Remind is a communication tool that allows teachers to connect instantly with students and parents—without revealing the phone numbers of either party. The app operates like a private text-messaging service: After a simple, fast and free sign-up, teachers can send one-way messages to an entire class or an individual subscriber. Students and parents choose whether they’d like to see the messages as texts, e-mails or smartphone notifications. The app stores message history and includes a time stamp for each message (like an iPhone’s Read Receipts feature). Send competition team schedule changes, weather-related updates about closing the studio or photos of what hair and makeup should look like. With Remind, you can attach photos, documents, PDFs, presentations and even recorded voice messages. If you need a response from your students, you can opt to begin a two-way chat with a specific subscriber.
