Literably has also made some improvements--there are now pictures that go with the story and comprehension questions that follow. Yet to see the results, the teacher will have to use the original website. The app is for students and the website is for the teacher because that is where you can see the student's reading accuracy and speed and the reading comprehension question scores. That is the part that has not changed.
If you haven't used Literably before, now is the time to try it. I encourage all elementary and middle school teachers to try it. Our students are spectacular readers, so this would be one way for them to see their improvement and share that with parents. Check it out for yourself!
