I still advise my clients to make sure they have their check-in accounts set up properly, and I encourage some to be more active in encouraging people to check in by offering various types of rewards. According to Pew, more than 18 percent of all smartphone users used check-in apps in 2012, up from 12 percent the previous year. That really is quite a lot; this year there are about 33 million people using Foursquare alone.
In the end, it’s up to the users to determine whether they see any value—either in rewards or just the gaming aspect of it—in checking in to various places of business. For some, it’s just a matter of keeping a record of what they are doing and where they have been.
