Rockets is a personal launch-day companion for spaceflight fans who want to know what is worth watching, what changed, and what to do next. Today highlights the next relevant mission and source freshness. Explore keeps the 3D globe, search, Mission Planner, and Launch Pulse. My Missions saves a complete local journey, while Launch Room combines the countdown, status, source details, change history, Calendar, Live Activity, and alert controls. Mission Control is the existing optional EUR 4.99 one-time purchase. It unlocks unlimited watched missions and advanced enthusiast tools forever. There is no subscription, trial, recurring billing, account, or Rockets-operated backend. Existing Mission Control buyers receive the Rockets 2 paid capabilities automatically after StoreKit restoration. Explore launch sites on a 3D globe, search pads and missions, compare recent and upcoming launches, and use Mission Planner to filter missions by provider, orbit, status, timing, and weather or hold concerns. Add selected launch windows to Calendar and start a Live Activity for upcoming missions. Rockets uses Launch Library 2 for launch schedules and launch pad data. If launch-site data is temporarily unavailable, the app may use OpenStreetMap Overpass as a fallback for public launch-site map data.
