Former US president Donald Trump’s new media venture plans to launch its social media app Truth Social on February 21, according to an Apple App Store listing.

Truth Social, the Trump Media & Technology Group rival to Twitter, is available for pre-order before going live on the US Presidents’ Day holiday.

Similar to Twitter, the app offers features to follow other people and trending topics, according to demo photos.

Its equivalent of a tweet will be dubbed a ‘truth’.

The app’s launch would come 13 months after Facebook and Twitter banned Trump for encouraging his supporters to participate in the January 6 attack on the US Capitol based on unsubstantiated claims of widespread fraud in the 2020 presidential election.

Marking the one-year anniversary of the attack, US President Joe Biden on Thursday said his predecessor’s false claims could unravel the rule of law and subvert future elections.

TMTG and Apple did not respond to requests for comment but a source familiar with the matter confirmed February 21 as the planned launch date of the app.

The launch is expected to be the first of three stages in TMTG’s development.

The second would be a subscription video-on-demand service called TMTG+ with entertainment, news and podcasts, according to the company website.

A November investor presentation indicated TMTG also wants to launch a podcast network.

TMTG is valued at $US5.3 billion ($A7.4 billion) based on the stock price of Digital World Acquisition, which rose 20 per cent after Reuters reported the app’s listing on the App Store.

TMTG agreed in October to merge with the blank-cheque firm at a valuation of $US875 million ($A1.2 billion).

Trump supporters and retail investors have snapped up Digital World’s stock, betting Trump’s popularity with his Republican political base will translate into commercial success.

The blank-cheque acquisition deal faces regulatory risk.

Democratic US Senator Elizabeth Warren last month asked the US Securities and Exchange Commission Chairman Gary Gensler to investigate the planned merger for potential violations of securities laws around disclosure.

The SEC has declined to comment on whether it plans any action.

TMTG last month raised an additional $US1 billion ($A1.4 billion) from private investors.

Trump cancelled a news conference at his Mar-a-Lago estate in Florida that had been scheduled for January 6, marking the one-year anniversary of the Capitol attack.

He said he will instead deliver remarks at a rally in Arizona on January 15.
