TikTok competitor Triller is preparing to go public, but estimates from Apptopia call its self-reported user numbers into question. Per Triller’s S-1 filing, the short-form video app has had 550 million lifetime sign-ups. But market intelligence firm Apptopia estimates that Triller has been downloaded just 73.2 million times since launch in 2015 — that’s 87% lower than Triller’s own reports.
