Why Voltra?
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.

FAQs
Is there really no monthly subscription?
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.
How accurate is the data?
Voltra 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.
How long does the battery last?
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.
How does Voltra compare to WHOOP?
WHOOP charges up to £239 a year in subscription fees on top of the device cost. Voltra 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.
Who is Voltra for?
Voltra is designed to work for everyone. Whether you're a fitness enthusiast chasing personal bests, someone looking to get a better handle on their health, or you simply want to understand your sleep, stress, and body better - Voltra was built for you.
No experience needed, just a desire to know more about yourself.
Is Voltra waterproof?
Yes - Voltra is IP68 rated which means it's fully waterproof. Wear it in the shower, the pool, the sea or the gym without any concern. You never need to take it off.
What if I change my mind?
You have 30 days to change your mind. If Voltra doesn't exceed your expectations, send it back and we will refund you, no questions asked.
