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. Features • One-tap personal safety alarm • Loud siren mode for immediate attention • Silent mode for discreet access to safety tools • Two alarm tones: Classic and Pulse • Optional spoken help alert • Spoken alert languages: English, Spanish, French, and German • Screen pulse effect for extra visibility • Torch flash burst • Temporary screen brightness boost • Trusted contact selection from your contacts • Quick SOS message preparation • Quick call to trusted contact • Emergency call options for your region • Nearby help finder for police, hospital, and pharmacy locations • Fake call screen for uncomfortable situations • Incident timeline with notes and export sharing • Designed for fast access and simple use • Pick your own icon colour • Added a new feature: Record Sessions. 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.

Read full description

TreeRings helps you explore the hidden history of trees. By analyzing a photo of a tree’s cross-section, the app estimates the tree’s age by counting its growth rings. Beyond age, TreeRings also gives an indication of how favorable each year was. Wider rings may reflect years with good growing conditions — for example, a rainy summer — while narrower rings can hint at harsher times. These are always approximations, but they can provide fascinating insights when you’re on a hike, studying forestry, or working as a forest ranger. By comparing results from multiple trees in a region, TreeRings can even suggest patterns about the local climate over time. Simple to use: just point to the center of the cross-section and let TreeRings do the rest
