Build Version 2.0 of Safety App

We need the following features for the 2.0 version of the app: * Ability to pre-set events throughout the day: Users will be reminded each morning to set when they want to be watched over throughout their day. They can A) Copy from yesterday B) Sync with Google Calendar or, C) Enter manually. * The app should watch over them during the predetermined sessions. E.g. if going to work is between 8.30AM - 9.30AM -- at 8.30AM Watch Over Me should be able to start tracking their location every minute until 9.30 AM when the app sends out an alarm/push notification asking if the user is safe. If the user does not respond, the app sends out an emergency alert to the user's emergency contacts. * Additional sharing capability -- ability to invite friends to download the app via Facebook Messenger / Post to Facebook / Twitter etc. * Emergency notifications via Facebook Messenger (in addition to the current SMS, and email) * Insert 4-digit passcode to confirm your safety (can be turned on/off in settings)
