Danielle Leong, a front-end web developer at Twilio, created a life-saving voice reminder system for her 92-year-old grandmother using the Twilio platform. The system calls her grandmother's phone every day at 10am with an mp3 recording of Danielle's voice reminding her to take her medication. On Sundays, it plays a different message. The system has been running successfully for nearly two years and has become a highlight of her grandmother's mornings. The code is based on the Twilio Call Request demo and uses a PHP app hosted on Heroku with a job scheduler to run daily. Danielle's grandmother is grateful for the reminders, which have helped her stay on track with her medication schedule.
