More than ten million people have downloaded the BlackBerry Messenger (BBM) tool for iPhone and Android devices since the application was made available on Tuesday.
The rush for the messaging platform helped it become the most popular app in numerous countries including the UK, US and Canada. Reviews have been broadly favourable, with a three-star average on the iTunes App Store from more than 2,500 users.
Google Play users were even more positive, with a four-star average from 120,000 reviews and at least 60,000 five-star reviews. The good feedback will be a welcome break from issues that have dogged the company over the last few months.
Andrew Bocking, vice-president for BBM at BlackBerry, said the huge demand for the app proved the firm still had plenty to offer the mobile market. “This has been an incredible launch for BBM across Android and iPhone devices. The mobile messaging market is full of opportunity for BBM,” he said.
“We intend to be the leading private social network for everyone who needs the immediate communication and collaboration of instant messaging combined with the privacy, control and reliability delivered through BBM.”
Tuesday's release came after the firm had originally been forced to pull the app's first launch, which appeared to have gone live early by mistake.
The huge uptake of the app comes amid ongoing uncertainty over the future of BlackBerry, which is currently considering buyout offers from financial instutitions and former directors after the launch of its new BB10 operating system and new devices failed to ignite demand for its products.
