What Plane? was built to answer one question—fast: what’s that aircraft overhead? Everything is designed for instant glanceability, so you can get the answer without “using an app”. Add the widget to your Home Screen and tap to refresh. Tap the custom aircraft icon to jump straight into the live map. Inside the app, controls stay just as simple. Want different units? Tap any stat (altitude, speed, distance) to cycle through options. The default view lets you explore nearby air traffic, and with a single tap on any aircraft—or the menu button—you can browse rich details for every plane within 30 nautical miles. To keep the interface minimal while adding real information density, What Plane? uses the Compass Ring: the panel border doubles as a bearing indicator, showing the aircraft’s direction relative to you at a glance. And when an aircraft is overhead, the widget brings it to life with airline-specific liveries and aircraft models—so your Home Screen matches what’s in the sky. WHATPLANE PRO (OPTIONAL SUBSCRIPTION) Choose the aircraft you want to spot and get an alert when a match is nearby. Chat with Lookout to ask about aircraft recorded in your area while you were away, and prioritise your matches in Dynamic Island. Pro is a monthly auto-renewable subscription, purchased separately in the app, with a one-week free trial for eligible new subscribers. After the trial, the subscription renews at the displayed monthly price unless cancelled. The local price is shown before purchase. Payment is charged to your Apple Account. Your subscription renews automatically unless cancelled at least 24 hours before the current period ends. Manage or cancel in your App Store account settings.
