This app started out great for the first weeks spelling test! My son that has struggled with spelling got his first 100% ever. However, this week's spelling test has given me nothing but problems. The games kick my boys out of the app, forcing them to start over, which has really frustrated them. Also even though they spell some of the words correctly, it will mark them incorrect. That is also extremely frustrating to two 9 year old boys. I am going to get a refund.
