The Onavo company claims Snapchat was used by 18.6% of all iPhone owners in the US in June 2013, up 10.5% month-on-month, making it the ninth most popular iPhone app there in terms of usage.
Snapchat – which lets people send photos and videos that self-delete after between one and 10 seconds after being viewed – is still a long way behind Facebook (used by 72.5% of US iPhone owners) and Instagram (36.6%), but Twitter's 26.7% market share is within Snapchat's sights.
Bear in mind that these figures are for one country and device only: Snapchat has been installed between 10m and 50m times on Android smartphones according to the stats on the Google Play store. In June, Nielsen claimed that Snapchat had more than 8m monthly active users in the US across iOS and Android, but its survey only covered adults aged 18 and above.
