QUEERSTER is a forthcoming iPhone app from Tentonix GmbH designed to help LGBTQ+ people discover nightlife and community resources in their city. Its listings bring together parties, bars, clubs, saunas and support services, with information on what is happening that evening and which venues are currently open. Users can browse weekly bar events, club nights and festivals, check opening hours, see distances and walking routes, and save events to their calendar with a reminder.

A map and filters help people find places and scene districts that suit their interests, including options related to gender, trans-friendliness, drag and dancing. The app is planned to launch in 12 German cities, with around 2,000 venues and community locations, and more cities to follow. QUEERSTER is being developed with privacy in mind: it requires no account and uses no tracking or advertising profiles.

Location-based distance and city searches are handled on the iPhone, while saved places and events remain on the device. Users can also report missing events or incorrect venue details for review
