WolframAlpha Classic

★★★★★ Nyi Min Hut It is a great app and I don't expect that much from the beginning.​ But needs some improvement in UI.

★★★★★ A steal for USD 3 quid! The step-by-step solutions to all kinds of math problems are excellent. I am not aware of any other service that provides such high quality and is so cheap. No subscription.

★★★★★ Wolfram = Awesome! This app however, could really use: * UI: a dark mode setting. * UI: swipe-down-on-keyboard to hide keyboard. (wasn't obvious, but swipe-left-from-screen's-right-edge will hide the wolfram keyboard.)

★★★★★ Which Wolfram Alpha did I pay for? These apps have nearly identical names. One is yellow, and the other is white. I just want the app I purchased.

★★☆☆☆ Bait and switch for this originally paid version that I paid for that now has extra versions that have monthly subscriptions. I paid for it, now you add in in-app purchases? Not acceptable

★★☆☆☆ This app is fairly amazing, and it WAS a great purchase until just like almost every other application that we all thought would be a one-time purchase, the developers decided to make numerous levels of pro, pro+ monthly subscription options, and a new version of the app which from reading the reviews, not to many people care for. Most Importantly, I noticed the developers didn't care to include in the app description that it contains in-app purchases... Probably because it originally DIDN'T!
