Review that really sticks

Academic research has found that memories are formed by repeated exposure to new information, so Magoosh’s flashcard app uses a spaced repetition system. Analogies you are learning will reappear frequently (occurring less frequently the better you know them) and analogies you already know won’t be repeated.

Great potential! Love the concept. I would have rated it higher, if there was some sort of time feature, where you can set a difficulity for yourself! Since right now, you can just stare at a single question for hours straight defeating the whole purpose of flash cards which are ment to just be fast and simple.

Wonderful app! However, it would be great if one can set up reminders as well. That would set them up with a consistent habit of reviewing and learning words.

A great app for practising mental maths however a few more examples and problem would make it the best. Also if one can make the interface a bit playfull that would be a cherry on the top

It's a great app to learn new methods of solving simple math problems. I really love this app . If you are fond of learning new methods and improve your math skills then it is a great app to use you just have spend some 20-30 minutes in this app and u can learn alot. I like the way this app works if you get something wrong then that question would appear repeatedly in that way our learning becomes even more productive and we can remember it for longer time. Also checkout other apps recommended.

There are not enough calculations in each category. It would be easy to write almost endlessly different calculations that are in different categories. Now the situation is that the different calculations are memorized and the mental math is not improved but memory. That is, the application needs more different types of calculations in each category.

I like the app, I just don't like the contrast of colors used in the app. It really bothers my eyes. I would use the app a lot more if it were easier on my eyes, I can only use it for about 5 minutes before I need to close the app and take a break. I do enjoy using it when I'm bored and have nothing else to do. It's also great exercise for the brain!

This app is the place where you can actually boost up your speed of solving numericals. Some of their "tips" for solving the problems are unnecessarily confusing. However, my mental math abilities have improved!

Tan. V. May 20, 2019     

um there are a lot of bugs in this app. first of all it doesn't even let me create an account. every time I enter my info it tells me it isn't the right password for my account. but I'm not even on the Login section, so I can't use this app since I can't save my progress. second, the flashcards look like they just reedited the vocabulary magoosh app. they just have "I knew this word/I didn't know this word." but they're not words?? they're numbers??

Challenging problems mean I'm always learning! My one gripe is that the buttons are poorly laid out, making it easy to tap the wrong option. Refinements in design would be appreciated and maybe merit that 5th star.

Apk was good and all but there is one suggestion i would like to give to developer... Please provide us a space to answer questions when you first show example. So we can know how fast we are while solving the question. Once again, its a great application for getting konw how easy maths can be if we use some tricks and break it apart.

Moh. H. Oct 24, 2019     

This app is very helpful. After using it, now my way of solving maths calculation is entirely change. Tricks presented in the App are simple and effective. I recommend this app for someone who is willing to improve his/her maths solving ability. Btw Thanks for the great app.

A good application to improve calculation speed and to use when you're: 1. Waiting in line 2. Waiting for your order 3. Waiting in a hospital 4. Travelling in a metro 5. Travelling in the backseat of a car etc.. It has helped me solve GMAT questions in seconds, because of the practice of course :)

Jen. M. Jul 22, 2019     

Generally, this app works just fine. my biggest issue with it is that some of the flashcards are blank and cause my phone to freeze. Please fix this!

Vij. M. Nov 4, 2019     

Some answers don't show up.. it just hangs on the explanation page and don't show anything other than two bottom options. Hence, can't see/understand the concept.

Jas. T. S. Sep 30, 2020     

Liked it! Especially the tricks you provide behind every card, it really helps to solve the problems quickly and easily.

Kri. R. Aug 8, 2021     

Very good app with exactly what you need to train your mental math ability. Simple and not complicated as it requires minimal clicks between cards to keep you going

Tin. M. Nov 17, 2021     

The flashcards show sample sentences for context rather than simple definitions; you can also play against other people to really test your progress and speed.

Gui. U. Dec 31, 2021     

I think is a nice app, nevertheless, I think that the flash cards works pretty good with the IELTS preparation test. However for the GRE I was expecting a better app.

Sor. D. Jan 16, 2022     

kinda lackluster -- it's OK...just doesn't give meaningful practice, at least not for math. It's the equivalent of counting sheep to fall asleep.

Dan. G. Aug 14, 2021     

Perfectly simple, has everything you need without needing to connect to the internet. Its explanations for the different approaches you can take to solve problems are very helpful :)

Jul. Z. May 1, 2020     

Great app, I haven't done math for awhile, it seems that my brain need some exercise on it. This app helps people like me who are not very fond of math to improve gradually 👍👍

Jee. K. V. Dec 19, 2021     

It has been a great app for me. I was very slow in calculations but this app is making me do it faster than before. And, the best part is that it's totally free!

Chr. N. Apr 15, 2022     

I found this app easier to use than other apps teaching math tricks. Not only that but it is free as well

A. G. u. Oct 17, 2018     

Very challenging. I was a bit unhappy with the simplicity of the questions. I was tempted to use paper many times but did not.

Tan. Jul 20, 2020     

This app is the place where you can actually boost up your speed of solving numericals. I would like to suggest that make your app look a bit creative and interesting.

Pau. J. Jun 1, 2019     

I'm having some issues creating an account . Also have a button to go back to the previous question if you accidentally pressed the wrong option. Apart from that this is exactly what i need in my life

Sar. S. Nov 7, 2018     

Good tips for solving simple numerical calculations in mind. Thanks. But please increase more topics and tips since the coverage is quite limited at present.

Aru. T. Dec 11, 2019     

Magoosh is the best learning platform for exams like GRE, GMAT, IELTS etc. I opted for GRE coaching and can't begin to explain how incredible the student support is. These free apps are a cherry on the cake. 😄

Its a good practice app. Straight forward. Tricks for simple calculations can b learnt . My 9 year improved her calculation skills
