LastBar

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 network every few minutes. Those readings become a map of where there is signal and where there is none, carrier by carrier. When you are stuck, the map is already on your phone.

FIND SIGNAL
Choose what you need: an emergency call on any network, 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 to do so.

A MAP FOR EACH CARRIER
See the coverage of your carrier, or the best of all of them. 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 someone was there and had no signal at all. Tap a place for its signal strength, its download speed, how many readings it has and how recent they are, for its altitude, and for its coordinates, to copy or to share.

WORKS WITH NO CONNECTION
LastBar is made for the places where you need it most, which are the places with no signal. 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 and its coverage 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 and what you found there.

ANONYMOUS
There is no account and no sign-in. LastBar never reads your phone number, your contacts or your calls, and uses no advertising id. Your phone gets a random id that says nothing about you. Readings are combined into map cells before anyone sees them. Stop collecting 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 with the settings it comes with. Choose how often it takes a reading, whether it collects in the background or only while the app is open, 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 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 and lets you save 10 areas where there is one.

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. Where there are no readings, LastBar can show the estimated position of towers instead, and says that it is an estimate. Coverage changes, and a reading says what was, not what will be. In an emergency, call your local emergency number.
