THE KEY is your safer-raving companion by SCHLUESSELKINDER. It helps you and your crew look after each other, before, during and after the night. No tabs, no hunting: the app walks you through your night, station by station. THE NIGHT BEGINS IN THE CALENDAR Discover club nights, raves and festivals in Cologne right inside the app and take your night with a single tap. No retyping. From there the app leads: Ticket, Crew, Prepare, Live, Way home, After. TICKET · WALLET The ticket button takes you straight to the seller, the purchase happens in the browser. Then put your ticket into your wallet: as a photo, screenshot or PDF. Everything stays on your device. At the door: one tap, fullscreen, full brightness. Honestly put: your ticket lives with the seller, THE KEY keeps the copy and reminds you on the day of the event. CREW Start a crew or join by link/code, shareable via WhatsApp, Telegram or message. The invite carries the night with it: whoever joins sees the event, venue and meet point. No one goes alone. LIVE A calm status pulse sums up your load from movement, dance time, heat and breaks. Gentle nudges: drink water, take a break. Live step counter. Crew board: who is dancing, who is on a break, who is already home. Help button: one tap and your whole crew sees the alert until someone gives the all-clear. Check in when you arrive, check out when you leave. WAY HOME + AFTER Getting home is part of the night: your crew sees who has arrived safely. Then Wrapped, your night in numbers, and the 3-day recovery. Finally the night and its ticket move into your wallet archive. UNDERGROUND An optional, invite-only area for collective events. Pre-moderated, with report and hide actions. Access only through an invite code from the scene, with no exact addresses in the app. PRIVATE No login, no tracking, no ads. Anonymous device ID. Sensitive data stays encrypted on your device. IMPORTANT THE KEY is not a medical app and is no substitute for professional help. In an emergency call your local emergency number. The app does not measure body or room temperature: outdoors it uses Open-Meteo weather data, indoors it estimates floor heat from movement and your input. Step data comes from the iPhone's motion sensors. Adults only. by SCHLUESSELKINDER · Cologne ## Version history (last 5 releases) ### 0.4.2 — 2026-07-10 The calendar now shows every night day by day: weekend always Fri-Sun, all events in order, plus a date-range filter. Curator picks are marked. Polish across the whole app: clearer navigation, calmer typography, tactile feedback. ### 0.4.1 — 2026-07-09 Fixed back navigation, you can leave a night any time. Events are detected from your ticket (Wallet, photo, PDF). New: plan several nights ahead, each with its own crew. Removed the genre picker from settings. ### 0.4.0 — 2026-07-07 The wallet is complete: besides photo, screenshot and PDF, THE KEY now reads wallet passes (.pkpass) and renders the actual barcode at the door, fullscreen, full brightness. Plus: the wallet archive as a ticket stack on the calendar, a recovery card after a finished night, solo mode in the crew station and a visibly connected station path. ### 0.2.0 — 2026-07-04 The night now begins in the calendar: browse events inside THE KEY and plan one with a single tap. New: invites carry the night with them (whoever joins sees the event and meetpoint), a reminder on the day of your event, an invite-only, pre-moderated Underground section, and ticket buttons that lead straight to the seller. ### 0.1.1 — 2026-06-12 Plan handover from the website: raves from antisobersoberclub.de/kalender now open directly in THE KEY with name, venue and date prefilled. Plus small fixes. ## More apps by Thomas Frerich - [Gruvi - Music for Kids](https://appshunter.io/ios/app/gruvi-music-for-kids/id6782685269) All apps by Thomas Frerich: https://appshunter.io/developer/1869405179 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
