Automate web toggle switch on/off via a timer

Project: Create a web app or iOS app (whichever is easier) to automate turning on and off the Vonage "do not disturb" toggle switch. Requirements: - The app would allow the user to enter and save the Vonage user ID and password (pic1) - The app would allow the user to enter the start time and end time. (pic2) - The user can click on or off for each day for that start and end time. - The user can set one on/off time. - Once the user is done, clicking a save button will set the app to log in and toggle the switch (turn on and turn off the do not disturb feature) according to the set times. - If nothing is changed, the app will continue to turn on and off the do not disturb each day. [login to view URL] Error checking: 1. Verify the app has the correct user ID and password. I am open to the UX / screen layout if you find a more efficient way to have the user enter the on/off start/end information.
