Not User Friendly – Rocket Math Addition Review

Seriously! Add an option to change the time length. I have 5 children working with this app on two devices (because you are only allowed three on each device?!?) and I couldn't figure out why they all cringed when I would have them practice. It's the three second aspect that can't be changed. I finally just told them to tell me the answer and I would type it in and I couldn't even beat that darn timer. No wonder. Your design is flawed and you should really think about listening to your users.
