The prototype was worn through real training sessions, logging salinity trends alongside heart rate — then handed out to the club to see how it held up outside a controlled test.

Feedback from the coach and swimmers who tested it
"Shruti has been part of my club since childhood. While she has excelled in swimming, she has also enabled other peers in her club to improve their performance. She has come with a device which measures salt concentration in the sweat thereby allowing swimmers to understand their level of dehydration. She has tested on 15 swimmers and demonstrated its ability to accurately measure the salt concentration. Considering this is a difficult task to do in swimmers, I see a lot of value for the device — one that will bring about a positive change in the swimming community."
Coach Sandip
"Shruti has been our senior in this club at Powai. She has always been willing to give us guidance and provide inputs whenever required. I was excited to see the device which she has come up with. I feel it's going to be of great help to the emerging swimmers."

"This device is a novelty in itself. Seeing the device work in front of our eyes was an amazing experience. I was able to take remedial measures as soon as I saw a spike in the salt concentration levels. I wish Shruti all the best for her future endeavours."
