Helplin is a new app that connects people looking for help with those who can provide expertise, using Twilio's API to preserve anonymity. The app was created by Anil Varanasi, who wanted to solve the problem of finding reliable one-on-one help online. With Helplin, users can choose whether to receive or give help, and are connected via a phone call while their numbers remain anonymous. The app has gained traction, with several hundred calls made on its first day, and Anil is now working on adding features such as browser connectivity and charging per call. Twilio's API was instrumental in making the project possible, and the developer community is excited to see what other apps will be built using this technology.
