Overall the hardware looks well designed and good value, but the Android app doesn't inspire confidence. First, the app is NOT supported by Google Play - meaning it's not available on the Google Store and instead you have to download the app from Android, which gives you plenty of security risk warnings in the process - while the Apple app seems to do it right on the App Store be available from Apple. Why? Also, the Android version is NOTHING like the Apple version, both of which have completely different interfaces, and the website doesn't give you any details on version numbers or release dates, meaning it's impossible to tell which of the two is the latest version.
