Invaders Finder helps you spot and track Invaders around the world, like an urban treasure hunt on the map. MAP • View invaders on an interactive map, with clustering when you zoom out. • Quickly spot statuses thanks to colors (active, damaged, destroyed). • Adjust the clustering detail level and map theme to match your style. FLASH TOUR • Build a walking route in seconds: by duration, distance or number of Invaders, as a loop or from one point to another. • Compare several itineraries, pin the Invaders you really want to see, then set off. • Follow the real walking route step by step, log your flashes as you go, and share your route when you finish. • Included in the Pro subscription, with free trials to try it out. LIST & CITIES • Browse the list or the Cities tab: progress, flashable invaders, points, and sorting to decide where to hunt next. FLASHES • Mark an invader as flashed right from the map. • Filter the display to focus on what's left to find. DETAIL VIEW • Open an invader's page to act right away: mark as flashed, direct link to Apple Maps or Google Maps. • Quick access to Invader Spotter and Instagram when you want to dig deeper or share. ACCOUNT & SYNC • Sign in (email, Apple, or Google) to save your flashes in the cloud and never lose anything when switching devices. NOTIFICATIONS • Get alerted when a new Invader is added or an Invader's status changes. LANGUAGES • French, English, Spanish, German, Italian and Japanese, with a language picker in the settings.
