What Three Words App – Free Download and Usage Guide

The what3words app transforms the way people share and locate places on Earth. Instead of relying on traditional street addresses or complex coordinate systems, this free mobile application assigns a unique three-word combination to every 3-meter square across the globe, enabling pinpoint precision for navigation, deliveries, and emergency responses.

Available for both Android and iPhone devices, the app operates without requiring cellular data or internet connectivity. Users can simply download it from their respective app stores, grant location permissions, and immediately access their current three-word address. The technology has gained significant traction in the United Kingdom, where delivery companies, emergency services, and hospitality businesses increasingly incorporate these addresses into their booking confirmations and contact pages.

This guide covers everything from the initial download process to advanced features like offline compass navigation, helping readers understand how what3words works across different platforms and why it has become a valuable tool for precise location sharing.

What is the what3words app and how to download it for free?

The what3words app serves as a geocoding system that divides the entire planet into 3-meter squares, with each square assigned a unique combination of three words. Every 3 metre square of the world has been given a unique combination of three words, according to information published on the official what3words website. This approach simplifies location sharing compared to traditional latitude and longitude coordinates, which are prone to transcription errors and require additional applications for proper conversion.

Quick facts overview

What3words app for Android

Android users can download the what3words app free of charge from the Google Play Store. The application requires Android version 7.1 or newer to operate properly, and minimum device requirements may exclude older smartphones from running the software. Once installed, the app supports Wear OS for smartwatches, allowing users to check their three-word address directly from their wrist.

Users with Huawei devices that do not have access to Google Play should use the online map available at what3words.com instead, as the Google Play Store version cannot be installed through alternative means on affected devices.

Finding your three-word address on Android

After opening the app, users should allow location services to access their current position. The interface displays a blue dot indicating the current location, which should be allowed to stabilize before reading the three-word address. For areas where the GPS signal is weak, users can search for street names and zoom in to identify the exact 3-meter square, or manually enter the three words to pinpoint a location.

Switching to satellite view provides additional visual confirmation of the precise location being identified. Users can also adjust the language settings by tapping the menu, selecting Language, and choosing from available options before restarting the application on Android devices.

Android-specific tools and integrations

The Android version includes an AutoSuggest feature that assists with word entry as users type, reducing input errors. A Scan camera tool enables quick capture of three-word addresses from printed materials or screens. The app displays coordinates alongside the what3words address, providing flexibility for users who need both formats. Navigation integrates seamlessly with Google Maps, allowing users to send their destination directly to the mapping application.

What3words app for iPhone

The what3words app for iPhone is available as a free download from the Apple App Store under the identifier id657878530. The application requires iOS 14 or later to function, ensuring compatibility with most modern iPhones and iPads. Like its Android counterpart, the iOS version includes in-app purchases, with a 7-day Pro trial available for users who want to explore enhanced features before committing to an annual subscription plan.

iPhone users benefit from the same offline functionality as Android users, relying entirely on GPS signals for location determination. The app performs best outdoors with a clear view of the sky, though it continues to function in areas where traditional address information may be incomplete or non-existent.

Sharing locations from the iPhone app

The sharing functionality allows users to send their three-word address directly through messaging applications, email, or social platforms. This proves particularly useful for coordinating meetups, directing delivery drivers to specific entrances, or providing emergency responders with precise locations in remote areas. Users can also save favourite locations and organize them into custom lists for easy access during future visits.

The capability to add what3words addresses to photos enables users to document locations automatically when taking pictures, creating a geographical record that can be referenced later without relying on memory or external notes. The Compass feature, which operates offline, displays an arrow pointing toward the selected destination, helping users navigate to their precise target even without cellular connectivity.

Navigation integration on iOS

Integration with Apple Maps and other navigation services allows users to transfer their what3words location directly into turn-by-turn directions. When a user selects a three-word address within the app, options appear to open the location in compatible mapping applications, streamlining the transition from identification to navigation. The same AutoSuggest and camera scanning tools available on Android function identically on iOS devices.

What is my three word location?

Finding your personal three-word location requires nothing more than opening the what3words app and waiting for the GPS signal to establish your current position. The app displays the three words corresponding to your exact location on the screen, updated in real-time as you move. This address remains constant for each 3-meter square, meaning returning to the same spot will always reveal the same three words.

Users who prefer not to rely on GPS can enter any address or location name into the search function to discover the corresponding three-word combination. Alternatively, typing the three words directly into the search bar reveals the associated location on the map, useful for finding places shared by others or verifying addresses received through messaging.

Using three-word addresses for meetups and deliveries

When arranging to meet someone at a specific location, sharing the three-word address eliminates confusion about entry points, parking areas, or pickup spots. Unlike traditional addresses that might describe a building generically, what3words can pinpoint the exact side of a building, the entrance to a park, or a delivery loading zone. This level of specificity reduces missed deliveries and failed meetups caused by ambiguous directions.

Delivery companies increasingly incorporate what3words into their confirmation emails and tracking systems. Customers can add their three-word address during checkout to ensure drivers locate the precise delivery point, particularly valuable in large properties, rural areas, or complex urban environments where street addresses alone prove insufficient.

Saving and organising favourite locations

The app allows users to save locations under custom names and organize them into lists. A user might create separate collections for holiday destinations, work sites, and regular appointments. Each saved location stores its three-word address along with any notes the user wishes to add, creating a personal library of precisely identified places accessible whenever needed.

Photographers, field researchers, and outdoor enthusiasts particularly benefit from this organizational capability, as it enables them to return to exact observation points or scenic locations without relying on memory or manual coordinates. The ability to attach addresses to photos further supports this documentation process.

What3words website and UK access

The official website at what3words.com serves as the central hub for information about the platform, including downloadable apps, an online map compatible with Chrome and Safari on mobile browsers, and support resources. Users without access to app stores can generate and share three-word addresses directly through the web interface, making the service accessible from any device with internet connectivity.

In the United Kingdom, what3words has achieved particularly strong adoption across multiple sectors. Emergency and breakdown services, including those operated by the AA, have integrated what3words into their response protocols, with approximately 85% of UK services now accepting three-word addresses during call handling. This integration proves especially valuable when callers cannot describe their location using traditional landmarks or street addresses.

UK business and hospitality integration

Hotels, restaurants, and retail businesses throughout the UK increasingly display their what3words addresses on contact pages, booking confirmations, and welcome materials. Guests can use these addresses to locate entrances, parking facilities, and check-in points with greater accuracy than conventional directions would allow. Some properties include multiple what3words addresses for different areas of their premises.

Delivery companies operating in the UK have similarly embraced the system, incorporating three-word addresses into their routing and confirmation systems. Customers receive their unique address upon order placement, enabling couriers to navigate directly to the specified 3-meter square without searching for house numbers or building entrances.

History and development of what3words

Search results provide limited information regarding the detailed company history and specific milestones in what3words development. The company, registered as WHAT3WORDS LIMITED, originated as a geocoding system designed to address the limitations of traditional addressing infrastructure, particularly in areas lacking standardized street naming conventions.

The core innovation involves a proprietary algorithm that assigns three-word combinations to 3-meter squares across the globe, with each address engineered to be memorable, distinguishable, and resistant to confusion between similar-looking word sequences. This algorithmic approach ensures that no two neighbouring squares share similar three-word addresses, minimizing the risk of miscommunication.

The app has remained available on both Google Play and the Apple App Store continuously, with regular updates improving functionality and expanding language support. Official tutorials and step-by-step guides are published at what3words.com/how-to-use-the-what3words-app, providing users with foundational knowledge for getting started with the platform.

1. The what3words geocoding system divides the world into 3-meter squares using proprietary word assignment algorithms
2. Mobile applications launched for Android and iOS, enabling users to discover and share three-word addresses
3. Expansion into emergency services integration, beginning with UK breakdown and assistance providers
4. Adoption by over 4,800 US 9-1-1 call centres as a location verification tool
5. Ongoing development of language support, expanding the service to 50 to 60 languages
6. Continued availability through official app stores and the web-based map interface

What is confirmed and what remains unclear about what3words

Why what3words matters for location sharing

Traditional addressing systems were designed around settlement patterns and property boundaries, not the need for precise location identification. Street names and house numbers work adequately in urban areas with established infrastructure, but become unreliable or entirely absent in rural regions, newly developed areas, and outdoor recreational zones. The what3words system addresses this gap by providing consistent, grid-based addressing that functions anywhere on the planet.

The simplicity of three-word communication proves particularly valuable in emergency situations, where stress and unfamiliar surroundings can impair a caller’s ability to describe their location using landmarks or cross streets. Emergency dispatchers receiving a three-word address can immediately plot the caller’s position and dispatch responders to the exact 3-meter square, eliminating the ambiguity that traditional addresses sometimes create.

For e-commerce and logistics, what3words addresses enable more efficient delivery operations by directing drivers to precise entry points rather than approximate locations. The system reduces failed delivery attempts, customer complaints, and operational costs associated with locating hard-to-find addresses. Businesses that adopt what3words can provide customers with exact directions that work reliably regardless of language barriers or unfamiliarity with local landmarks.

The platform continues to expand its reach through partnerships with navigation providers, emergency services, and hospitality businesses. Users can explore how this addressing system applies to their specific needs by downloading the application and experimenting with location identification in their area.
