No bars? LastBar shows you the nearest place where your phone will work, and the nearest water and shelter. A coverage map made by its users, with no connection. 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. Phones note the signal of their carrier at the places they pass. 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 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 to do so. 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 a number to call, where there is one. 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 someone was there and had no signal at all. Tap a place for its signal, 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. Search for a town or a country by name. WORKS WITH NO CONNECTION LastBar is made for the places where you need it most, which are the places with no signal. 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 If you agree to contribute, LastBar takes a reading every few minutes while it is open: where you are and how high, and the kind of network your iPhone is on. Your readings show on your map at once, are kept on your phone first, and are sent when you have a connection again. 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 are never shared with advertisers. Stop contributing at any time, and delete everything you contributed from within the app. YOUR LOCATION LastBar asks for your location while you use the app, and for nothing more: to show where you are on the map, to guide you to signal, and for the place of a reading. It takes no readings while it is closed. You can use the map without giving your location at all. 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, 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 with the app open fills it in, for you and for everyone after you. Where there are no readings, LastBar can show the estimated position of towers instead, as an estimate. An iPhone tells an app the kind of network it is on and not how strong the signal is: the strengths on the map were measured by phones that can. Coverage changes, and a reading says what was, not what will be. Water, shelters and the other points were mapped by volunteers: one may be wrong or gone, water is not always safe to drink, and not every country has them yet. In an emergency, call your local emergency number. Map data and points of interest © OpenStreetMap contributors. Tower locations © OpenCelliD, CC BY-SA 4.0. Published by CLC Agency.

Ratings & Reviews

  • This app hasn’t received enough ratings or reviews to display an overview.

Help where there is no signal: the map has a "POI" layer with water, shelter, huts, clinics, police, fuel and peaks, from OpenStreetMap, kept on your phone with your saved areas. Find Signal points you to the nearest water or shelter too. Search the map for a town or a country. Your saved areas are marked on the map and can be refreshed. The map shows all carriers until you pick one. A free saved area is as large as one of Pro. Stats counts your speed tests.
