Good, but needs work.
I love how it works like mathway in the way it shows all of the steps but you only need to pay once instead of monthly. I wouldn't mind if there were ads so they could get a little money towards improving the app though. For example, it fails when I don't have a really really good connection and it does crash a lot when I try more complicated integrals. Sometimes, the menus won't unexpand and I don't have great eyes which makes it harder for me to see. Plus, I keep on having to add extra inputs into the keyboard. I can't save the layout or anything like that. Other than that, it's a pretty well put together app.

Needs organization
Great for simplex problems, but needs a lot of organization. A lot of problems I have I can't input because the sustem doesn't allow it.

Animated Solutions Board is not functioning
Though this application has topics and concepts that are seemingly helpful, there are parts that don’t function as expected. I purchased the premium package sometime ago with an older iPhone... it worked. I have had my iPhone X since they were first released, and the above referenced feature crashes when I attempt to launch it. I sent an email several days ago, but have not heard back from the support team. Hopefully, the app is still supported and is not one of those the developer allows to die on the vine!! On a scale of 1-5 with 5 being highest: Reliability - 1 Quality performance - 1 Customer Service - (-1) off the range Information - 1 Value/Price - 1 Overall, one star until, and if it’s corrected!!

Summation missing.
I have had this app for a couple of years now and Appreciated it greatly until I tried to do a summation. This seems to be a serious flaw considering the manner in which calculus is taught. What is one to do, use an integral instead?

Definite thumbs up.
As a high school math teacher- who left the classroom to raise our daughter- I find this app to be very useful. I remain certified and tutor many students. The problems give me practice and refresh me on concepts that I’ve forgotten. Definite thumbs up.

Worth Every Penny
I'm a Civil Engineering Technician and I need quick and efficient ways to compute derivative and integrals. This app fits the bill perfectly. It would be nice to see curve fitting in the near future.

Excellent
The recent update is much appreciated. This is one of the finest math-review tools I use. In an instant math concepts can be researched and I find my forgotten knowledge refreshed, well done.

This app has been excellent at helping me remember calculus concepts that I might forget. Obviously, there are a few flaws, but it’s pretty good overall.

Crashed.
You have to buy the app after solving a few problems.. So I did only for the app to start crashing. Whenever I would hit the "solve" button, it freezes and crashes. Don't waste your time.

Awesome!
I payed for the app and it's cool! However it needs more capabilities, maybe like INC and DEC coordinates on my graph and what about MiN and Maxima? I guess it'll have to do though..

Good app
This app was somewhat helpful for me. I plugged in some of my homework questions to double check my answers and it for the most part had all of the operations that I needed to complete. Usually gave me all the correct answers!

Very helpful app
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) can't 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 what's 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!

calculus solver
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 Alpha's. Overall I Highly recommend it to any calculus student.

Solver is NOT accurate
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 didn't even get the "premium package" to use the solver after I tried it on those functions. Don't upgrade for the solver! It is NOT accurate.

Worth it.
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.

Wonderful
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!

Great App, One Suggestion
I love it, it's very helpful. I just wish it had a dy/dx button for implicit differentiation because that's the unit I'm on in class and I'm somewhat stuck. Other than that, I love it!

Cool but not worth it.
Can solve some more basic problems but isn't able to solve harder custom problems. For example, the app cannot solve a trigonometric substitution integration problem. Buy at your own risk.

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.
