FX Calculus Problem Solver App Reviews

I like this app so far it is helping me understand calculus step by step. However, it freezes when creating big complex functions. At that point i switched apps

This is the only calculus app that is worth downloading. All the other apps only include chapters to help with specific examples they provide. This app includes a calculus calculator! It helps because it breaks down the problem step by step. No other app has helped me with my calculus class like this one.

This may work if you have basic easy stuff but if you have moderate to advanced stuff, it wont work. I wont recommend this to anyone and its time to delete it!

This app is really awesome!

Even it seems that its free its not... After a while it requires money to continue to solve...

I have to do homework online and we get to see if our answers are correct immediately after submitting them. For all of the functions I put in to differentiate NONE of them were right, and the rest told me they were unsolvable (I DID try re-entering them several times each.) Very untrue, because in the end, I got help and got all of them right with help. I didnt even get the "premium package" to use the solver after I tried it on those functions. Dont upgrade for the solver! It is NOT accurate.

Pointless to download, advertising as free with in app purchase to do anything, dont bother downloading

why its not working with me?

Easy enough to use. Simple application, but you only get a few chances to solve a unique problem before being forced to purchase the premium edition.

I cannot graph more than half of the equations I put in the solver, and so many of the questions I enter do not work. I do not recommend buying this app.

I love the way it shows you step for step some problems. The best app for calculus ever :)

I only write reviews when I am impressed with the app. I am extremely impressed with this calculator "plus". Excellent work. One quirk is having to add keys to the keyboard, however, I can deal with that. Thanks!

Waste of money, cannot solve problems, always displaying a "fail to solve problem" message. Dont buy!!!!

I am not having the failure issue the other user identifies anymore because I learned how to properly input my problems correctly. It was a bit of a learning curve but now I am very pleased with the help this app gives me. I recommend it and use it as a study tool and it has only boosted my abilities. I have even come across the exact same problems in this app on my tests!!! How great is that!? I think a lot of effort and thought went into the app. I do have a question in to support b/c they are distributing ln across addition function and I have always heard that is totally wrong. Ln10(x^3+1) cant be ln 10 x^3 + ln 10 right guys!?? No way. I will update this review to reflect a mistake like that when I find out whats up b/c if there is an error like that I would cease using the app in totality and never look back. Getting taught incorrect methods creates a giant mess in your head. Let ya know!

I downloaded this for help with derivatives and sure it can do basic equations but if you need help with anything advanced this is a complete waste of money!!!!

Amazing App but..... There should be a tutorial on how to use it and also there should be a better way to enter cube root.... Its a very difficult thing to do!

Crashes

It is a little buggy sometimes, but overall it is one of my favorite calculus apps. It will show each individual step to solving a problem as a side show which I really appreciate, can be very helpful. The keyboard could use a little work, but it is significantly better than Wolfram Alphas. Overall I Highly recommend it to any calculus student.

Can solve some more basic problems but isnt able to solve harder custom problems. For example, the app cannot solve a trigonometric substitution integration problem. Buy at your own risk.

I love it, its very helpful. I just wish it had a dy/dx button for implicit differentiation because thats the unit Im on in class and Im somewhat stuck. Other than that, I love it!
