## Most critical reviews (10 lowest-rated)

### 1/5 — It’s crashing moment I open a menu

*2024-09-22*

Frustrating to know a paid app is useless as I cannot use a single module as the app crashes.

**Developer response:** Dear User,

We are sorry to hear that and we would like to help you. Please contact support Aljanahi.hassan@gmail.com. Meanwhile make sure you are on the latest IOS version and that the iPhone isn’t jailbroken.

### 2/5 — paywall

*2024-06-09*

if there was on payments required, this app would be awesome

**Developer response:** Thank you for your review.
We are glad that you find this app to be awesome. We require you to pay to keep the app running. We don’t want to use ads for this app, as they are annoying and invasive at times. But if people don’t mind them, we will introduce the ads. For any suggestions, please contact us at aljanahi.hassan@gmail.com. We strive to help students and make calculus easier. 
Thank you again!

### 3/5 — Practice, not learn

*2022-04-04*

paywall for integrals and summations

**Developer response:** Thank you for the review. People can view that there is a full access in the in-app purchases section. The reason behind it, is that we don’t offer ads to the customers as a lot of users find it annoying and distracting. Also, the lessons and examples questions are from top universities and similar questions are found in their exams. We want to offer the best value for our users and as consequence we have to charge money as little of it as possible to deliver the best experience.

### 3/5 — Needs more organization

*2021-12-29*

As someone who has had calculus before, albeit 20+ years ago, I would’ve expected this to be in some sort of semblance, similar to how you would learn it in a classroom setting. Perhaps number the different areas in the order they are taught/needed to learn before going to the next concept.

**Developer response:** Thank you for your valuable feedback. We cater for different syllabi hence why they are grouped the way that they are. So, the order for each syllabus will be slightly different. To fix this we named the lessons and sections based on all syllabi and the users can traverse the app accordingly. If the user doesn’t have a syllabus to reference, we added the numbering to show the user the ordering of most syllabi. For example, definition of limits then limits at infinity then continuity and lastly tangent line.

### 4/5 — Its informative but too many errors

*2024-12-31*

For example: 
in integration, the simpsons rule integral is x^3 and in the n-1 step they made it x^2
Answer should be 6
Many spelling errors. 
Many notation errors.
Makes it kind of confusing and slows down the process but other than that it seems to be quite concise. 
I seem to learn much more efficiently from this than any other source? Weird.
Thanks.
1$ worth it.
Should add more

**Developer response:** Thank you for the review! We fixed the errors on our new update and as for the notation we are using CIE notation. Thank you for your valuable feedback!

### 4/5 — Very Useful

*2023-01-03*

Ive seen videos about calculus but this helped me understand it to an extra level. The only issue i have with it is that i have to pay to learn integration which in my opinion is kinda dumb. At least we can get a preview of the integration and the other thing without paying. Other than that its quite useful!

### 4/5 — ?

*2021-09-03*

I don’t know anything about calculus yet and I thought I could figure it out with this app and the algebra knowledge I have but it did not. Still pretty neat though

**Developer response:** Good day to you. Glad to hear from you. Do you have any suggestions on how to make the app more helpful to you? Thank you and your input is much appreciated.

### 5/5 — Great app

*2022-12-11*

This is a great app helped me through my first calc class. Does cost a dollar for full access but that’s to be expected. Other apps are way more expensive and do not explain the process as well as this app.

**Developer response:** Thank you for the review. We are really glad that it helped you!

### 5/5 — Need these apps!

*2021-11-14*

With way too many math solver apps and so few math education apps, this and others like it need our support

**Developer response:** Thank you so much for the support! And I hope the app was helpful to you!

### 5/5 — Nicola V Scott

*2018-06-04*

Nicola Vivienne Scott on Apple iTunes Music: This is great!

**Developer response:** Thank you so much on your review. And I hope that it helped you!
