Why Voltra air?
Voltra gives you a complete picture of your health, tells you how to improve it, and never charges you a penny per month to access your own data.
Optimise your sleep
Not all sleep is equal. Voltra measures every stage - light, deep, REM and wake - and shows you exactly what's happening during the hours you're unconscious. Understand what's affecting your recovery, fix what's holding you back and wake up feeling the difference.
Member Spotlight
“One of the biggest insights Voltra has given me is understanding what true rest feels like. Tracking my sleep has shown me when my body really recovers — and those insights help me make small changes that lead to better mornings and sharper focus.”
— Alexa P.
Connect with your heart health
Continuous readings show how your blood pressure shifts through the day - no cuffs, no interruptions, just steady awareness on the go.
Member Spotlight
“Seeing how my blood pressure shifts throughout the day has been incredibly eye-opening. I don’t have to stop what I’m doing or use a cuff - Voltra just gives me steady awareness in the background. It’s helped me feel more informed and in control of my health.”
— Alexis P.
Measure the impact of every step & rep
View total steps, distance, calories, and time in heart-rate zones across 30+ sport modes - giving you a clear record of effort, not rough estimates.

Assess your recovery
Voltra analyses how your body responds to your workouts, sleep quality, stress and menstrual cycle - so you finally understand what's actually affecting your recovery, and can adapt your effort before fatigue sets in.
Member Spotlight
“Being able to see my stress across four clear levels helps me understand my daily habits better. It’s made it easier to manage my energy and reset before stress builds up.”
— Daniel K.
Analyse your resilience
Voltra's 24/7 HRV monitoring shows how your body responds to stress and recovery, helping you decide when to push, when to pause, and spot burnout before it hits.
Member Spotlight
“Having 24/7 HRV monitoring has changed how I manage my energy. I can see how my body responds to stress and recovery, which helps me know when to push and when to pause before burnout sets in.”
— Michael O.
Daily blood insights
Your blood data tells a story about your body that most people never get to read. Voltra brings that data to your wrist - tracking how your blood oxygen influences your physical, mental and emotional wellbeing every single day. No clinic required. No subscription. Just your health data, yours to keep.
Member Spotlight
"I never thought to check my blood oxygen until Voltra flagged it was dropping during the night. Within a week of making changes to my sleep position I was waking up with more energy than I'd had in years."
— James R.
Understand your unique cycle
Voltra tracks your menstrual cycle alongside your health data, helping you anticipate changes in energy, mood and performance before they happen. Understand your natural rhythm and adapt your training, recovery and daily routine around it - not against it.
Member Spotlight
“Voltra helped me understand what real rest feels like throughout my cycle. By tracking my sleep, I can see how my body recovers differently during each phase of my menstrual cycle and those insights help me make small adjustments that improve my energy, mood, and mental clarity, especially around my period.”
— Jenifer D.

What our customers say
I purchased one of these trackers the other week, and it's been a life saver. I have quite a complex autoimmune disease and was advised to get some sort of tracker. So glad i did as the doctors messed up some of my medication. They shouldnt of been prescribed together as it causes arrhythmia and possible cardic arrest. The tracker picked up the erratic bp and pulse and i was taken to hospital quickly. If i carried on with the medication who knows what would of happened 🙈
Its a great device. It help me to know about my body. Thanks Voltra for creating such a best device.
Ordered the health band from the website, but because I live in Thailand, I got in touch with customer services to find out the cost of delivery. Within a few days I received a confirmed price for the band and the shipping costs. It was tracked by the post office, and updated regularly. Took 4 days to arrive.
Absolutely delighted with my Voltra
Absolutely delighted with my Voltra health band. Gives me a real insight into my general health, sleep, and activity. My partner has a much more expensive health band (a different brand), and honestly the Voltra does everything just as well. I highly recommend this very competitively priced band.
Love it
Love it. It really easy to charge and the battery last ages
Excellent product and so easy to set up…
Excellent product and so easy to set up download the app! First class customer service and super fast delivery well done guys!
Been using my fitness tracker for 6…
Been using my fitness tracker for 6 weeks now and wouldn’t turn back. I was paying £200 a year for my old one and the voltra does all the exact same things and more
I was waiting for some kind of catch
I was waiting for some kind of catch, but this does exactly what it says on the tin. The biggest thing for me was the battery life and it’s genuinely amazing sometimes lasts even longer than the 40 days. Can’t fault it for the price at all

VOLTRA | The biometric health band that understands your body better than you do
Simple to use and set up.No problems sending data to my i-phone overall very pleased.
Volt tracker
Great devise, mostly accurate, but blood pressure readings are low compared to a manometer reading
Great productand company
A great improvement over tracker's with a screen
Its ok, blood pressure reading are done on the hour every hour. I would have preferred real time or every 10 minute. Slightly disappointed that it doesn't track body temperature, (body basal temperature) However I have Worn it on my leg and worked just as well. I have recommended it to others too.
Great tracker, amazing battery life and does so much. Link to Apple health is a bonus!
Volt Tracker
Head measuring unit very good seems reasonable accurate as a guide. Battery life is long not yet recharged after everyday use. Only let down are supplied straps not always big enough, change for a suitable nato style nylon woven strap, more comfortable and secure.
A good, value for money option...
A good, value for money option for a step tracker. I like the option to monitor sleep and steps. Comparitive tests were carried out at regular intervals during the week. Not a product I rely on for accuracy, but easy to set up and comfortable to wear.
Brillant product, easy to use
Brillant product, easy to use Pity it didn’t use a usb-c charging cable, but the one supplied is easy to use The data seems to be accurate, pity the blood pressure reading don’t synch to apple. Future Design update. A second holder for the strap.
Quick
Unfortunately, the one I bought died on day...
Unfortunately, the one I bought died on day one after a firmware update, VOLTRA did reply to my help requests and offer to replace it, but this was sadly after I went to PayPal to claim my money back. Soo, I can't give a fair evaluation on the product as I've never used it, the company however do appear to be keen to help.
Good
Good experience . Kept me updated all along the way via email
ordered arrived a day late but was nicely packed.
Still waiting on delivery it’s almost 1 month EDIT - Voltra responded and sorted fast, can't update star rating
Battery
Was working just for 2 day. Battery issues
My biggest disappointment is that the device makes clear that it is not able to give you readings from which you can make top level medical assessments

Couldn't get it to work

Frequently Asked Questions
-
Really. No monthly fee, no annual renewal, no premium tier you need to unlock to see your own data.
You pay once for Voltra and every single feature is yours forever from day one. No small print. No surprises.
-
Voltra Air uses the same optical sensor technology found in premium wearables. Our blood pressure readings have been independently compared against cuff readings with consistently closer than other wearables on the market.
As with any wrist-worn tracker, accuracy is best achieved by wearing the band snugly and consistently - particularly overnight for sleep and HRV data. -
Up to 40 days on a single charge. You won't be taking Voltra off to charge it every night like a smartwatch - most users charge it once every few weeks and forget about it in between.
-
WHOOP charges up to £239 a year in subscription fees on top of the device cost. Voltra Air costs £39.99. Once. That's it. Over three years, switching to Voltra saves you the equivalent of nearly £700 in subscription fees - for the same quality health data with no ongoing commitment.
