I love how easy they've made it to take a test I love how easy they've made it to take a test + the in-app experience is really awesome. Love the recommendations. Love that it only takes 90 seconds for the test to be submitted. It would be useful to also have potassium since it works hand in hand with sodium, but it's probably more complicated. Overall amazing experience.

This test wasn't accurate for me Following from the response from Vivoo I will always consider a blood test to be more reliable. I won't be buying this product again. This test wasn't accurate for me. It stated low sodium. I actually did a blood test on the same day and it showed sodium levels were in the high end of normal range. My hydration is low but I drink 3 liters of water daily. How reliable are the other results?

I feel more empowered since I started… I feel more empowered since I started to use these tests. I don’t know if they work but it helped me to up my Vitamin C intake and start to eat better. I realized that I sleep much better since I started to count nutrients rather than calories. I’m cutting one star as my sodium tests didn't give a reading.

I absolutely adore (adore!) keeping… I absolutely adore (adore!) keeping track of my Vitamin C intake! It's a bit pricey, but it's so much simpler than constantly referring to color charts and jotting things down in a notebook. By the way, could you kindly include potassium as well? That would be fantastic!

It is super easy to use It is super easy to use, and I love how it gives personalized tips on staying hydrated. As someone who's into sports, Vivoo has made a significant difference for me. The app's reminders help me stay on track during workouts. Overall, it's been a helpful tool in keeping me hydrated and feeling my best while exercising.
