Remind 101 is a free app that is awesome for teachers, coaches, or any group you need to send reminders to. The great thing about the app is that when you create an account it gives you directions to give your students or whoever to sign up and they cannont text you back. This app is useful on your phone because if you all of sudden remember that you forgot to remind the kids of something, you can send out a group message and those who signed up and are apart of your group recieve the message. It is good for when you do not want to look up a bunch of numbers to add to a text and they cannont respond to the message. It is geared toward quick reminders and it works so well. So go create an account for the new school year and get your parents to sign up!
