Recently, Twitter tested a new beta app. The new app will be used by the company to beta test social network changes before the changes are widely implemented across the platform. Currently, enhanced conversations are tested by using different colored bubbles to respond to a tweet.
Twttr is not open to everyone. You need to log in and then be included in the program.
To register, visit this survey page and answer a few questions. You'll need to specify your Twitter handle and specify which device you use Twitter most often, in your main language and the country you live in.
After submitting the form, you are cautioned that the program is currently only searching for iOS users who speak English or Japanese. But even if you do not meet these requirements, filling the survey anyway is not a bad idea. You never know when Twitter will open the program to more people.
Those who have been selected to test Twttr will receive an email from Twitter over the next few days, either with instructions to help them install the app. If you are not selected, you will receive an e-mail informing you that you have been put on a waiting list.
