Cilia is a safety alarm application designed for iPhone users, focusing on personal security and emergency response. It offers a range of features to prevent assaults and aid in evidence collection during crimes. Users can utilize the app for free as a 'Rescuer' or subscribe for full access to alarm functionalities. The app allows users to send alerts to their emergency contacts with just a tap, while also enabling a discreet alarm option for sensitive situations.

When activated, the alarm triggers a loud sound or silent alert, depending on user preference, and initiates automatic audio recording for potential evidence. Emergency contacts receive notifications and can track the user's live location, provided they authenticate with BankID. Cilia emphasizes the importance of safety and offers a two-week free trial of its subscription service, which unlocks additional features and allows unlimited emergency contacts.
