Saw this for $25 and the reviews for the sodium loss seemed decent so thought I’d give it a shot. I just did my first test during a 60min sweet spot workout. I basically am trying this just to gauge how much sodium I need to add tk my bottles and also because I’m a data nerd and enjoy this type of stuff.
Easy enough to use. Basically sweat and sodium elicit color changes on the patch and then when you take a picture of the patch it analyzes those color changes to give you a sweat and sodium loss range.
From the reviews I’ve read seems like most are suggesting doing this 4-5x to get a decent sample size and then take the average within that.
The app itself is hot garbage but I only want the raw data so it’s of minimal importance to me.
