what3words: Navigation & Maps

Analysis by Getfullapps

I like navigation tools that solve a specific problem rather than trying to replace every app on my phone. what3words takes that approach by giving locations a three-word address, which can be useful when a normal street address is too broad, confusing, or simply unavailable. It is a free Maps & Navigation app from what3words, available for everyone, and it has become a widely recognized option with over 10 million installs.

My experience with it is best summed up this way: it is not a complete replacement for Google Maps, Apple Maps, or another conventional navigation service. Instead, it works as a precise location-sharing layer. You use it to identify a particular spot, then rely on an appropriate navigation tool to help you reach that spot. That distinction matters, because the app is most valuable when the final destination is a field entrance, a meeting point, a remote viewpoint, a festival area, or another place where a postal address does not point to the exact place you mean.

How the three-word address works in everyday navigation

The central idea is simple. The world is divided into small squares, and each square is represented by a combination of three words. Rather than telling somebody to meet “near the north side of the park,” I can share the three-word location for the precise area I have in mind. The recipient can open it in the app, see the point on the map, and use it as a destination.

That sounds like a small change from dropping a map pin, but it solves a real communication problem. A pin can be awkward to describe verbally, easy to place slightly incorrectly, and difficult to recognize when several people are sending different locations in a busy chat. A three-word address is easier to read aloud and can be copied into a message without requiring a long string of coordinates.

One realistic example is meeting friends at a large outdoor event. Saying “meet by the second entrance” may be unclear if the venue has several paths and temporary signs. I can stand at the exact meeting point, open the app, and share its three-word address. Another person can use that location as a reference even if the venue’s official street address only leads to the general grounds.

The same approach can help with rural walks. A trailhead, gate, picnic area, or viewpoint may not have a conventional address at all. In that situation, the app gives the place a compact identifier that is more practical to share than a long latitude-and-longitude pair. It is particularly handy when several people need to arrive at the same small area rather than merely the same road.

There is also a useful distinction between finding a place and navigating to it. The app is strong at expressing the exact destination. It does not automatically make every route easier, especially when the final point is off-road or inaccessible by car. I would still check the surrounding roads, paths, entrances, and local restrictions before setting off. A precise map square tells me where the intended point is; it does not guarantee that I can approach it directly from every direction.

Sharing a location without relying on a full street address

The sharing workflow is where I see the clearest practical benefit. Instead of explaining a location through landmarks that may change, I can share the three-word address itself. This is useful for delivery instructions, outdoor activities, temporary gatherings, and emergency-style location sharing where clarity matters more than a polished postal address.

It can also reduce misunderstandings between people using different mapping habits. One person may prefer Apple Maps, another may use Google Maps, and a third may only want a written location. A what3words address gives everyone the same starting point. They can open the location in the app and then choose the navigation method that suits them.

For a business or organizer, the system can be useful when a large property contains multiple entrances or service areas. A general address may bring somebody to the right building but the wrong gate. A specific three-word location can identify the loading area, visitor entrance, pickup point, or outdoor meeting zone more clearly.

Still, I would not use it as the only information in a message when the location has safety implications. I would include the nearby road, landmark, or entrance as well. The three words provide precision, while ordinary directions provide context. That combination is more reliable than treating any single location format as perfect.

What I would check before trusting the destination

The most important habit is to inspect the point on the map instead of blindly following the words. If the location is beside a river, behind a fence, inside a private property, or on a footpath unsuitable for vehicles, the map view should reveal at least part of that context. I would also compare it with the sender’s written description. If the words indicate a park entrance but the map point lands in the middle of a nearby road, I would ask for clarification before leaving.

This is one of the app’s less obvious trade-offs: precision can create false confidence. A very exact-looking destination may feel more trustworthy than a vague address, but it still depends on the point being selected correctly and on the recipient understanding the surrounding environment. The app improves location language; it does not remove human error.

For walking routes, I would use the three-word address to identify the endpoint and a normal navigation app to evaluate the route. For driving, I would pay special attention to the final approach. If the destination is on private land or a narrow trail, the safest route may end at a nearby public access point rather than at the exact square itself.

How it compares with pins, coordinates, and normal addresses

Compared with a dropped pin, a three-word address is easier to pronounce, remember briefly, and communicate by voice. That makes it attractive when somebody is giving directions over the phone or when a message needs to be read quickly. A pin remains excellent for visual sharing, though, especially when the recipient already understands the map and can verify the location at a glance.

Compared with latitude and longitude, the three-word format is much friendlier for ordinary conversation. Coordinates are precise, but long number sequences are easy to mistype or mishear. They are still valuable for technical, scientific, and professional workflows where numerical location data is expected. I would choose coordinates when interoperability and technical precision matter more than convenience.

Compared with a normal street address, the app has its strongest advantage away from conventional buildings. A house, shop, or hotel usually already has an address that people recognize and that navigation services handle well. In those cases, adding a three-word address may be unnecessary. The real gain appears when the destination is a particular point within a larger place or somewhere without a useful postal label.

The app is therefore complementary rather than competitive. I would use a standard map for route planning, traffic awareness, and turn-by-turn guidance, then use the three-word address to make the destination more exact. If I only need to find a named business on a normal street, the usual map application is likely faster. If I need to describe one exact point in a broad or informal area, this tool becomes much more compelling.

Cost, free access, and where value should be judged carefully

The app is free to download and use as a Maps & Navigation product, which makes trying the basic concept low-risk. That matters because its usefulness depends heavily on the places I visit and the people I need to coordinate with. I would not want to pay upfront simply to discover that my everyday destinations already have perfectly adequate addresses.

There are in-app purchases listed from $4.69 to $39.99 per item. I would treat those purchases as optional value rather than assume they are necessary for ordinary location sharing. The free entry point is the important part of the decision: I can test whether the three-word system fits my routine before considering any paid option.

Because the purchase range is broad, I would look closely at the exact item and its purpose inside the app before spending money. The price alone does not tell me whether a purchase is useful for occasional personal navigation, regular outdoor planning, or a more demanding workflow. In practical terms, the free experience is enough to decide whether the concept solves a problem I actually have.

The app has an average rating of 3.4 from around 47 thousand ratings, alongside hundreds of written reviews. I read that as a sign to keep expectations realistic rather than as a reason to dismiss the idea. A specialized location format can be extremely useful in one situation and feel unnecessary in another. Ratings may reflect that difference, as well as individual expectations about what a navigation app should do.

Small workflows that make it more useful

My preferred workflow is to save the location in two forms: the three-word address for precise sharing and a nearby ordinary landmark for orientation. For example, I might tell someone to enter through a named gate and then give the three words for the meeting point inside. This avoids the common mistake of sending an exact point without explaining how to reach it.

For group plans, I would send the location before people start travelling, not while everyone is already searching in a crowded area. Recipients can open it in advance, check the surrounding roads, and decide whether they need a separate navigation app. This is more dependable than assuming that every person will understand the location immediately in a noisy or low-attention situation.

For recurring outdoor spots, I would keep a personal note with the three-word address and a short description of access conditions. The words identify the square, while the note can remind me whether the point is reached from a car park, a footpath, a gate, or a particular side of a building. This pairing turns a memorable location code into a more useful practical instruction.

Another good use is separating the public destination from the exact operational point. A business might have a public entrance on one side and a delivery entrance elsewhere. Sharing the correct three-word location with the relevant person can prevent them from circling the property, but I would still include the entrance name and any access instructions separately. Precision is most helpful when it is combined with the information a visitor needs on arrival.

Where the app can create friction

The biggest limitation is adoption. A three-word address only helps if the recipient understands what to do with it. Someone unfamiliar with the system may see three ordinary words and wonder whether they are a landmark, a code, or a mistaken message. In a group chat, I would explain briefly that the words identify an exact map square and include the app name so nobody treats them as a casual description.

There is also a learning curve in deciding when to use the system. If I use it for every destination, messages can become more complicated than necessary. A normal address is often better for a restaurant, office, or home because it is already recognized by navigation apps, delivery services, and people. The three-word format earns its place when ordinary addressing loses precision.

Another limitation is the gap between a point and a route. A map can identify a square in a field, but a driver may need a legal road, a walker may need a marked path, and a visitor may need permission to enter. I would never interpret the exactness of the address as permission to cross private land or as proof that a vehicle can reach the point.

Offline or weak-connectivity situations also deserve caution. I would prepare important destinations before travelling and keep additional directions available rather than relying on a single app at the moment they are needed. This is sensible for any digital navigation tool, but the risk feels more noticeable when the destination is remote and lacks a conventional address.

Who will get the most value from it

I think the strongest audience is people who regularly meet others in large, open, temporary, or poorly addressed places. Hikers, campers, event visitors, photographers, cyclists, outdoor instructors, and families arranging pickups can all benefit from a concise way to identify one exact point. It is also useful for people who often give directions by phone and want something less error-prone than a long coordinate string.

It can be valuable for small organizations that need to communicate several points around one site. A property with multiple access areas, a community event spread across open ground, or a service team working at a precise outdoor location may find the format clearer than repeating a broad street address. The benefit is strongest when the same kind of location confusion happens repeatedly.

I would recommend trying it to anyone who has ever told a friend, “I’m near the entrance, but I don’t know which one,” or “The map brought me to the road, but not the actual meeting point.” Those are exactly the situations where the app feels more useful than its minimal interface might suggest.

On the other hand, I would skip it if nearly all my travel is between standard addresses and I already have a dependable mapping routine. I would also avoid making it my sole navigation solution if I need advanced route planning, detailed traffic decisions, transit information, or specialized professional mapping tools. Its value is in precise location identification, not in replacing every navigation feature.

My buying decision after using it

For me, the free access makes this easy to recommend as a companion app. I would install it if I attend outdoor events, share rural meeting points, coordinate pickups at large venues, or need to describe exact places that do not have useful addresses. I would use it alongside a normal navigation app, not instead of one.

I would be more cautious about paid purchases. Since the app can be tried without an upfront charge and the in-app items vary in price, I would only consider spending money after identifying a specific recurring need. Occasional users may get all the value they need from the free experience, while frequent users should judge a purchase by the time or confusion it saves in their own routine.

My final verdict is positive but deliberately narrow: this is a smart location-sharing tool, not a universal map replacement. Its three-word addresses make exact points easier to communicate, especially in places where street addresses and landmarks fall short. The trade-off is that recipients need to understand the system, routes still require common sense, and ordinary destinations may not benefit at all.

If you want a clearer way to say exactly where to meet, the app is worth trying. If you want the most complete turn-by-turn navigation experience, I would stay with your usual map and use this as an extra layer when precision matters. Its real value is not getting you everywhere; it is helping everyone agree on the same small piece of the map.
