## Most critical reviews (10 lowest-rated)

### 1/5 — Nice App but...

*2021-01-31*

This is a good app. However, the explanations need to be a bit more towards beginners and need to be understood by beginners. Explain the notation properly and let the solutions be more in-depth

### 2/5 — 1-1 Practice problem 5 answer is wrong

*2021-02-16, version 1.2*

48510/14700 is 33/10 not 36/10 thus the answer is wrong.

### 4/5 — HELP!!

*2022-10-05, version 1.2*

App is usually great, but is force closing by itself lately. It doesn’t seem like there’s an update available. Is there something that can be done? Thank you!

### 4/5 — Great for first time learners

*2015-07-29, version 1.2*

This app is great help. It has what you need to know to succeed in this course and also has some practice problems aside from the context reading, this is great

### 5/5 — Great practice while at lunch

*2026-03-15, version 1.2*

I only hope we could write on the question page.  It’s free, no ads.  Better than doomscrolling.

### 5/5 — Incredible

*2023-07-18, version 1.2*

Extraordinary

### 5/5 — This app is GOOD

*2022-12-27, version 1.2*

This is the best app for calculus ever and it is so easy to use and learn how to do calculus

### 5/5 — Just started using but seems pretty good

*2022-10-13, version 1.2*

5 stars for useful completely free product.  Thankyou! Wanting to go back to uni and need to revise some basic mathematics knowledge and the discipline of problem solving. Great to have these solutions at hand. Not really set up for teaching yourself from scratch.

### 5/5 — In depth practical course

*2020-06-28, version 1.2*

It almost covers all the core topics and gives you great start as a fresh student in your uni study

Many thanks for the excellent work

### 5/5 — Can you fix the mistake, please?

*2019-07-31, version 1.2*

It’s amazing! Great for practice and stuff.

(However, there is a mistake! In 
Numbers -> Rational Numbers -> Problem 5,
There is a mistake in step 3-4!

You see, 4851/100 * 10/147 is actually 33/10, not 36/10.
Therefore the solution is actually -100, not -115.)
