I love the scheduling aspect of this app. I teach fifth grade and have a family of five. Sometimes when I am working it is very late at night or early in the morning and I dont want to forget to text a brainstorm lesson plan to my colleagues, or message to my principal or parents. One thing that needs to change in my opinion, and I think it will due to the demand, is the limitation of characters. Teachers have A LOT to say and explain. It is frustrating when we are cut off in the middle of an explanation or when giving directions. I would send through email, but I know my last principal had 2,000 emails on his phone he still had to go through and always told us texting was best to reach him. This is the case with many of my colleagues too. Teachers get a lot of junk emails/coupons we must sort through. Delayd is an app on my iPhone I do using frequently so I give it 3 stars with a "Needs Improvement" on the limitation of characters.
