I found a free map app that works with no signal — and no subscription

I have a simple test for navigation apps now: what happens when my phone stops pretending mobile data is a human right? A lot of maps are brilliant until the signal drops, the road gets weird, or I’m trying to conserve data because data roaming is still something travelers have to think about, usually while pretending not to cry at the bill.

That frustration is what led me to Organic Maps, an app that turned out to be refreshing precisely because it does something unglamorous extremely well. Download the map ahead of time, open it later, and it just works, signal or not. Google Maps can do offline maps too, and one Google Maps setting makes offline navigation dramatically better, but Organic Maps feels built around that idea rather than treating it like emergency rations.

The best map app sometimes remembers what maps are for

Satellites don’t need your phone plan

Organic Maps is an open-source offline navigation app for Android and iOS, built on OpenStreetMap instead of Google Maps data. Two of the original MAPS.ME developers, Alexander Borsuk and Viktar Havaka, started the project as a fork in late 2020, after MAPS.ME’s new owners took the app closed-source and leaned harder into ads and monetization. Organic Maps had its first public release in June 2021, built around offline-first navigation as the core design rather than a fallback for bad reception.

That changes how the app feels in daily use. I download the regions I need inside the app, whether that is an entire country or a smaller area I know I will be moving through, and once the map is saved, Organic Maps has very little reason to keep checking in with the internet. I can search for addresses, street names, and points of interest offline, plan routes, and get turn-by-turn voice guidance for driving, cycling, or walking without burning through mobile data or depending on a signal at the exact moment I need directions.

Privacy is one of the strongest reasons to care about Organic Maps. A navigation app, by design, knows where I’ve been, where I’m going, and how often I go there. Organic Maps says it does not collect that data or track location history, which stands out in an app category built around valuable behavioral information. Its Android build has been checked by the Exodus Privacy Project, a tool that scans apps for embedded trackers. That is far more useful than simply taking a developer’s privacy claims at face value.

There is an asterisk worth knowing about, though. Organic Maps’ image as a community project free from corporate pressure became more complicated in 2025, when part of the community forked the project over concerns about governance, transparency, and the possibility that shareholder profit-taking would prioritize contributors. That split led to a separate project called CoMaps, an open-source Google Maps alternative.

The dispute started with an open letter from community members to the project’s shareholders in April 2025, and when it wasn’t resolved to their satisfaction, a group of contributors split off to build CoMaps independently. There’s an actual company behind Organic Maps, registered in Estonia, with shareholders. That doesn’t undo anything I said about tracking and data collection, which still checks out. But it’s worth knowing the “community project” pitch isn’t as simple as it sounds, and that an alternative exists if the governance question matters to you.

There is also a second wrinkle. Organic Maps remains open-source software, but as of August 2025, the map data it uses is distributed under a custom license, and the tooling used to generate that data is no longer publicly available. The app’s code is still open, but the map files underneath it are now a little less open than they used to be.

Offline maps are not magic, but they are a very good Plan B

Offline navigation rewards people who prepare

Data quality depends entirely on what’s been mapped. And so, Organic Maps is only as good as the OpenStreetMap data that volunteers have contributed, and that varies by region. Cities, popular hiking trails, and well-mapped countries tend to be detailed and accurate, sometimes turning up trailheads or footpaths that commercial map apps skip entirely. Other areas, particularly less-traveled rural regions or fast-changing commercial districts, can be thinner. That same trade-off applies to other offline-first tools too, including apps like OsmAnd, another free navigation app that works offline.

Business hours and new storefronts depend on volunteers keeping the data current, so it’s not the tool I’d trust to confirm a restaurant is open right now. Live traffic, real-time transit, and ride-hailing integration aren’t part of what this app is trying to do.

Storage is a minor consideration, too. Regional map downloads range from a few megabytes for small territories to several gigabytes for a region as large as the United States, so it’s worth being deliberate about which regions actually matter for a trip rather than downloading everything in sight.

I’m not replacing Google Maps, and I don’t need to

For when the internet leaves the group chat

I am not uninstalling Google Maps, Apple Maps, or Waze to make a philosophical point. That would be performative and inconvenient, which is a terrible combination. Google Maps is still better when I want live traffic, dense business information, reviews, photos, routing in crowded cities, and quick answers about places that change daily. Waze is still built around road conditions and driver reports. Apple Maps has improved a lot, especially if you live inside Apple’s ecosystem.

Organic Maps earns its place by doing a different job. It is the offline layer I want installed for road trips through patchy coverage, hikes where I don’t want to burn the battery searching for signal, international travel where I’d rather not pay for roaming data just to find my hotel, and any situation where a network connection shouldn’t be a requirement for finding my way somewhere.

It also has the small features I’d actually want from a map like this. Bookmarks are there, and they work offline. Tracks can be imported and exported in formats like GPX and KML. Search categories include everyday places like ATMs, cafés, bus stops, bicycle parking, bookstores, and campgrounds. There are map styles and layers for outdoor use, contour lines, hiking, cycling, and public transport views. The settings are plain enough that I can adjust measurement units, voice instructions, power-saving mode, search history, and location service behavior without decoding a product manager’s ambitions.

Free, Open-source

Organic Maps is a free, open-source, offline navigation app for hikers, cyclists, and travelers. Built by Maps.Me founders using OpenStreetMap data, it features detailed maps, routing, contour lines, and voice guidance without cellular data. It prioritizes user privacy, containing zero ads, tracking, or data collection while remaining highly battery-efficient.

Organic Maps is a free map app with survival instincts

Organic Maps won’t replace every modern mapping feature, and it doesn’t need to. When the signal disappears, it doesn’t turn into a blank rectangle in my hand, and for a free app with no subscription, that’s enough to keep it installed.
