Ratings and Reviews
Seriously a great app
It's addicting and at the same time teaches me both tricks and novel ways of thinking with math. I'm around numbers all the time at work and school, so the challenges and secrets of math this app reveals is priceless to me. Yes, I'm a huge fan and I play this on the train and before I go to sleep at night.
Safe?
I bought this app years ago but I quickly deleted it because I couldn’t figure it out. I was just thinking about installing it again just in case there’s a chance I would do better. However, before I install any old apps, I always try to visit the developer’s website first. This one doesn’t seem to be safe because I don’t see it being locked. I’m now having second thoughts. Is there anyone that can help? If not, I’ll just let this app stay where it is and hope that some one notices.
Love this app
One ask: I wish the "play" selected categories were persistent. I.e. The ones you selected the last time you played are selected them next time you played.
Update: Reiterating this one year later. Still love the app, but I would use it regularly if I could “set” which Play categories I wanted and they would stay set every time I opened the app
