Problems with app right away

I downloaded the app to my iPhone to use with my new Skyn and I couldn’t check the box to agree with the terms because it was only partially visible on the screen. Rotating phone made no difference.

Had to install app on iPad to complete sign up and be able to use.
Once I completed sign up on app I then was able to login on phone app.

Lacks features

I was very excited about this to track and monitor my drinking but there is no apple health support, no metrics to compare this week to last week etc just real time data. I have emailed the company a few times but no response.

Device works but the app is very limited

Interesting data but I can’t export or sync with the health app. Overall seems like the app needs more investment and thought. Sync with health app and Apple Watch complication would be awesome

Inaccurate

I’m sitting here now with the device saying I have had a moderate amount to drink. I haven’t drank anything in 3 days. I’m not wearing lotion or anything that could set it off, it’s just inaccurate and a waste of money.
