Description
To train at your peak, you can’t just train hard. You need to train in a way that’s informed by your personal biology.
The Nix Solo app allows users to monitor their own personal fluid and electrolyte losses in real time during a workout using the Nix Hydration Biosensor. This companion app provides valuable insight into their unique sweat composition and individual hydration needs based on their personal biology.
At Nix, we built the first biosensor to analyze sweat and provide endurance athletes with personal hydration data – scientifically validated, and delivered in real time.
Once paired with the Nix Hydration Biosensor, you are on your way to understanding your hydration needs with Nix Solo, our individual monitoring app. We’re the first hydration biosensor of its kind — the only pod, patch, and free app combination to:
- Evaluate the electrochemical biomarkers in your sweat
- Send real-time updates to your phone, Apple Watch, Garmin Watch, or Garmin Bike Computer
- Correlate your sweat data and your training environment with the Nix Index – a composite index of six environmental factors: temperature, humidity, dew point, altitude, wind speed, and solar load
- Provide post workout Sweat Intelligence via insights on your Sweat Profile including fluid loss rate, electrolyte loss rate and sweat composition metrics
Before your workout, tell the Nix Solo app what type of workout you’re doing and what you’ll be hydrating with. You can also consult the Nix Index to see how your environment impacts your hydration needs.
Once you start sweating, our single-use patch begins measuring and analyzing your fluid and electrolyte losses minute by minute- metrics that represent your unique “sweat composition.” This data is instantly streamed to our app, and can also be shared with devices like your Apple Watch, Garmin Watch, and Garmin bike computer.
The result is knowing when, what, and how much to drink in real time to enhance both safety and performance.

Ratings and Reviews
Use the Insights After Your Workout
This app is not very good as it crashes all the time during workouts. It also doesn’t notify you very well even when it is running. So I have stopped relying on it to cue me when to drink water. Instead I’ve used the overall electrolyte and fluid loss data to learn how to better hydrate during my workout. Even if the the app crashes during a workout, just restart the app and it will still download the data from the sensor. So you can collect workouts over time to learn how much you expell in various conditions. Just don’t expect it to notify you properly during a workout. Still very insightful data.
Quirky but improving
Have been using the Nix system for a couple of months now. When it works, it is spot on with the information. Due to previous issues, I now place the pod on the patch and start the app all the way to starting a workout to make sure everything is going to work; saves on patches. Newer software releases have addressed some problems. Customer support has been very good with reasonable turnaround times via email.
The app REALLY uses phone battery fast! They are working on it so I expect that it will improve over time. You must be in cell coverage for it to provide real-time info. It may or may not reconnect when coverage comes back. Connectivity to a Garmin device is spotty and they advertise the problem is being addressed.
For shorter rides/event ~4 hrs it’s a pretty good tool and improvements keep coming. For longer events battery and cellular coverage can render the real-time data useless. However, using your past history and the Nix values from previous data it provides you enough information to calculate your fluid and electrolyte requirements.
Needs some improvements, but much more valuable than a single sweat test whose data is based on a single environmental data set. Recommend it as a tool that should improve over time.
Buggy Making it less than Worthless
I can’t get the app to save any data from a full workout. Starts fine and can watch it work for a bit then at end of workout the app says ‘something went wrong’. There is no option to save what it has... only option is to discard workout!?!? Restarting the app and it instantly reconnects and says the patch needs to be replaced… with almost no information presented to user it appears that the patch gets saturated and then app just dumps all the data. I guess I have to stop workout early to save any data?
