Every place worth remembering, kept in one book. LocationBook turns any spot on the map into something you can save, find again, and hand to someone else. Drop a pin at a trailhead, a friend's flat, a parking space, a viewpoint β and keep its exact coordinates, its address, and a way to share it. SAVE ANY PLACE Double-tap the map, tap a point of interest, or search by name. Every saved place keeps its exact latitude and longitude alongside a readable address you can copy with one tap. SHARE THE WAY Generate a QR code that opens the spot in Maps on any phone β no app required at the other end. Or send a route link through chat, mail, or notes. KNOW WHEN YOU ARRIVE Mark a region around any saved place and get a notification when you enter or leave it. Set the radius, choose whether it fires on arrival or departure, and add a note to remind yourself why. SAVE A FRIEND'S PLACE Link a contact to any location, and pull their address straight in from your address book. Find their place again by their name. YOUR PLACES, ORGANISED Saved locations live in an alphabetical list with an A-Z index down the side β the same way your contacts work. Search by name, by address, or by coordinates. BUILT FOR THE MAP Choose standard, hybrid, or satellite. Switch between kilometres and miles. A cartographic palette designed for both light and dark mode, so it reads at noon and at midnight.
