InFlight Simulator turns any journey in the world into an immersive passenger experience. Pick a route, take a window seat, and watch the full flight unfold from takeoff to landing with a moving map, changing views, and the calm feeling of being in the air. The app went viral and has already welcomed tens of thousands of players, with the audience continuing to grow through word of mouth and organic discovery. That response revealed a much larger market for relaxing, immersive travel experiences that combine simulation, exploration, and digital escapism. We are ready to build on that momentum and bring new experiences to this growing audience. Our goal is to keep the original game free for the community that made it successful while creating entirely new ways for people to explore, travel, and escape through their screens. We are looking for a technical co-founder who wants to help shape what comes next for a product people already love.
