what3words: Navigation & Maps

When someone gives me a normal street address, I can usually find it. When they point me toward a specific entrance in a park, a meeting place on a beach, or a spot beside a large venue, the situation becomes less comfortable. That is where what3words earns its place. It is a Maps & Navigation app from what3words that identifies exact locations with a three-word address, giving people a simpler way to describe places that may not have a useful street number.

I have found the idea most useful when the destination is precise but the address system is not. Instead of trying to explain which gate, trail junction, or patch of open ground I mean, I can share the location’s three-word label. The app is free to download, suitable for everyone, and has grown to more than ten million installs. Its average rating is 3.9 from roughly forty-six thousand ratings, which feels like a fair reflection: the concept is genuinely practical, but it does not replace a complete navigation service for every journey.

What to consider before choosing it

Decide whether your problem is finding a road or identifying a precise point

The first question I would ask is not whether the app is clever, but what kind of location problem I have. If I need turn-by-turn directions across a city, a traditional maps app is usually the more natural starting point. Those services are built around roads, traffic, businesses, public transport, and route planning. what3words approaches the problem from the other direction: it gives a precise label to a point, including places that are difficult to name with an ordinary address.

That distinction matters. A three-word address is not automatically a complete journey plan. I still need a navigation tool, a driver, a walking route, or local knowledge to reach the point. The value appears when the final destination is hard to communicate. I see it as a location-sharing layer that can work alongside conventional maps rather than as a universal replacement for them.

Think about how other people will receive the location

A location format is only useful if the person receiving it can understand and use it. If everyone in a group already relies on a familiar mapping service, sending a pin may be faster. If the group is meeting somewhere without a clear address, the three-word format can be easier to repeat verbally and easier to check than a long description involving nearby landmarks.

This is especially helpful when a place has several entrances or when the obvious address leads to the wrong side of a building. Before sharing a location, I would make sure the three-word address points to the place I actually mean: the public entrance, the meeting area, the roadside pickup point, or the trail access. A tiny shift can be important when a large site has several possible arrival points.

Consider whether precision is more important than familiarity

Most people already understand a street name, building number, or dropped map pin. Three-word addresses require a small learning step. The words are designed to identify a very small square of land, so they are precise, but precision also means I have to choose the right square. That is a useful trade-off rather than a flaw, provided I take a moment to inspect the location before sending it.

I would choose this app when the destination’s exact position is the main concern. I would not choose it simply because I want another general-purpose map. The best results come from matching the tool to the communication problem.

My practical test for deciding

Before relying on it for an important meeting, I use a simple workflow. I search for the destination, inspect the surrounding area, identify the point where I want the other person to arrive, and then share that three-word address. I also include a short human explanation when the situation calls for it, such as “use the north entrance” or “wait beside the parking area.” The app supplies precision; a few ordinary words supply context.

That combination is one of the less obvious strengths of the service. A precise location code does not tell someone whether a gate is open, whether a path is suitable for a wheelchair, or which side of a road is safe for pickup. Adding practical context prevents the three-word address from being treated as a magic substitute for local awareness.

Where it wins in everyday use

Meeting people at places without useful addresses

The clearest everyday scenario is a group meeting in a place that does not have a conventional address. Imagine arranging a picnic in a large park. Saying “near the lake” may leave several possible spots, while a street address may lead someone to the park’s main entrance rather than the blanket area. I can select the exact meeting point and share its three-word address, then add a sentence explaining which path or entrance to use.

The same approach works for outdoor events, beaches, campsites, rural properties, and large public grounds. In each case, the app helps separate the intended point from the broader named area. That is more useful than simply sending the name of a park or venue, because names describe destinations at a broad level while the three-word address identifies the particular place I have in mind.

Giving clear instructions to a driver

Pickup instructions are another strong use. A large venue may have several roads around it, and “meet me at the stadium” leaves too much room for confusion. I can choose the correct roadside point or entrance, share it, and then explain whether I am waiting inside, outside, or near a particular landmark. This is helpful for friends, taxis, delivery arrangements, and event groups, although I would still check local access and safety before asking a driver to stop.

The important detail is to choose a point that a vehicle can realistically reach. Selecting the exact spot where I am standing may not be useful if it is on a footpath or behind a barrier. For driving situations, I prefer to identify the nearest practical stopping point and use the written message to describe the final short walk.

Finding entrances rather than just destinations

One of my favorite uses is marking an entrance. A business, hospital, campus, or exhibition site can occupy a large block, and the building’s official address may not tell a visitor which door to use. A three-word address can be set at the entrance itself, which reduces the common problem of arriving at the right property but the wrong side.

This is also a useful habit for recurring visits. If I am meeting someone at the same complex several times, saving or reusing the precise location can be clearer than remembering a vague instruction. I would still verify that the entrance has not changed, especially at temporary events or construction sites, but the app makes the original instruction much less ambiguous.

Sharing a location by voice

Because the address consists of three words, it can be spoken more naturally than a long string of coordinates. That does not make verbal sharing foolproof. Similar-sounding words, background noise, accents, and spelling differences can still cause mistakes. I would repeat the words carefully and, when possible, send the location digitally as well.

This gives the app a useful role when someone cannot easily describe a place visually. A person can say three words over the phone instead of trying to explain a sequence of turns from a distant landmark. The recipient may still need another navigation app to complete the trip, but the destination itself becomes easier to identify.

Using it as a backup for places that are easy to overlook

There is a practical backup use that is easy to miss. If I am visiting a remote viewpoint, an informal trail access point, or a temporary gathering area, I can record the precise location before leaving. That gives me a reference to share later, even if the place has no memorable name. It can also help a group coordinate when different people arrive from different directions.

I would not treat this as a replacement for preparation. Outdoor travel still calls for checking routes, conditions, access, and battery life. The app is strongest at answering “which exact point do you mean?” It is not, by itself, an answer to every question about reaching or safely using that point.

Why the three-word system can be easier than coordinates

Coordinates are precise, but I find them uncomfortable to read aloud and easy to mistype. A dropped pin is visually clear when the recipient opens the same kind of map, but the meaning can become less convenient when people are coordinating across different tools or trying to describe a point verbally. Three words sit between those options: more exact than a broad address and more approachable than latitude and longitude.

That middle ground is the app’s real identity. It is not trying to make every map feature more powerful. It is trying to make a precise location easier for ordinary people to name and pass on.

Where a conventional map or another approach may fit better

For full route planning, the familiar option is often better

If my priority is choosing between driving, walking, cycling, or public transport, I would begin with a full navigation app. Those tools are generally more familiar for route planning and are designed around the journey rather than only the destination point. what3words can help define the endpoint, but I would not expect it alone to provide the complete experience I want for a complicated commute.

This is the main reason I would not recommend switching completely. The app solves a narrow problem very well, while conventional mapping services cover a wider range of travel questions. Many people will get the best result by using both: one to identify the exact destination and another to plan the route.

For simple addresses, it may add unnecessary friction

If I am visiting a clearly numbered building on a well-known street, a normal address is usually faster. Asking someone to install an app or learn a new location format for a straightforward destination can make coordination harder rather than easier. The benefit rises with ambiguity, not with every trip.

That is an important boundary. The app is not automatically better because it offers more precision. Extra precision only helps when the ordinary address is too broad, confusing, or unavailable. For a routine appointment in a clearly marked building, the usual address may remain the most convenient choice.

For people who dislike new location conventions

Some recipients may hesitate when they see three unfamiliar words instead of a street address. If a family member or colleague is uncomfortable with new apps, a conventional address plus a recognizable landmark may be more effective. I would not make the three-word format the only instruction when the journey is important and the recipient has never used it before.

A good compromise is to send the three-word address together with the ordinary place name and a short arrival note. That lets the recipient use the method they trust while keeping the precise point available if the broad description proves insufficient.

For changing conditions, context still matters

A location label identifies a point, but it does not automatically tell me about temporary closures, blocked paths, event layouts, weather, or access restrictions. If I am directing someone to a festival entrance or a remote meeting place, I need to confirm the current practical details separately. The app can make the point exact while the surrounding circumstances remain changeable.

This is where generic enthusiasm about precision can become misleading. Exact coordinates do not guarantee an easy arrival. I still need to think about the person’s mode of travel, mobility needs, safety, and the difference between the map point and the usable entrance.

Privacy and sharing deserve a deliberate decision

Sharing any precise location deserves care. I would avoid sending the exact point of a private home or a sensitive meeting place to a broad group unless there is a clear reason. The convenience of a precise address should not remove ordinary judgment about who needs to know it.

For public meetups, I usually prefer a public entrance or nearby meeting point rather than a private interior location. That keeps the instruction useful without revealing more detail than necessary. The app makes accuracy easy, so the responsibility to choose an appropriate point becomes more important, not less.

The cost of switching and fitting it into my routine

Starting is inexpensive, but learning takes a moment

The app is free, which makes experimenting with it relatively easy. It is rated for everyone, and it supports devices running Android 7.1 or later. I can try it without committing to a subscription-style decision, although in-app purchases are listed from about $4.69 to $39.99 per item. I would check the purchase screen carefully before confirming anything, especially if I only need the core location-sharing idea.

The real cost is not the download. It is the habit change. I need to remember when a three-word address is more useful than a normal address, choose the correct point, and explain the format to people who have not encountered it. Once a group understands the process, that friction becomes smaller, but it is still part of the decision.

A sensible transition workflow

I would not replace my usual maps app on the first day. Instead, I would use what3words for a few situations where ordinary addresses are clearly weak: a park meeting, a venue entrance, or a rural destination. I would send the three-word address alongside the familiar place name and observe whether the recipient can use it comfortably.

After that, I could make the instructions more focused. For example, I might send the three-word address first, followed by “this is the east entrance, not the main road.” That keeps the precise location and the human explanation together. It also makes it easier for someone to fall back to the normal map if they prefer.

What I would check before relying on it

For an important appointment, I would check four things: whether the selected point is physically accessible, whether it is on the correct side of the road or building, whether the recipient knows how to use the address, and whether I have a backup description. This takes little time and avoids the most common mistake, which is selecting a precise point that is technically correct but practically inconvenient.

I would also avoid assuming that the person receiving the address will understand the final approach automatically. A three-word address can remove uncertainty about the destination while leaving uncertainty about the route from the nearest accessible road. A short note about the entrance or last few metres often makes the difference.

Who should skip it

I would skip it as a primary navigation tool if I only need standard road directions, business searches, traffic information, or public transport planning. I would also be cautious if the people I regularly coordinate with are unlikely to install or use another location system. In those cases, a familiar maps service may create less friction.

I would not skip it entirely if I often meet people in open spaces, work across large sites, organize outdoor activities, or need to describe exact points without formal addresses. For those situations, the narrow focus is precisely why it can be valuable.

My recommendation after using it

I recommend what3words as a companion for precise location sharing, not as a blanket replacement for ordinary maps. Its strongest quality is the way it turns an awkward explanation into a compact three-word reference. That is meaningful when a street address is too broad, a landmark is vague, or a large property has several possible arrival points.

I especially recommend it for event organizers, outdoor groups, families meeting in parks, drivers collecting people at large venues, and anyone who regularly deals with places that do not have dependable street addresses. The most effective users will pair the three-word address with practical context instead of sending it without explanation.

For everyday city navigation, I would keep a conventional maps app close at hand. It remains the better choice when I need a route, transport options, or a familiar search experience. what3words is more specialized, and that specialization is both its advantage and its limitation.

After being available since June 11, 2013, the app has had time to establish a clear identity rather than chasing every mapping feature. Developed by what3words, it focuses on a simple question: how can I identify the exact place I mean? My answer is that it does this convincingly, as long as I understand what it is giving me and what I still need from another navigation tool.

My final advice is simple: install it if your destinations are often hard to describe, and treat it as a precision layer for your existing travel habits. If every destination already has an obvious address and you mainly need turn-by-turn guidance, the usual alternative will probably feel faster. If your problem is the last, easily confused point of arrival, this app can be the small addition that prevents a surprisingly large amount of confusion.
