NIX Biosensor 4+

I wanted to like this, but the development around the connectivity needs to be reworked. I started a ride with my phone battery at 90% after 1hr it was drained to 20%!! It’s useless for long rides if the phone is needed. I don’t race with my phone so having the ability to just use my Garmin would be ideal. It’s so unstable in it’s connection. Says give it 20mins for data to appear, after 45mins still nothing and you have to turn bluetooth off and back on. It’s not ready for prime time that’s for sure!

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.

I would say the app and sensor are good when they work, but they basically never do at this point. Email support has been responsive and as helpful as they can be, but when all they can advise is “yes, we know it doesn’t work but we’ll try to make it better at some point in the future”, it doesn’t seem right to ask people to continue paying. I’ve lost a number of workouts (and the $25/four pack patches to go along with them) at this point. They sent some free patches, which was nice, but that didn’t make the app or data recording work any better. I would love to track this data, but my pod will stay in a drawer because it’s not even worth the effort of sticking a patch on before a run.
