What I like about this post from http://www.twoguysandsomeipads.com is the screen shots and descriptions from the program....
Remind 101 is an tool that allows you to text your students or stay in touch with parents in a secure and safe way. Teachers never see student or parent phone numbers, and they will never see the teacher's phone number. Educators can send messages using the mobile app on Android and iOS devices, as well as www.remind101.com.
This tool is great for friendly reminders about field trips, homework, plays, events, or a kind motivational message. Remind 101 has recently redesigned their iOS app with great new features and a teacher resource page to help with any questions.
These pictures are of the newly redesigned Remind 101 iOS app.
This is def. something I want to try using.....
