Frequently Asked Questions
Yes. LVL is BLE enabled, allowing it to communicate with phones, tablets, watches, bike computers and other connected devices.
This allows LVL to transmit real time notifications to the phone when it identifies important body trends as well as continuously stream heart rate and hydration data to other devices, such as watches.Last updated:
Yes! LVL comes with a free mobile app (for Android and iOS) which provides a rich user experience of your current hydration level with real-time recommendations as well as the ability to see historical trends and patterns. The mobile app will be available for worldwide download.Last updated:
LVL comes with on device memory to store your important data even when your phone is not nearby. This allows LVL to track and record on its own so that a phone is not required for real-time use. Once LVL detects your phone, it will automatically begin transmitting your stored data to the phone and syncing to your cloud-based account at onelvl.com via the free mobile app.Last updated:
Yes, LVL has an IP67 water resistance rating. This means it is ok to exercise, sweat, shower and even take it swimming for brief periods of time (up to 30 minutes at 1 meter of submersion).Last updated:
Yes. LVL will include a developer API to be able to integrate LVL data into third party applications. This includes hydration, heart rate, calories, steps and basic sleep quality data.
The SDK includes a library and multiple examples on how to communicate with the BLE interface of the LVL and will be available for mobile platforms (Obj-C, Swift, for iOS, Java for Android).
By being an early adopter of the SDK you will have direct influence on its feature set and evolution.Last updated:
LVL directly measures the water content in the body using our proprietary and patented red light technology (NIRS). This red light is shined into the body using specialized and consumer grade LEDs. As the light passes through the body, each wavelength is absorbed and reshaped in a unique way that allows us to generate a spectrographic 'picture' of the water content and other physiologic activities happening in the body at that point in time. It is very similar to what happens when visible light hits our eyes, allowing us to see.
For example, as light from the sun hits a flower, it is either absorbed or reflected back to our eyes in a unique way that is characteristic of the pigments in that flower - its stem, leaves, petals, etc. These pigments either absorb the visible light or reflect it back to our eyes to create the perception of blue, green, purple or any other color. While our eyes produce photographic images of this pattern, the LVL creates a spectrographic image that contains information of water content and location, heart rate, blood flow and characteristics, etc.
For a more in-depth discussion of how red light technology works and the difference between the red light we use and the green light used in other optical watches, please read the following post on our blog. http://bit.ly/2cFz0UpLast updated:
The optical technology used in LVL has been extensively tested and validated. It originates from the medical device industry where NIRS systems are FDA approved and used routinely in the Emergency Department, Operating Room, Nurseries and Intensive Care Units. In 2012 we spun this technology out of the hospital and into BSX Technologies with the goal of creating a consumer electronic device with similar performance and accuracy standards.
We have conducted thousands of clinical subject trials since that time to develop the technology insides LVL and validate its accuracy. The first product we developed using this technology, BSXinsight, included over 850 subject trials and has been independently validated by numerous third party research and performance institutions throughout the world.
The technology used in LVL is a continuation and refinement of the same technology used in BSXinsight and is the result of the past 4.5 years of intense scientific discovery. We continue to conduct hundreds of clinical trials every month in our laboratories in Austin, TX. All of our hydration validation studies are conducted with and compared against medical gold standards. This includes blood measurements (serum osmolality, Hemoglobin / Hematorcit, Electrolytes), urine measurements (urine osmolality and urine specific gravity), and body weight changes. For heart rate we validate against EKG.
We have partnered with the Korey Stringer Institute at the University of Connecticut to conduct independent validation studies of LVL this next spring once beta units are complete.Last updated:
Yes. LVL is safe to use for continuous, 24/7 wear. The red light technology in LVL stems for the medical device world where it has been used for decades in hospital applications. (think of the red light on patient's fingers that are widely used for measuring pulse oximetery) Many studies have been done demonstrating safety.Last updated:
This is a great question, worthy of a several hour long medical discussion. The simple answer is this: you should always drink when you're thirsty. But the absence of thirst does not mean that you should stop drinking. Numerous studies have been done showing that the vast majority of us (over 75%) are in a chronic state of dehydration. This goes up to 90%+ in elderly populations where the thirst drive is not as strong and access can be more difficult. The presence of fats and sugars in our diet can significantly depress the thirst drive. Even athletes are not immune, where recent studies have shown that during exercise, athletes who drink at will only consume 30-70% of the actual volume lost. Furthermore scientists at Purdue have shown that people seldom drink then they're thirsty, instead they simply drink when they eat.
Why this happens is a more difficult question and many very good theories exist. But due to the complexities of the hydration equation (gender, body mass, age, BMR and sweat rate, temperature, altitude, humidity, exercise, amount of fluid consumed through food, etc) it is a very difficult and individualized questions to answer. This is why generalized recommendations of 8 glasses of water per day are so inaccurate and real-time measurement is so important.Last updated:
