No signal? Find the nearest place that has it.
LastBar is a map of mobile network coverage, built from the readings of everyone who uses it. It works with no connection at all, and points you to the nearest spot where your network, or any network, has signal.
Coverage per network
See where each carrier has voice, 3G, 4G and 5G, measured by phones on the ground and not taken from a carrier's own map.
Works offline
The map for your area is saved on your phone. Out of range, it still shows the coverage around you and guides you by distance and direction.

No account and no phone number. Readings are combined into map cells, and you can delete your contributions at any time.
