Wolfram Alpha is a good search engine, but you just don’t want to pay $49.99 to purchase their iPhone app. When you visit Wolfram Alpha, the iPhone Safari actually can handle it even there are no mobile version provided. Wolfram Alpha don’t want to lower their price and think they are worth it. In the latest update, they provided additional virtual keyboard for special character input. It includes Greek, symbol and math keyboard. And it may be useful for advanced search query. But, would you buy it because of these new features?
