Buried in the chaos that was Twitter earnings this afternoon was a small nugget on the popularity of the company’s new livestreaming app, Periscope.
CEO Dick Costolo said on the earnings call that Periscope added a million new users in the app’s first 10 days on the market.
It’s a relatively impressive number considering competitor Meerkat was at 120,000 users three weeks after it launched. (Periscope, of course, benefitted from the buzz Meerkat generated and also the fact that it had a well-known owner to help push the news.) It’s unclear if Periscope was able to sustain that growth — when pressed for more metrics on the app and its user base, Costolo declined to share anything further.
Periscope launched in late March after Twitter acquired it back in January. The app is still not available to Android users.
