1/5No trial?
The app's page shows an option for a 7 day free trial. I'm testing out a few graphing calculators in lieu of buying a physical TI-84. The app installed fine but when it opened, I got the error "product not available"; the free trial is apparently no longer available despite being listed on its page. So I'm unable to perform even the most basic graphing functions. I need it for a math-heavy degree but it's useless if I'm unable to test it--other graphing calculators I've tested haven't been consistent (correct) in their calculations, so being able to test before subscribing for a whopping $30 per year is a must!

1/5Does it even graph?
The icon depicts the application creating a graph, so I did expect it to create a graph at least once. I understand it's got in-app purchases, but if it will graph anything for users who are still trying to assess whether this app will serve their needs before buying anything, I was unable to tell how. Entering an equation for a parabola yielded a constant when I tried entering it at the first prompt and when I clicked the "graph" button I wasn't allowed to enter anything before being confronted with an ad. This app might rock the casbah, but it gave no indication what kind of behavior it would provide to those who chose to risk paying money to see.

4/5I wish the description listed which functions were for the PRO version
Pretty similar to TI-84 CE, but needs to enumerate clearly what features are PRO exclusive and which ones aren’t. For the price of $0 compared to its 150 dollar counterpart, I’d say it’s pretty good. Sadly, haven’t been able to do much statistics on here (regression, test values). It can graph, but it can’t do calculus or find max. It’s also missing an equation solver (but has a quadratic equation solver). Actually now that I think about it it can pretty much only graph and do the same things the built in calculator can. But still a decent value compared to the 150$. Plus since you already carry your phone around, it’s not bad.

3/5Meh
I paid 29 dollars to have this forever. And compared to playing 100$ for a real one that’s a pretty good deal. bUt, I’ve run into some issues with the calculator. Specifically when solving lengthy equations, it never carries the negative through the problem. For example, if I were to put in -3•4 I would get -12, but then I multiply my answer by 8, (-12•8) and it would give me positive 96, rather than -96. This has caused a few issues on some assignments for me but once I figured out what was happening it was pretty easy to continue. I also have a hard time looking at graphs when I graph them. I’ll put my equations into the Y= and it will graph fine, but I can never see the full graph, and because of that I can’t find the intersections and all that. Other than that it works pretty good, I just try to use it for the more basic stuff that my phone’s calculator can’t do.

5/5AMAZING APP
This app is the most amazing thing ever. Other than the fact that it puts you through an ad when you open the app, this is easily the best graphing calculator that’s mostly free. You can’t graph certain things but most everything is free. This is such a great app, and I have so much fun creating my own calcular and deciding all the fun colors. It also has other feature that standard graphic calculators DONT have! Overall, it’s an amazing app- I am a student and it’s such a great student calculator!

"body": "The app's page shows an option for a 7 day free trial. I'm testing out a few graphing calculators in lieu of buying a physical TI-84. The app installed fine but when it opened, I got the error \"product not available\"; the free trial is apparently no longer available despite being listed on its page. So I'm unable to perform even the most basic graphing functions. I need it for a math-heavy degree but it's useless if I'm unable to test it--other graphing calculators I've tested haven't been consistent (correct) in their calculations, so being able to test before subscribing for a whopping $30 per year is a must!",

"body": "The icon depicts the application creating a graph, so I did expect it to create a graph at least once. I understand it's got in-app purchases, but if it will graph anything for users who are still trying to assess whether this app will serve their needs before buying anything, I was unable to tell how. Entering an equation for a parabola yielded a constant when I tried entering it at the first prompt and when I clicked the \"graph\" button I wasn't allowed to enter anything before being confronted with an ad. This app might rock the casbah, but it gave no indication what kind of behavior it would provide to those who chose to risk paying money to see.",

"body": "Pretty similar to TI-84 CE, but needs to enumerate clearly what features are PRO exclusive and which ones aren’t. For the price of $0 compared to its 150 dollar counterpart, I’d say it’s pretty good. Sadly, haven’t been able to do much statistics on here (regression, test values). It can graph, but it can’t do calculus or find max. It’s also missing an equation solver (but has a quadratic equation solver). Actually now that I think about it it can pretty much only graph and do the same things the built in calculator can. But still a decent value compared to the 150$. Plus since you already carry your phone around, it’s not bad.",

"title": "Meh",
"body": "I paid 29 dollars to have this forever. And compared to playing 100$ for a real one that’s a pretty good deal. bUt, I’ve run into some issues with the calculator. Specifically when solving lengthy equations, it never carries the negative through the problem. For example, if I were to put in -3•4 I would get -12, but then I multiply my answer by 8, (-12•8) and it would give me positive 96, rather than -96. This has caused a few issues on some assignments for me but once I figured out what was happening it was pretty easy to continue. I also have a hard time looking at graphs when I graph them. I’ll put my equations into the Y= and it will graph fine, but I can never see the full graph, and because of that I can’t find the intersections and all that. Other than that it works pretty good, I just try to use it for the more basic stuff that my phone’s calculator can’t do.",

You can’t graph certain things but most everything is free. This is such a great app, and I have so much fun creating my own calcular and deciding all the fun colors. It also has other feature that standard graphic calculators DONT have! Overall, it’s an amazing app- I am a student and it’s such a great student calculator!",

This feature is great if you work on different math problems at the same time or want to save your recent calculations but start with a fresh screen. + Tab and hold any button to access the second function behind it. For example, if you want to use sin-1 you can press \"shift\" -> \"sin\" or now just press and hold on \"sin\" until you see that shift commands are highlighted. + With this update you export your graph window as an image or PDF and share it with your friends or save it for yourself. Press the \"graph\" button and you will see a new little icon on the right. You can also save or share a full-screen graph. + iPad users are now able to enjoy Taculator in landscape mode and use multitasking with split-screen. This enables you to use your calculator together with another app. Furthermore, here's the detailed list of new calculator commands. + Draw circles with specified radius and x- and y-value. + Seconds \" button now available. Press the Shift button and \"+\" button to use it. + New Angle commands to convert coordinates from Polar to Cartesian coordinates and vice versa: R►Pr(, R►Pθ(, P►Rx(, P►Ry( + New Matrix commands: Fill( (fill a list or matrix with numbers) and randM (generate a random number matrix). + A ton of new statistical tests: 2-SampZTest, 2-SampTTest, 1-PropZTest, 2-PropZTest, 2-SampZInt, 2-SampTInt, 1-PropZInt. + New regressions added to STATS menu: LnReg, PwrReg, Logistic, SinReg. + geometpdf and geometcdf added to the Distribution menu."
