This product worked well for about 2 months. It seems after a recent software update, it has failed to sync with the iOS app. It no longer connects to nor recognises a wifi router placed within inches of it, even after resetting, and following the troubleshooting guide. Worse, even the Bluetooth sync option only picks up the data from the phone, like steps and exercises done, but not the other way around. I’ve tried everything. It’s no longer smart and worth the money I paid for it. Disappointing product Withings.
