Wallpapers wont downloaded

The app is okay. Very basic. I would like an option to see my history of days sober. The milestone wallpapers (at least the one and two week ones) will not download and the email for the developer is invalid. iPhone 6s.
Also, the reminders dont work and I would like to receive motivational messages at a specified time.
