FLOWBIO Reviews 

Fantastic product. Very insightful data and variations thereof ( bike vs run ), triggering a full review of my fueling strategy. A couple of misreadings in the beginning, but all gone now. Watch import duties, can make it pricey though. Sadly not compatible with my Wahoo Bolt 2.

Had to send it back. Kept getting data corrupt due to movement on skin every time I used it. Tried everything but couldn't get any sodium data. Sweat data was okay though. The flowbio app needs work. Couldn't delete any saved session on app. Maybe I received a faulty product but never the less I sent it back and got a full refund. Will try another sensor now to try and get sodium data.

Great service, responsive costumer service, quick shipping and just a great tool for tracking

Flowbio sensor has been an eye opener for me and has become a useful tool for daily use in relation to my training. it helps me to hydrate better, hence recover better, not cramp and hence perform much better.
The customer support has also been excellent and really cannot complain about them.

I was struggling getting to know how to record my data. One email request explaining my issue and customer service solved my problem. Thank you for helping me! I look forward to using this tool.

It's really helping me to know my sweat loss in each training sessions.at last I found what I want

Había corrido 4 maratones de las Six Mayors, y en todas tuve unas leves contracturas que me hicieron caminar o correr más lento, y así evitar los calambres, para terminar los 42km. Todo indicaba una falta de suplementación correcta, y como sudaba mucho, lo más probable era por la pérdida del sodio.
Para la Maratón de Tokyo, adquirí el FLOWBIO, que me dio los valores precisos de pérdida de solio y agua. Pude verificar con certeza que mi suplementación no era la correcta. Con la ayuda de la Profesional Inés Morán, del staff de FLOWBIO, realizamos un plan personalizado de hidratación y consumo de sodio, lo que finalmente me ayudó a terminar la Maratón en mejores condiciones y sin los temidos calambres o contracturas. Ahora voy en busca de la Maratón de Boston para el 2027, y conseguir mi anhelada medalla de las Six Majors !!

Great product from a great company. Always thought I knew how much to drink and how much electrolytes to consume, but I suffered from frequent headaches and sometimes cramps on the bike. Now after a good 6months use, I understand my individual needs more clearly. Getting my hydration and electrolytes nailed has left me feeling fresher, recovering better and I very rarely get headaches now 👍🏼

Best sweat sensor and best app ever, so easy to use so easy to read the data as a professional athlete I can’t train without my sensor !

Have been using the sensor for 5 rides and its not fit for purpose. If the sensor moves, and it will as you are either running or riding, you lose all the data. When you do get any data takes for ever to sync with Garmin

In principle an interesting product, giving a good insight to my sweat rate. But I would like to have more information about the calculation method and the basics behind

Great Device. This is my 4th workout gathering data in my new FlowBio. And the results seems very accurate. With CF the rate at which an Athlete losses sodium and water is 3x or 4X than normal. So getting the right numbers is a must!! Still have to try it in hot weather (above 27C) but so far the recommendation are accurate. Thanks FlowBio

Hattie was extremely knowledgeable.
I am looking forward on continuing to communicate with her.

What an incredible piece of kit! I’ve struggled with cramp for years. Transitioning from bodybuilding to more functional fitness and running, cramp has ruined so many of my events. I could never figure out whether I needed more water, sodium, or potassium — or if it was simply because I was too heavy (100kg).

After using the FLOWBIO device for just three runs, it gave me my half marathon prediction for sodium and water. I ran it today with zero cramp and hit a PB of 1:39:30!

I’m genuinely excited to keep using it to stay on top of my recovery and fine-tune my race-day protocols. 100% recommend!

When I placed my order, I contacted the company to learn more about what was possible and how I could benefit from the data. They took the time to explain everything and provide me with the necessary information. They truly helped me make an informed decision and demonstrated that they take their client relationships seriously.

Very good customer service for an international company, included free drink bottle a nice touch

Simple to use and very responsive people behind the scenes. I bought my sensor before the android app had been released so had to talk to support who were great. Very useful data generated.

Good communication on questions.

I tried this sensor, and it was a game-changer for data and performance insight.

After a few weeks of clear insight into fuelling strategies, I was able to rehydrate properly and wake up feeling ready for the next day of training - previously I was waking up feeling unrecovered and ready to cramp.
