Mobile Signal Finder app for iPhone and iPad

Use Mobile Signal Finder to test your network connections. Initiate mobile or wifi speed tests with a single tap. Browse a chronological history of your download and upload speeds. See your test locations on an interactive map. Tap on a location pin to see the average jitter, ping, download and upload speeds recorded at that location.

Activate the crowdsourced coverage map to view signal strength performance from various network operators. Filter the map by operator and network type (2G, 3G, 4G, 5G). Check to see if your operator has the best performance in your area. Toggle between heat maps of the top operators in any area. Know before you go; find out if your operator will have strong cellular service at your destination. Determine the best SIM needed when traveling internationally.

A robust database enables us to provide all Mobile Signal Finder community members our crowdsourced network coverage map. Members contribute readings from various locations and network operators. The more contributing members we have, the more complete and precise our crowdsource map becomes.
