Reviewing Google Maps is really reviewing two things at once: the best mapping dataset ever assembled, and the data-collection machine that funds it. Two decades of Street View imagery, business listings, transit feeds, and live traffic derived from millions of Android phones make it the navigation app everything else is measured against. It comes preinstalled on most Android devices and shows up in more than ten billion installs.
Nothing here costs money, and that is the point worth pausing on. Maps feeds Google's advertising business through place searches, visited locations, and promoted pins, and by default a signed-in account records far more movement history than most people realise. The app has become more honest about this over time — Timeline data, for instance, is now stored on the device rather than on Google's servers — but the burden of configuring sane defaults still falls on you.
Driving in unfamiliar cities
Turn-by-turn navigation with live traffic rerouting is where the crowd-sourced data pays off most visibly. Lane guidance, speed-limit display in many regions, and hazard reports make it dependable enough that many drivers have stopped considering alternatives.
Public transport and walking
Transit directions cover schedules, platforms, and real-time delays in a huge number of cities, and walking mode includes an augmented-reality Live View for orienting yourself when leaving a station. Coverage quality varies by city, but the breadth is unrivalled.
Deciding where to eat
Place listings bundle reviews, photos, opening hours, busyness estimates, and menus. Review quality suffers from spam and rating inflation, yet the sheer volume of data usually gets you to a reasonable decision faster than any dedicated restaurant app.
Navigation for every mode
Driving, walking, cycling, transit, and combined routes all live in one app, with fuel-efficient routing options for drivers. Rerouting around incidents is fast and usually right, thanks to live speed data from other phones on the road.
Offline maps
Selected areas can be downloaded for offline driving navigation and search. The limits matter: downloads expire and need refreshing, transit and cycling directions are unavailable offline, and coverage of some countries is restricted. Fine for a trip, not a full offline solution.
Street View and immersive imagery
Ground-level imagery for much of the planet lets you scout a parking entrance or hotel front before arriving. It remains genuinely useful in a way few features from 2007 still are, and no competitor matches its coverage.
Timeline
If enabled, Timeline reconstructs everywhere you have been, day by day. Following a major 2024 change it is stored on your device with optional encrypted backup, and Google says it can no longer serve location data from Timeline in response to broad law-enforcement requests.
