"Turns out most of the compression garments I've been wearing for years don't actually help my Flow much. Only my abdominal and full length compression make a measurable difference, so those are the only ones I'll be wrestling on moving forward, thanks Lumia!"

Breakthrough Science,
Built For Everyday Life
Wrapped in soft silicone, Lumia fits snugly in your ear’s upper nook like an earbud - designed for all-day comfort and multi-day battery life.
Compatible with most hearing aids, headphones, earbuds, earrings, glasses, and other devices that go in and around your ear.
Less than 1 gram, Lumia is virtually weightless so it blends seamlessly into your lifestyle. Meet the world's smallest wearable.
Discreet and durable, Lumia is there with you through social events, showers, sleep, and more — hard at work in the background.
Lumia charges with light while in your ear—sunlight, indoor lighting, you can even use your phone’s flashlight. Stay charged on the go with the micro solar panel.
The Lumia Initiation Kit comes with a Light Station that fast charges your Lumia with infrared LED lights. A full charge takes about 3-4 hours.
If you need to, drop Lumia into the included keychain Carry Case. The Carry Case's magnifying lens helps Lumia harvest more ambient light.
Your Flow changes through the day, influenced by hundreds of factors. Tag moments in the Lumia app - meals, meds, activities - to learn what's helping and what's hurting.
Tag Events Quickly and Easily
With hundreds of event tags designed for you, easily conduct side-by-side comparison tests to see what works best to get your Flow up!
Lumia normally measures every 5 minutes, but when episodes hit fast, you need more. The new Live Mode feature lets you activate rapid monitoring for hours of real-time, second-by-second data.
Conduct high-fidelity tests to test what works in real-time. If you cross your legs 3 times in a row and your Flow rises each time, you've proven cross-legged increases your Flow.
Capture in high resolution how your Flow handles intense moments.

“With Live Mode, it’s clear how little things — like showers or cooking — make a huge impact on me. Better yet, I can find ways to make it better.”

FAQs
Lumia™ is designed for adults age 18 or over experiencing chronic symptoms that are made worse by standing, such as dizziness, brain fog, lightheadedness, fatigue, headaches, post-exertional malaise, and fainting. These are common in people with POTS, Syncope, Orthostatic Hypotension, Orthostatic Intolerance, Dysautonomia, as well as ME/CFS and Long Covid.
In these conditions, science has shown that blood flow to the brain drops during standing or sometimes even just sitting upright.
The Lumia™ Program is designed to help people with these chronic blood flow disorders better self-manage their conditions, using an advanced wearable worn in the ear combined with the Lumia Edge Access Program.
The Lumia™ wearable is worn only in the left ear, and is designed to be compatible with most, but not all, hearing devices and earbuds.
If you require the use of specific left ear devices, and aren't sure based on looking at photos of how Lumia sits in the ear, feel free to contact us with a photo of what you want to wear at the same time as Lumia.
Lumia™ does the basics like heart rate, but it also does something that no other smart ring or wearable band can do: track drops in blood flow to your head.
Technology like this has never existed before. To this day, only a handful of specialized autonomic labs equipped with Transcranial Doppler Ultrasound can measure drops in blood flow to your head during standing. Lumia™ is the only wearable that tracks head blood flow, which is particularly useful for self-managing chronic conditions where poor blood flow causes symptoms.
Yes, you will need an iPhone capable of running iOS16 or later, in order to support Bluetooth 5. At this time, the Lumia™ program is not available for Android devices although we plan to begin Android development this year.
We are bringing a new-to-the-world technology directly into the hands (and ears!) of the people who need it most, and the best way to get this working reliably for you is by first launching Lumia™ in the tightly streamlined environment Apple enables, where the hardware and software of the devices all speak the same language.
If you do not already have an iPhone, we recommend checking for affordable refurbished iPhones, as excellent compatible models are available starting at just $100, such as a used iPhone SE 2 or iPhone 11.
At this time, Lumia™ is not a FDA approved medical device, and cannot be used to diagnose or treat any medical condition.
Instead, the Lumia™ program is intended for general wellness use to help people with orthostatic conditions better self-manage their symptoms. It is designed to comply with the FDA General Wellness Guidance and Device Software Functions and Mobile Medical Applications Guidance.
This path allows us to bring Lumia™ directly to you to start helping now.
Meanwhile, we are simultaneously conducting the clinical research for Lumia to one day become a FDA-approved medical device and be included in health insurance reimbursement programs.
At this time, the Lumia™ program is launching for residents of the fifty United States.
We would love to expand globally in the future to serve more people who need Lumia™, but are not ready yet.
Some limited international availability may begin in late 2025 - join our email newsletter list to hear when/where we expand next.
Yes! Lumia™ has been approved by the IRS board that governs HSA and FSA programs.
At this time we cannot directly accept HSA or FSA cards at checkout.
Please contact your plan administrator to find out what the process is for seeking reimbursement, if the Lumia™ program is eligible under your specific plan's guidelines, and whether you need to fulfill any other requirements.
No, Lumia™ is designed for people who experience chronic symptoms made worse by standing. The app and data experiences are designed to help people self-manage chronic conditions, and are not designed to be useful to people who do not experience chronic symptoms related to blood flow issues.
Yes, Lumia's Edge Access Program is required for Lumia™ to work. A Lumia™ wearable will not collect new information without an active Program membership. Lumia is both a wearable and a companion iPhone app that work together to help people with complex medical conditions self-manage their symptoms.
If your Program membership goes inactive, you will be able to view your historical information, but the wearable will not collect and process new data.
The Lumia™ Edge Access Program includes:
Mobile App Access. The Edge Access Program supports unlimited data in the mobile app. Lumia's algorithms and secure data servers run in the Cloud - the Program covers the monthly server fees required to run the increasingly advanced data engine.
Free Hardware Upgrades (yes, really). Always stay on the latest and greatest - get Lumia 2 when it comes out at no extra cost.*
Continuous Feature Updates. New features every month to make Lumia even more useful.
Subsidized Replacements. Replace a lost or damaged earpiece for only $99.
Lifetime Warranty. Lifetime coverage for replacements if your Lumia starts not working as well as it should, hassle-free.
Masterclass Content Programming. Learn strategies from medical and patient experts to help you self-manage chronic symptoms.
*next generation shipped if at least 6 months of membership remain
