That's according to Sensor Tower, a market intelligence firm whose data shows Taobao shot to first place in Apple's Singapore App Store across all categories, as of Sept. 11. On Tuesday, the day the English-language version was announced, the app rose from fifth to first place in the shopping category.
Prior to this, the Taobao app had still enjoyed relative popularity and was consistently ranked in the top ten shopping apps for iPhone users from mid-August onwards, according to Sensor Tower.
