If you don't have Wolfram Alpha .... ....You are really missing out. A great information application. Its like having a personal Jarvis electronic assistant. Typing information into this application always reveals something great !

Dustin Ginos

Better now Now that it works again this app is great. Thanks for getting an update out so fast

Martin Abram

Great So far this has been a great help, but well I should say that it is quite sad that on mobile version we can't use long sentence unlike on desktop. I hope that mobile version can use the long sentence search

Raquel Pearson

Very helpful Definitely worth the buy. Personally, I struggle a lot with math, I like this app because it breaks everything and teaches you how to do the math while giving the correct answer.

Spliffy J

Distinction reason This app help me alot with math, and with some hard work and step by step solutions I got n distinction :)

We apologize for the inconvenience. We have released an update that should address the issue. Please let us know if you are still having problems by emailing us at android-support@wolframalpha.com. Subpar calculator with annoying bugs. On results activity, pressing "Show More" button still crashes the app.

Wolfram Group June 9, 2015

We apologize for the inconvenience. Could you please send us more information and specific queries where you see this issue occurring? You can email us at android-support@wolframalpha.com Network error now fixed An unaddressed and persistent network error after two updates made app unusable for many weeks. Other users' queries regarding the error failed to elicit a fix from the developer. Given it is a paid app, I deplore the time the developer took to rectify the error. I am a new user to WolframAlpha and it has been mighty frustrating to have it fail so completely for so long, just when I had the time to become interested in learning how to use it on my phone. Like so many online things, there is no recourse. It's not like there is much competition for this type of app that users can switch to, so I feel quite peeved to say the least. However, now that the developer has graced us with his responses and finally fixed the fundamental-to-operation network error, I can finally use the app I paid for ages ago. It is about time this, and other paid developers with similar poor response times were held accountable in some way. I doubt that will ever happen. I just thought I'd put the idea out there. As for my review of the app... I have no idea yet. I will use it for a few months and see if it sparks my interest to edit this review a third time. Thank you,

Wolfram Group June 2, 2015

We apologize for the inconvenience. We have released an update that should address the issue.

We apologize for the inconvenience. We have released an update that should address the issue. Please let us know if you are still having problems by emailing us at android-support@wolframalpha.com. Network error The app is great, it does everything you could expect from wolfram alpha. However it seems as they do not pay to much attention to making it better. Aesthetically it is outdated and some functionality like the custom keyboard does not work well

We apologize for the inconvenience. We have released an update that should address the issue. Please let us know if you are still having problems by emailing us at android-support@wolframalpha.com. Great app...deserves an extra star. helped me alot with my advanced math when i am in a pinch saving me time from long calculus solving problems. The only downside is you become lazy and you can't take this into your exam. One small bug...at times backspace button stops working...on refreshing the app it works again. Look into it please.

We apologize for the inconvenience. We have released an update that should address the issue. Please let us know if you are still having problems by emailing us at android-support@wolframalpha.com. Plenty of uses Now that the network error has been corrected, the program is useful once again! Author of app was very fast at getting a patch out so 5 stars from me once again :-)

We apologize for the inconvenience. We have released an update that should address the issue. Please let us know if you are still having problems by emailing us at android-support@wolframalpha.com. Wolfram alpha is great but... Wolfram alpha website is great, unfortunately this app seems to be just the website wrapped in an embedded browser. Might as well use the website. Only used once but found it slow and unimpressive. Graphs in particular were not very interactive zooming in on a particular region was very painful.
