Meet the Viseeo Doctor V1: a 3-in-1 iPhone accessory that turns your smartphone into a breathalyzer, UV meter, and heart rate monitor. It doesn’t require a separate battery to work and has a free app that you can download to your phone to track your drinking habits and measure your breath alcohol content.
The DV-1 doubles as a UV meter to measure your exposure to ultraviolet rays as you spend time outdoors. It has a Lightning connector, so you won’t have to use a separate adapter to attach it to your phone.[where to get it]
