On Thursday, Mark Zuckerberg unveiled Instagram Threads, an app that will compete with Twitter.

The App Store listing’s pictures indicate that Threads will operate similarly to Twitter, with text-based messages that can be liked, shared, and commented on.

As of today, the app has over 100 million downloads in just 24 hours, surpassing chat as the most popular social networking program, according to Zuckerberg.

Here are the five things to know about Threads:

4. Threads is closely connected with Instagram, and will likely experience similar character features of 125 caption characters, 150 characters for Bio, and 30 characters for user name.

5. It may likely not face reading limits but action limits of 500 actions a day (including following, unfollowing, and liking).
