Ministry of Supply - Mercury 4+

I’m sorry to report the app has never worked for me. The screen where the temperature control shows I’ve never seen that screen other than maybe once. The only thing it knows is if the jacket is “connected” or not. So you can’t control anything with the jacket through the app they just collect data on you. The only thing that works is use the manual button on the jacket itself. Also the app crashes if you want to toggle activity based control.

Bought a vest and jacket from kickstarter campaign. Haven’t used them much though my first wearing of the vest seemed to be comfortable enough. I felt it was warm but I never overheated. I was active when wearing it vs just sitting in the cold. So this review isn’t really so much about the product as the app. The app however seems useless. I am unable to “connect” a 2nd item even though there is a feature for this. Whichever I connect first, it will then fail to find the other one. Also, the video I watched on setting it up suggests there is a slider to adjust heat, maybe in manual mode? Can’t say since I never once saw this slider regardless of what mode is was in. Love the company. Too bad the full features they touted seem a bit of a fail.

I was able to pair the jacket with the app, but it subsequently never recognizes the jacket despite me holding the phone while wearing the jacket. Also, the jacket does not charge your phone as advertised. It does a nice job just using the intrinsic green on button though. But the app is useless.
