Attack Alarm is a personal safety app designed to help you react quickly when you feel unsafe. At its core is a fast one-tap alarm that can play a loud siren to attract attention nearby, but the app also gives you extra tools for situations where you need a quieter or more discreet response. Choose between Loud Mode for an immediate alarm, or Silent Mode to access safety tools without sounding a siren. You can also customise how the alert behaves with different alarm tones, screen pulse, torch flash, brightness boost, and optional spoken help phrases. Attack Alarm also helps you prepare for the next step. Choose a trusted contact from your contacts, quickly open Messages with a pre-filled SOS message, call your trusted contact, or call emergency services for your region. If location access is available, the app can include your current Apple Maps location link in the message. For extra reassurance, Attack Alarm can help you find nearby places such as police stations, hospitals and pharmacies, or open a fake call screen to help you leave an uncomfortable situation more naturally. The app also includes an on-device incident timeline, so you can save notes, keep a record of events, and export the timeline afterwards if needed.

When you set off an alarm, the app can now record everything that’s going on for your safety. When the alarm is stopped, the recording is saved in the app. (*While the alarm is sounding loudly, you may not get usable audio. If the alarm is set to silent, you will get full audio recording fidelity, unfortunately there is no way around this on iOS devices.) Attack Alarm is designed to help you feel more prepared, more visible, and more in control when you need support quickly. Stay safe.
