Twitter has over 145 million registered users and more people are using mobile devices to access the microblogging service, according to co-founder Evan Williams.
Williams, in a post on the Twitter blog, also said that nearly 300,000 third-party applications have been developed around the service, which allows users to pepper one another with messages of 140 characters or less.
'These new services help people get the most out of Twitter, contributing to user growth and new business opportunities - both of which are critical to the long-term viability of the ecosystem,' Williams said.
The Twitter chief executive said the number of people using Twitter on mobile devices had jumped 62% since mid-April and 16% of new users start on mobile, up from 5% in April. 46% of active Twitter users regularly use a mobile device, he said.
Twitter acquired a third-party mobile application called Tweetie in April and turned it into the official Twitter programme for Apple's iPhone. Applications also exist for using Twitter on Research in Motion's Blackberry and devices powered by Google's Android mobile operating system.
Williams also published figures on the top 10 applications people have used to access Twitter during the past 30 days. 78% used the official Twitter.com website, 14% used Twitter's mobile website m.twitter.com, 8% SMS, 8% used Twitter for iPhone and 7% used Twitter for Blackberry.
Other applications in the top 10 were TwitPic, a programme for uploading photos, TweetDeck, Echofon, Google Friend Connect and UberTwitter.
Twitter said the numbers add up to more than 100% because people often use more than one application to access the service.
