I like that you can connect with other users by connecting an Android or iOS device via QR code technology. Since it's connected through Google Play / Apple App Store this also enables third party apps which may have extra features but are not supported here (yet). It works very well for us - we use it in-store. There really isn't much else that would need improvement at this time. We're solving problems related to how people understand their own data and how they compare themselves across departments or industries.
