Looking for Volunteers to Build Covid19 App

I'm looking for volunteers to help build a COVID19 App. Any help would be awesome including, legal, design, project management, engineering, systems and funding. Version 1 (web app): 1. Sign up with email and invite friends via email. 2. Each day, poll users (through email) for symptoms: - ask people to take poll: - Do they have a fever? - Experiencing shortness of breath? - Do they have a cough? - Other flu like symptoms 3. If they have any of those symptoms email their friends and provide Government recommended advice 4. Ideally in the future, connect the user with a test V2 native app: 1. Allow businesses to print out a unique barcode 2. Users would scan those barcodes when they enter a place 3. If a person reports COVID symptoms who visited the business, email the business, and others who visited the business after that person
