Needing a free translation app to help communicate with students that speak different languages? Say Hi is a free and easy to use app for the phone. According to the website, the teacher can "Have a conversation in two languages and easily understand each other," 

The app is free from the Apple Store and according to the website it is "quick, easy, and uncluttered so you can converse without distractions. There are 90 languages and dialects."  I have used it several times in my classroom to help communicate to my students that speak little English. I open the app, say what I want to say into my phone, and the app translates it aloud to my students. It has become very useful with directions for assignments, homework and checking for understanding.
