comScore’s report about location-based check-in service users provides an interesting look at that world. ReadWriteWeb summarized it like this.
But, it goes beyond that. Android users are a large percentage of check-in users but does not yet dominate at 36.6%. The combined check-ins by Android, RIM (BlackBerry), and Apple users is huge though: 87.3%. Microsoft Windows Mobile/Phone, Palm webOS (maybe Palm OS?) and Symbian (mostly Nokia) make up the rest of the 12.7%.
comScore reported that 12.6 million users in the U.S. used a check-in service during the 3 months edning March 2011. This is, they say, 7.1% of the U.S. mobile phone population. This is in line with the Pew Internet study published last November that reported 7% of adults who go online with their mobile phone use a location-based service.
Does this mean that U.S. check-in service use has been flat for the six month period when the two data sets were gathered?
