In a series of posts late on Friday, a verified account for the network's chief product officer, listed as Billy B., answered questions on the app from people invited to use it during its test phase. One user asked him when the app, which has been available this week for beta testers, would be released to the public, according to screenshots viewed by Reuters.

"We're currently set for release in the Apple App store for Monday Feb. 21," the executive responded.

The launch would restore the former president's presence on social media more than a year after he was banned from Twitter, Facebook and Alphabet's YouTube following the January 6, 2021, attack on the US Capitol by his supporters, after he was accused of posting messages inciting violence.

On February 15, Trump's eldest son Donald Jr posted on Twitter a screenshot of his father's verified @realDonaldTrump Truth Social account with one post, or "truth", that he uploaded on February14: "Get Ready! Your favorite President will see you soon!"

Led by former Republican US representative Devin Nunes, Trump Media & Technology Group (TMTG), the venture behind Truth Social, will join a growing portfolio of technology companies that are positioning themselves as champions of free speech and hope to draw users who feel their views are suppressed on platforms such as Twitter, Facebook and YouTube.

So far none of the companies, which include Twitter competitors Gettr and Parler and video site Rumble, have come close to matching the popularity of their mainstream counterparts.

In addition to the post disclosing Monday's launch date, the screenshots seen by Reuters show the app is now at version 1.0, suggesting it has reached a level ready for public release. As late as Wednesday, it was at version 0.9, according to two people with access to that version.

A representative for TMTG did not immediately respond to a request for comment.

Apple's App Store listing indicates that Truth Social is expected to be released on February 21, a date that a source familiar with the venture confirmed in January. But in recent weeks Nunes had said publicly that the app would launch by the end of March.

On Friday, Nunes was on the app urging users to follow more accounts, share photos and videos and participate in conversations, in an apparent attempt to drum up activity, according to a person with knowledge of the matter.

The chief product officer's other responses during Friday's question-and-answer session suggested the startup's features would resemble those of Twitter.

Asked whether users would be able to edit their "truths," the executive replied "not yet." The ability to edit posts after publication is something Twitter users have long sought.

The next significant feature released on the platform would be direct messages, or DMs, between users, the executive wrote.

The company is also considering allowing users to sign up to receive notifications when others post content, the executive said. He signalled that the ability to block other users would be an important component.

"There will always be block functionality in the app," he wrote.

Truth Social will issue a policy on verified accounts "in the coming weeks," the executive added.

Even as details of the app begin trickling out, TMTG remains mostly shrouded in secrecy and is regarded with skepticism by some in tech and media circles. It is unclear, for example, how the company is funding its current growth.
