Wingle is a mobile application that enables passengers to communicate with each other during flights without needing an internet connection, utilizing Wi-Fi and Bluetooth. The app allows users to send messages and book airport lounge services, and it was launched in Europe in July 2024, with a global rollout planned for January 2025. It has attracted over 20,000 active users, primarily from Europe. Users create profiles that include personal information and a personality diagram, and conversations are temporary, disappearing after the flight. Wingle generates revenue through commissions from booking services, and its reception has been mixed, with some users appreciating the opportunity for social interaction, while others express concerns about privacy and potential misuse.
