Ratings and reviews

I've used this app for a long time, in math courses and as a math tutor. I decided to buy the full version and ran into a problem for which I wrote a really bad review the first time, but I deleted it because it didn't make justice to the app. I've tried other apps and none are as elegant as this one and functionwise they almost give the same things, but I prefer how this one is organized and displayed and the array of options given.

Wouldve been 5stars...but I've used this app for awhile now, it has been a great tool and aide in many projects. Enough so that I paid for the pro version to remove ads and unlock all formula options. Coincidentally when I opened the app today to use for use with determining a legal description of an easement. It requested that I buy the pro version to unlock features and remove ads. At some point between todays use and my previous use, it downgraded me. I'm not paying twice for this app.

the problem is that for the samsung users (like me and my other classmates) are having a hard time using it cause the equation is really small.. and it's hard to read.. but all in all it's really helpful for us~
