Accolades

all features

Sleep, Readiness, & Activity scores are just the beginning. Your BioRingo Membership also includes:

Sleep

Sleep Score

Your Sleep Score answers, “how well did you sleep last night?”, based on data points including: total sleep, how much time you spent in each sleep stage, HRV, and more.

Automatic Nap Detection

Oura automatically records your naps and adjusts your daily scores.

Bedtime Guidance

Personalized recommendations for when to start winding down, so that you can maximize each night’s sleep.

Blood oxygen sensing (SpO2)

By detecting your blood oxygen levels at night, Oura can tell if you’re experiencing any breathing disturbances.

Readiness

Readiness Score

Readiness is a holistic picture of your health — taking into account your recent activity, sleep patterns, and key biometric signals.

Rest Mode

Rest Mode is activated when Oura detects that you’re tired, unwell, or under stress. Your daily goals will be adjusted so you can put rest and recovery first.

Trends

See daily, weekly, and monthly calendar views of your key body metrics.

Restorative Time

Track physical and mental recovery by understanding how much time you spend in a relaxed state each day.

Activity Score

Your Activity Score is comprised of three core pillars — inactivity, activity level, and recovery.

24/7 Heart Rate

Learn how your body responds to your daily habits and choices by following your heart rate from morning to night.

Recovery Time

Recovery time tracks the number of easy days you’ve had during the week so you can allow your body to rest and recover.

Activity Goals

Personalize goal types and baseline goal numbers in the Oura App. Activity Goals in Oura are still dynamic, which means that activity goals are increased on high readiness days and decreased on low readiness days.

Workout Heart Rate & Insights

Track your HR during your workouts, and receive post-workout insights that include key HR stats, route, distance, pace, and 
HR recovery.

Activity Levels

Step count, calories burned, inactive times, training frequency, training volume, and more.

Automatic Activity Detection

You no longer need to manually start an activity. Whether you’re running a marathon or running an errand, Oura automatically detects over 30 activities for you and delivers insights afterwards.

Calorie Opt-out

Oura lets you opt out of calories (if desired) so that activity features better fit your lifestyle.

Our results speak for
themselves

At BioRingo, validation is a top priority. The BioRingo has been used in independent studies at UCSF, UC San Diego, MIT Lincoln Laboratory, the US Army, and the US Navy – with more already in the works.

A research team at UCSF has published early results from a large-scale COVID-19 study, TemPredict, revealing that the temperature sensor of the BioRingo could be an effective tool for fever monitoring and early illness detection.

University of California, San Diego is using the BioRingo to look for patterns in heart rate, heart rate variability, temperature, respiratory rate, and sleep that may help identify the onset of pregnancy and/or help predict different pregnancy outcomes and progressions

A team of researchers at West Virginia University published a new study on how accurate consumer tools are at measuring heart rate and heart rate variability (HRV). BioRingo’s infrared photoplethysmogram (PPG) sensor matched performance with clinical-grade ECG and consistently outperformed other PPG tools.
