Twilio’s RubyGem made integrating the app with Twilio very easy, allowing Ross to send an SMS in just two lines of code. The app was built using Ruby on Rails and Bootstrap, deploying on Heroku, and quickly became a hit, with over 750 developers signing up within 24 hours. Ross attributes his success to Twilio's ease of use and the fact that it allowed him to focus on building the service without worrying about complex technical issues. The app was well-received by users, who appreciated its instant notifications via SMS, and Ross has expressed gratitude for Twilio's support and engagement with young developers like himself.
