    4G WiFi Maps & Speed Test. Find Signal & Data Now.'s review

    Open Signal Maps is a world wide project to map signal sources.

    • Free
    • Crowd sourced world wide project
    • It's quite a useful app
    • Battery draining

    "Where's my nearest tower?"

    Please, first at all check Open Signal Maps homepage.

    This app looks for the nearest towers around you. It's really useful if you are in a place nearly out of range and you need to know which way you have to walk toward in order to get better signal. In a populated city, where at least two or three towers are around you at any time, it's more a curiosity than anything else.

    When you activate this app, you're collaborating with Open Signal Maps, a project to map all the cellphone signals worldwide. Useful if you plan to travel to God-knows-where and you don't know if there'll be 3G there or not, or which carriers work and so on.
