Set a timer with one tap. If you don't cancel it in time, your chosen friends automatically receive an urgent SOS alert along with your live location, map feature lets you track the real-time location of friends who have their timer switched on. The app also features a dual database of maniacs: famous historical serial killers for awareness and education, plus currently wanted dangerous individuals near you. On top of that, an AI detective is ready to recommend books, podcasts, and movies, or dive deeper into the stories of notorious maniacs whenever you want to learn more. In the free version, you can select only one friend for SOS alerts, ask the AI just one question, and view only three popular maniacs — the wanted section is locked. The paid subscription removes all these limits. Subscription is auto-renewable and can be turned off anytime in your App Store settings.
