The app often stops responding especially when i click the solve button and review the problems given by community. Also it doesn't save any of the questions like it's supposed to.Please do something ASAP to fix this. Otherwise the app's perfect.
the sample problems are challenging, but if you don't get the correct answer the first time. there is zero ability to learn. also the $6 monthly charge is steep.
Wonderful app to keep oneself sharp and observant.Helps me brush up on a lot of fundamental concepts and also helps teach new concepts in a fun and entertaining way.Overall their app is fantastic, even if you choose not to pay for the premium version.Though I recommend getting one to get full benifit of the app.
Had an issue with images not showing up properly, but thanks to the developer who responded to my feedback, the issue has been resolved
For astronomers like me, it is very helpful. But some things are a little complicated :/
I love your app. I'm not in school because I can't afford it yet but your apps keeps me from failing behind .
