This app has issues when I first downloaded, but after I hard restarted my phone it has worked beautifully. I have noticed that people are complaining that there are only 4 catagories to choose from but after you master those four you get four more catagories so keep going! I am currently on my 9th category (every time you complete 4 it gives you a new set of 4)and I am wondering how many it has! I love, love, love this app and I cant believe it is free. My 6 yr old loves it too! The only things I wish could be changed are: A sign in area so that when more than one person is playing it would start where you left off and/or a menu area so that I could go back to any catagory that I had already completed. Keep up the good work 321speak.
