Calculate84 for Negative User Reviews

Inverse trig ratios dont workI did inverse cos of 0.78… and it gave me 0.6…, the UI however is beautiful.Version: 1.7.6

Eye-pleasing design, but can’t graph regression linesI wanted to graph a best-fit line for my data, so I sidled over to LinReg. When I inserted Y1 for StoreRegEQ and pressed enter, it said “invalid variable and wouldn’t let me save the equation as a graphing variable. I did the same thing on a real calculator AND another calculator app—and succeeded. So there’s definitely something wrong with the app itself and not my calculations. I desperately hope you guys will fix it in the near future because your app looks really nice and I want to continue using it. I really don’t want to be stuck with the other app which has ugly visuals, tiny font, and a more expensive subscription plan (it works better, but still).Version: 1.7.4

BugsAfter graphing a line I then wanted to graph a parabola. It graphed the line just fine but when I cleared the y= field and entered the formula for a parabola something weird happened. The parabola appeared in the correct position but when I pressed the trace button the points weren’t in the correct position. I had to exit out of the app and open it back up and enter the formula again in order for it to plot the correct points. Otherwise it works and looks nice..Version: 1.7.7

Good but missing a lot of important stuff.So overall this is a pretty good graphing calculator emulator for your phone. I like how it vibrates when you hit buttons on it to let you know that you actually hit the button. so far the answers it gives all seem to be correct also. unfortunately, it is missing a lot of important things. It can do linear regressions, but no other types of regressions. I assume the developer is working on adding those but they should really be near the top of the list. they are part of basic pre-calc so they should be added asap. I will say that as of right now it is definitely the best one available for free because the other ones lock literally everything behind paywalls but still let you download it for free which just seems like a scummy way of boosting downloads. if you add in regressions, i’ll bring my rating up, but it wont be 5 stars until all commands are available..Version: 1.3.7

Good but slowerFunctionality is good, but app is much slower to open, and input initially lags on launch. It used to be more responsive.Version: 1.6.8

Please update the appOn the latest release of iOS for iPhone your app crashes when trying a 2-SampleTInt confidence interval function. Anytime I input my values the app crashes when I “scroll” down to the “Calculate” button. I tried this with lots of different data with the same results for T or Z 2 sample interval functions. I am a lifetime subscriber and paying customer and really rely on this app for school..Version: 1.7.2

Cant graph the Regression EquationFirst thing I tried was to edit the table under Stat which seems to work fine. I then calculated for the Linear regression equation ax+b which it did but was missing a(the slope) and only displayed b(y intercept). When you copy it over to Y= you wont be able to bring the equation up using VARS. This app is not bad for a basic usage as calculator but there are a lot of functions missing..Version: 1.3.7

Needs more functionalityOverall good app, but no ability to use the finance app that a TI graphing calculator would have or the programs button.Version: 1.3.7

Works for a lot but not everythingI use it all the time for school work but I’m unable to find a button for sinusoidal regression, that the Texas Instruments ti-84 has. As sinreg.Version: 1.7.7

No appsOne significant shortcoming is that none of the TI-84 apps are available (if you press the APPS button the only option is quit)..Version: 1.7.8

Gets most things correctThere are a few functions on this app that differ from a ti84 calculator which make it more difficult to enter calculations, as it requires you to input more variables. But it’s only a few things I’ve noticed. Also, the factorial function only sometimes works. Either it says it cannot solve the problem, or it gives me an incorrect number, so I have to use a different app for that..Version: 1.7.5
