Keyboard input lag This app needs improvement with keyboard input and faster computation. I'll give more stars if the issues are fixed. If the developers are reading this, I have a Samsung S5 just in case u guys are wondering about my device.

Tanner Murphey

Perfect for math Will solve any math problem (at least that I've given it) and even offer a step by step solution! Best app I've gotten in a while

Georg Plaz

could be more usable.. it's quite a pain to use. no way of copying from the input or going back to previous input.. had some interesting input and you follow a link? too bad, your old input is gone..

Eric K. M. Lau

Don't WASTE your money Able to answer just the simplest of questions, like "Top ten countries with the highest GDP per capita?", but then you can just as well find the answer using common search engines. "Which country has the highest numbers of deaths from heart diseases?" is already too difficult for it ---- it will only give you countries having highest numbers of deaths per annum. It never updates since I bought it nearly two years ago, and like many users say, its UI is a big turn-off. In short, doesn't worth the money!!!

Suprateeka R Hegde

Carry the world's knowledge in pocket! An obvious essential! As far as I remember, I use this app almost everyday both at work and home. Given the usefulness and power of this app, I do not want to write about any software issue.

Collin K

Great app This is a great app, it works like the premium version that they offer on their traditional page. Best feature is that it has step by step instructions!

User reviews

Needs quite a bit of improvement! Wolfram Alpha is such a useful service, but this app is such a poor reflection of the real thing. I am grateful that there are step-by-step solutions available, but they are terribly pixelated on my phone's screen because they obviously didn't account for HiDPI screens. I should note that most phones' screens are HiDPI ever since we entered the year 2012. Come on Wolfram, this is pathetic.

I hadn't realised this was available until recently, and promptly bought it as an upgrade for the calculator app I was using, which unfortunately couldn't do good modular arithmetic, and only supported hexadecimal output for integers, not floating point. Alpha is great! I know ask the Mathematica function names sui I can get it to do what I want, otherwise it would be hard on mobile given it doesn't have good autocomplete yet.

Great app, black bar on HTC One ruins it Please please PLEASE add in a software menu button. The black bar at the bottom is driving me insane. Otherwise, great app.

Wolfram Group March 10, 2015

We apologize for the inconvenience this has caused you. Could you please email us more information about the "black bar" showing on your device? Screenshots demonstrating the problem would also be appreciated. Email us further details at android-support@wolframalpha.com. Good program, needs UI improvements The functionality is good, its only failed me on some very hard calculus problems. However, the app needs some work. The built in keyboard is ugly and laggy and sometimes its quite frustrating. Overall its also a very plain looking app. While the main focus is functionality, a material design theme would make it look much better.

The Perfect Math Tutor Put in any problem with the provided keyboard and calculator and it will solve the problem entirely. It will also give you step by step instructions on how to solve the problem. It gives you different types of tutorials and the updates give it constant new methods and patches ant glitches or issues. Probably the best math application to have. You are caring a portable tutor where ever you go. Perfect for High School and College! I recommend this to everyone; worth every penny!

Keyboard doesn't work Which makes this app useless. Also you should update it to fit the android guidelines, it seems like this app was last worked on 2 years ago

Wolfram Group December 3, 2014

We apologize for the inconvenience. Could you please provide us with more information including specific queries where the issue occurs? Send the information to android-support@wolframalpha.com. Barely works (sometimes) This app does nothing right. It has no advances over the website version, fast internet connection is needed, the funky custom keyboard they use makes external keyboards unusable. And that is if the app works. After 10-20 minutes the app simply stops working (invalid appid).

Great if you know how to use it This tool seems to be immensely powerful, and I find the app is particularly useful when I'm doing maths work. Sadly, I feel like it's pushing some users away with its antiquated interface and lack of instructions, if you like. Give new users examples of things that the app can do. Go to the user, rather than waiting for them! :)

Not up to modern basic technology Keyboard is lousy, when you go to the examples, even when I type word for word from examples still seems to only catch one word on the keyboard even when typing simple commands such as largest carnivore dinosaur. Artificial intelligence, lack thereof is downright embarrassing to be paying for an app like this when the assistant app is free and light years ahead of this...

Very slow. Times out most of the times. Step by step solution doesn't even work for me most of the times. Simple problem of integrate root tanx dx times the app out. Not happy with the purchase. Not sure if there's some help / tutorial link either. Atleast not readily available. Was really looking forward to enjoy this app esp. After watching the wolfram language demo video. Disappointed.

Wolfram Group January 27, 2015

You can find example queries by visiting wolframalpha.com or by checking out the Examples section in the in-app menu by pressing and holding the device menu button. If you have other questions, please email us at android-support@wolframalpha.com. Another lackluster update The updates are few and far between, and seem to only be minor tweaks and fixes. Which is unfortunate, because the interface is in MAJOR need of an overhaul. The interface feels antiquated, it seems like they haven't updated it at all since the app's initial release. PLEASE put some time and effort into the app Wolfram, it seems like you've abandoned it.

Times out without explanation After 2 hrs of using (Galaxy S4, latest droid OS 28Dec2014), I see this still has a few bugs and UE issues: 1) If an evaluation "times out" there is no mention of what the problem might be (e.g. erroneous expression or insufficient processing power): Solve[Integrate[√(1+(cosx)^2),{x,0,b}]==7.6404,b], 2) Can't use back button to recall a previously entered input or screen after clicking a link in the lower solutions section, 3) Would be nicer if you could save "favorite expressions" for future reference.
