Twilio and Heroku were used to create a simple voice reminder system for tracking litter box cleanliness in an effort to improve cat care and hygiene. The system uses a REST API to interact with phone calls, allowing the user to initiate actions such as making a call to remind them of their tasks. A custom XML format is used to control phone conversations during the call, enabling the user to respond to prompts and receive reminders. The system was built using Heroku for deployment and Twilio for its voice capabilities, with a Rakefile task initiated by the Heroku scheduler to run daily. This project showcases how accessible APIs can be used to solve everyday problems.
