Been using this calculator through many years & 3 different phones now. Easy to understand, intuitive to use and handles everything I throw at it. Starts up fast enough to be friction free for day-to-day use yet capable enough when actual calculations are needed (though my requirements are modest, mostly basic CAS stuff ). It's great to have a single app/interface for everything. EDIT: I recently had an app store related issue and needed customer support. Said support was quick and effective.

Has been great for almost everything I have needed it for. Accurate and precise. Algebra has been a cinch with this. I hope that the designers continue to add more features such as unit conversion and maybe even possibly the ability to draw geometric shapes, assign values to their parts, and then use them for your math problems. Great overall.

I'm very much into calculators. This app was such a shock, to me, due to its powerful simplicity. For example, I just saw a poll on the news and it said, "there's a 59000 difference with 3% of the vote in" In this app I first typed 'x-y=59000' It beautifully entered that equation. Then, I clicked the "add equation button" The workspace is like paper. It simply adds a new area to make a new equation. Then I typed '.03(x+y)=59000' and it automatically uses the above to solve. I love it

I am a retired engineer who tutors high school students in math. This graphing calculator is very powerful and is a pleasure to use -- especially compared to the antique TI-8x machines that are still in so many classrooms. My only complaint is that it isn't available for Chrome OS. The bigger screen would be wonderful, and Chromebooks are common in high schools.

I'm an engineer and I love this calculator. It could use a button for POL/RECT next to the RAD/DEG button on the toolbar. EDIT: The only thing I don't like is the recent addition of the circular blue + button in the calculation/display view area (for adding a new entry), it obscures calculations and graphs in display area... is there a way to remove it or make it hideable?
