In order to make users aware of upcoming Challenges and then to help keep them engaged during the Challenge, the app has several notifications that are automatically sent without any action required of the Administrator. The Administrator can certainly create and send additional notifications, but as you plan, be aware that the following will be sent automatically. The timing will vary, depending on the duration of your Challenge, but we'll use a 10 day Challenge for example purposes below:
As soon as Challenge is ready - Challenge Available. Join now!
2 Days before Start (if Challenge is available) - Challenge Starting Soon. Join now!
Day 1 - Challenge has begun! Start logging Actions!
Day 5 - It's halftime in Challenge. Are you going to be the champ?
Day 8 - Challenge Almost Over. Last chance to Log Actions!
Day 10 - Challenge Ended. See who won.
