All hell broke loose last week when Nike relaunched its much loved Nike+ Running app with a new offering called “Nike+ Run Club.” Plagued with bugs, sluggish performance and missing features, this update has infuriated some of Nike’s most loyal users, including me. Nike+ Running used to have an impressive 4.5 star rating on the App Store. Since the update, this has plummeted to just 1.5 stars. And Nike’s Facebook and Twitter accounts are now flooded with gripes.
So what happened? How could a single update turn one of the best iPhone running apps into one of the worst?
But which one will be most damaging, and which will quickly be forgotten? Apple’s tax fight is sure to rage on for months, but will faulty phones leave a bad taste in the mouths of Samsung fans a lot longer?
