What3words uses a satellite map for users to make it easy to use and understand. It is not a Google Maps rival as it will not help you with navigation to any particular address.
You're not allowed to know what word lists W3W use. They take a paternalistic attitude to creating their lists - they know best. You cannot propose changes. Anecdotally, their non-English word lists are confusing even for native speakers.
what3words is free for anyone to use via our app and online map. We make money by charging some businesses that benefit commercially from using our products.
Does the app work without signal? Without phone signal, the app functions the same as when you have no data connection: you can view the location of any what3words address you enter. You can also navigate to it using compass mode. To share a what3words address over the phone or in a text message you need phone signal.
