Nice hardware, shame about the app
This seems to apply to most of the Withings 'ecosystem'. I've been using the Pulse and Smart Body Analyser (=WiFi scales) for 18months but the Android app is still, after all that time, almost unusable. They introduced a new 'Timeline' display a little while ago, but that has even worse synchronisation issues than the original Dashboard. If you report any bug their first response is to uninstall and reinstall the app. This loses all your personalisation setting so you have to go through the painful setup all over again. The bug is usually still there afterwards! Also, the web app has its own settings, some of which are reflected in the mobile app, but some have weird side effects. As the reviewer says, "...when app and hardware are both part of the 'product', a weakness in one is a fault in the other."
