Find mobile signal when you have none. A coverage map made by its users.

No bars? LastBar shows you the nearest place where your phone will work.
LastBar is a map of mobile coverage made by the people who use it. As you travel, your phone notes the signal of your carrier every few minutes. Those readings become a map of where there is signal and where there is none. When you are stuck, the map is already on your phone.
FIND SIGNAL
Choose what you need: an emergency call on any carrier, a call or SMS on your own, or data. LastBar gives you the distance and the direction to the nearest place that has it, says whether it is higher or lower than you, and turns with your compass as you go. It needs no connection.
WATER, SHELTER AND HELP
Far from anything, the map shows water, shelters, huts and caves, clinics and hospitals, police, fuel and peaks, from OpenStreetMap. Tap one for its address and its phone number. Find Signal points you to the nearest water or shelter too.
A MAP FOR EVERY CARRIER
See the coverage of all carriers at once, or pick your own. Show any signal, voice, or data on 3G, 4G or 5G. Green is strong, orange is fair, red is weak, and an empty outline means no signal at all. Tap a place for its signal strength, its download speed, its readings and how recent they are, its altitude, and its coordinates, to copy or to share. Search for a town or a country by name.
SATELLITE MAP
With LastBar Pro, switch the map to satellite pictures and see the land itself under the coverage: mountains, rivers, fields and towns. Saved areas keep them offline.
WORKS WITH NO CONNECTION
LastBar is made for the places with no signal, where you need it most. What your phone measures shows on your map at once. The coverage around you is kept on your phone. Save an area before a trip to have its map, its coverage, its towers and its points of interest with you, offline.
YOUR OWN READINGS
Every reading is kept on your phone first and sent when you have a connection again. Your own readings are marked on the map, so you can see where you have been. The Stats tab says what you have mapped, day by day.
ANONYMOUS
There is no account and no sign-in. LastBar never reads your phone number, your contacts or your calls. Your phone gets a random id that says nothing about you. Readings are combined into map cells before anyone sees them, and never shared with advertisers. Stop at any time, and delete everything you contributed from within the app.
LIGHT ON BATTERY AND DATA
About 3% of a charge and 5 MB a day as it comes. Choose how often it takes a reading, and whether it uploads on Wi-Fi only.
LOCATION IN THE BACKGROUND
LastBar collects location data to map mobile coverage along the way you travel, even when the app is closed or not in use. A notification shows for as long as it collects, with a button to stop. You can use the map and Find Signal without it.
FREE, WITH ONE PURCHASE
The map, Find Signal, the points of interest and your own readings are free, and stay so. The free version shows one small ad, and never on Find Signal. LastBar Pro is one payment, with no subscription: it removes the ad, adds the satellite map, lets you save 10 areas where there is one, and keeps the coverage of more places on your phone.
GOOD TO KNOW
The map is as good as its readings. Where nobody has been with LastBar yet, it is empty: every trip you take fills it in, for you and for everyone after you. Coverage changes, and a reading says what was, not what will be. The satellite pictures are from 2016 and show the land, not single houses. Water, shelters and the other points were mapped by volunteers: one may be wrong or gone, and water is not always safe to drink. In an emergency, call your local emergency number.
