data and voice connection and the location of nearby cell towers. A signal compass tells you which direction to walk in if you're experiencing problems or where your nearest free WiFi is. Additional features include speed tests and usage stats. Available for FREE on iPhone & Android, see: http://opensignal.com/
