Nike casually let slip today that Nike+, its online platform for tracking personal exercise logged with a FuelBand, SportWatch or Nike+ fitness app, now has over 18 million members worldwide.

Activity is quantified as NikeFuel, a somewhat ambiguous metric that allows fitness enthusiasts to compare their performance and daily routines across multiple disciplines. There’s still no Nike FuelBand app for Android though – the company has admitted that it’s not in development at the moment – which has only added to the popularity of other fitness wearables such as Fitbit, UP by Jawbone and Withings Pulse.

Nevertheless, 18 million is still a sizeable userbase for a firm that is a sportswear brand first, technology company second. Nike continues to develop and update the Nike+ platform – challenges were recently added to the Nike+ Running app for iOS – but it’ll be interesting to see whether it releases a new FuelBand to combat the approaching wave of smartwatches.
