Sleep is crucial for our well-being, but current sleep trackers often miss the mark. Many devices use basic sensors like heart rate and accelerometers, giving only a basic idea of sleep quality. Troubled by these limitations, our experienced team, with 10 years in EEG analysis, aimed to create an ideal solution for nighttime tracking.

Despite trying different things like sleep masks and soft headbands, comfort remained a challenge until the introduction of the Flowtime Brain Tag. It stands out by using advanced multidimensional sensors, taking sleep monitoring to a new level.

Unlike pricey medical-grade polysomnography (GSP) systems, it ensures comfort by allowing EEG monitoring at home, weighing only 6 grams (0.21oz).

Serving as an innovation, it not only tracks sleep seamlessly but also provides insights into unique sleep indexes like sleep spindles and micro-awakening.

Going beyond monitoring, it empowers users with biofeedback training, including SMR, breathing, and meditation, offering a comprehensive approach to improving mental well-being and overall sleep quality.

The Most Accurate & Powerful Sleep Tracking Wearable

The small science-fiction-level tag boasts 5 advanced sensors, providing a comprehensive assessment of your sleep patterns.

EEG: brainwave sensors made of Titanium, strong but light, highly durable, long-lasting, and no skin allergies.

PPG & SpO2: track the heart rate, and measure the oxygen saturation levels.

Temperature: monitor body temperature fluctuation, providing insights into your sleep cycle and sleep environment.

6-Axis Accelerometer: understanding your movements in three-dimensional space to monitor and analyze sleep positions and patterns.

Why is EEG Data So Important? 

EEG is the Benchmark of Sleep Tracking. Flowtime Brain Tag offers data that is often used in scientific research and clinical settings, providing you with a high level of sleep analysis and monitoring.

Sleep spindles: brief bursts of brain activity with a frequency of around 11-16 Hz, typically lasting for 1-2 seconds. Occur during non-rapid eye movement (NREM) sleep, specifically in Stage 2. Functions include solidifying memories, enhancing learning, and ensuring stable, uninterrupted sleep.

K-complex: a distinctive waveform in non-rapid eye movement (NREM) sleep to keep sleep deep and steady, helping move from Stage 1 to 2.

Delta waves: most prominent in Stage 3 and Stage 4 of non-rapid eye movement (NREM) sleep, also known as slow-wave sleep (SWS), typically ranging from 0.5 to 4 Hz. As a hallmark of deep sleep, it’s essential for physical recovery, immune function, learning, and memory retention.

EEG-Based Sleep Report

Comprehensive Sleep Quality Scoring

Get an advanced sleep score out of 100, covering key aspects like sleep duration, REM, deep sleep, and unique EEG-only metrics like the Spindle Index, offering deeper insights than the standard track. 

By analyzing the quantity and amplitude of sleep spindles, it’s clear whether your ability to have a sound sleep is good or not. If not good enough, try out the SMR training in the app to see if the index gets improved in the long term. If it’s fairly good, and you take a long time to fall asleep, we recommend you try out Breathing Training or Deep Body Scan to relax the body and mind to help you fall asleep.

Insightful Sleep Stage Correlations

A vertically aligned sleep report offers a detailed, intuitive view of how sleep stages correlate with brainwave activity, heart rate, and HRV, enabling you to tailor personal sleep improvement strategies. Typically, heart rate generally decreases while HRV increases, indicating the body’s recovery. 

Studies have shown that alcohol consumption before bedtime tends to reduce the overall duration of slow-wave sleep, even though alcohol may help individuals fall asleep faster. With the Flowtime sleep report, you can easily find out the patterns that different activities may lead to. A healthier lifestyle is on the way.

Test it Out: What Sounds Really Ease You into Sleep Faster?

Flowtime Sleep Library

Experience peaceful nights with Flowtime’s sleep audio: Guided meditations, relaxing sounds, ASMR, and sleep stories, all crafted to help you relax and effortlessly fall asleep.

Stream Anything that Puts You Asleep

Flowtime’s free mode lets you stream your favorite audio to fall asleep. Whether it’s an audiobook or podcast, the audio gently fades away as you drift off, ensuring you never lose your place. If you have a lullaby album on Apple Music or Spotify, just play it and go back to the Flowtime app to record the biodata.

Daytime Brain Training for Better Sleep & Focus.

Flowtime goes beyond insights, equipping you with biofeedback SMR, breathing, attention, relaxation, alpha, and theta training. A comprehensive tool to enhance your mental health and well-being.

Daytime SMR Elevates Sleep & Memory

Numerous studies have shown that daytime SMR training can significantly enhance night-time sleep quality and memory retention.

Hoedlmoser (2008) found that participants fell asleep 45% faster.

Cotoos (2009) found that testers reduced nighttime awakenings by 53%.

SMR Training Real-time Data & Report

Biofeedback SMR training is like a brain gym, giving you real-time feedback and reports to fine-tune your brain’s natural ability to sleep well.

Flowtime Previous Campaign: Meditation Headband

We launched the Flowtime Meditation Headband Campaign in 2018 and successfully fulfilled it.

We listed it on Amazon, and not every Kickstarter campaign can pull off that move! But it’s not the end of the Flowtime Meditation Headband yet. Since 2020, we’ve upgraded the headband four times to improve its performance and updated the app for more features, including new brainwave rhythm trends, audio biofeedback, and raw data export. We listen to your feedback carefully.

Flowtime Team

We are the Flowtime team, engaged in brain science study for years, and are leading the world in technologies like consumer-grade EEG acquisition algorithms that can play an active role in people’s daily lives.

To help more people benefit from meditation and meditate with intuitive biodata, we came up with the idea of the Flowtime headband. This device can monitor brain waves, heart rate, and heart rate variability during meditation and generate detailed reports. The word “flow” can be defined as an “optimal state of consciousness where we feel our best and perform at our best.” Flow refers to those “in the zone” moments where the focus gets so intense that everything else disappears. 

Now, we bring the idea of “flow” into sleep, hoping you achieve a restful and undisturbed night’s rest.

Development & Research

We’ve explored various forms

We launched the smart sleep mask campaign in 2018 and have more than 800+ backers. Now we are coming back with a better product form.

We also considered a soft headband, but it failed to capture consistent signals throughout the night, especially as we turned over during sleep.

Inspiration for Brain Tag

Inspired by science films, like the mind-reading devices in Swan Song, the concept of Brain Tag was born.

We’ve had a functional prototype to ensure that the concept works, and we are dedicated to improving the performance in the coming month to ensure mass production goes well.

Our engineers are doing concept proof and functional testing.

When we first had the sample in our hands, we were also astonished that the tag was so small and invisible!
