PhoneFlare is an Ionic-based mobile app available on iOS and Android designed to enhance personal safety by allowing users to trigger alarms in unsafe situations through actions like pulling an accessory from the headphone port or pressing a button. Developed by Chris Jarvis, the app supports features such as setting check-in times, sending location-based alerts, and contacting campus safety, with advanced functionalities like audio recording and UDID logging. It is particularly aimed at preventing sexual assaults on campuses but also serves broader demographics like children and the elderly. The development leveraged Ionic and AngularJS for a seamless cross-platform experience, benefiting from the community's support and the ease of using Cordova plugins. Jarvis highlights the advantages of Ionic, such as rapid prototyping without mockup software, intuitive design changes, and live debugging capabilities, all of which contributed to a positive development journey.
