The shift has boosted right-wing favorites like Parler, Newsmax and Rumble which have rejected the approach of Facebook and Twitter in labeling and limiting the reach of conspiracy theories.
Parler, founded in 2018, saw more than 3.3 million downloads from Apple and Google marketplaces since November 3 to reach 7.3 million installs globally, according to market tracker Sensor Tower.
Large gains were also seen for other conservative-friendly services such as Newsmax - which Mr Trump himself endorsed - as well as MeWe and Rumble.
These sites have left up Mr Trump's claims of manipulation of election results in states he lost.
