What's a good iOS app for easily sharing precise locations, even without street addresses?

what3words: Navigation & Maps is a fantastic solution when you need to pinpoint a location more accurately than a street address allows. It has divided the entire world into a grid of 3-meter squares, and each square has a unique three-word address. This is incredibly useful for meeting up in parks, at festivals, or in rural areas where traditional addresses are vague or nonexistent. Instead of trying to describe 'near the big tree by the pond,' you can simply share the three-word address of that exact spot. The app is easy to use: just open it, find the location on the map, and get its corresponding three-word address. You can then share this address with friends, family, or even emergency services, ensuring they know precisely where to find you. It's a game-changer for precise location sharing.
