The developer of a controversial memory-boosting smartphone application has hit back at claims his software damages phones based on Google’s Android OS.

MemoryUp Personal hit headlines this week when numerous G1 phone owners who’d downloaded the app from the Android App Market began leaving negative feedback. A report by Geek.com cited users claiming that the software had wiped memory cards and locked their G1s.

But developer Peter Liu today labelled the allegations as "pure rumour". “The boosting algorithms employed in MemoryUp are not a disruptive,” he told Register Hardware.

“After I released MemoryUp, I have got many positive feedbacks from customers," he said. "But I do not know why, all of a sudden the rumours begin to spread.”

The app, which is also available in versions that run on the Windows Mobile, Symbian and Blackberry operating systems, is described as “a handy memory optimiser tool” capable of making your smartphone run faster and more efficiently. It's does so by defragmenting memory to free up Ram.

Liu claimed that MemoryUp Personal is “just a simple application” and not capable of, say, deleting memory cards without first asking for the user’s permission.

Although he didn’t promise to investigate the negative claims, Liu did stress that his development and testing team “never cease” to make the app “a better product” for mobile customers. ®
