Wolfram Alpha drops app price from $50 to $2

Wolfram Alpha on the iPhone

Wolfram Alpha has dramatically dropped the price of its iPhone app from $50 to $2, saying it wanted "ubiquity".

The announcement highlighted the company's one-year anniversary and new focus on availability and getting Wolfram Alpha "into the hands of everyone."

"We want Wolfram Alpha to become ubiquitous," wrote Schoeller Porter on the firm's blog.

"Many, if not most, of our mobile customers tell us that the app is their preferred way of using Wolfram Alpha," he added.

Wolfram Alpha will be offering refunds to any "early adopters" who bought the pricey first version.

The online tool, which answers questions instead of offering up web pages like standard search engines, will also now offer a mobile-friendly version of the site.
