Blink mobile app already works on Android tablets. It has from the start. However, to support newer and better Blink features, older versions of Android and IOS are no longer supported.
There was and is no intent to support laptops and desktops. Why? Because Blink is a mobile app to be used on mobile devices.
I gotta ask, why is a 70 year old with a screen name slow learner purchasing all 3 brands?
