What our customers say
For a relatively cheap tracker this is pretty good. You can either view the data in it’s own app or, it feeds through into Apple Health. Quite impressed with Voltra’s customer service too. I noticed that they’ve just released a new version - Voltra Pro. I contacted customer services and they have agreed to exchange my current tracker for the new model - just pay the difference and, they’re organising return shipping for the original item. Impressed so far
Excellent product and information it provides
I've been looking for a health tracker for quite some time, doing lots of research and fors and against. The voltra ticked alot of boxes with a one time purchase and your data is there for you always. It's been a game changer for me, i have been able to see what needs improving and lots of metrics to feed back to my Dr. The battery life is amazing only changing on the day I received it and it's still going strong 14 days later. The hrv and blood pressure are really useful insights as well as the the sleep data. Overall a really affordable, light weight stylish health tracker. Keep up the good work.
Very good
Not having to think about taking my blood pressure has actually improved my readings. Pressure shows a marked improvement.
Really impressed, just a minor niggle
I've been wearing the Voltra Pro for three weeks now and overall I'm impressed. The sleep tracking is accurate and the heart rate monitoring has been consistent with readings I've taken manually. My only gripe is that the strap feels slightly stiff at first. Once it softened up it's been comfortable 24/7. For the price and no subscription I think it's excellent value.
Great tracker, app needs a bit of work
The hardware itself is fantastic - solid build, comfortable to wear and the battery life has been outstanding. I'm on day 28 and still at 30%. The blood pressure readings are a useful guide though I wouldn't rely on them clinically. Dropping one star because the app interface isn't as intuitive as I'd like, but then again i'm comparing it to ones 3 or 4 times the price. Still, for £99.99 with no monthly cost this is a no-brainer.
Solid Device
First few days the sleep data seemed off but after about a week it settled into something that felt accurate. My recovery scores now match how I actually feel which is what I wanted. The step counting is spot on and I love that I can see my HRV trends over time. Would be five stars if the initial setup was smoother. Customer service were helpful when I reached out which I appreciated.
The tracking capabilities on this are genuinely impressive for the price point. Sleep, stress, heart rate all working well and the data gives me useful insights into my training. The strap is my main issue - i've got huge wrists but I just wish they sold a slightly bigger one, even if it came separately. It hasn't come off but it makes me slightly nervous during exercise. Everything else though is excellent and the no subscription model is exactly what I was looking for.
Happy with it overall, a few teething issues
I switched from a branded tracker that was costing me £25 a month and I don't regret it so far. The Voltra Pro tracks everything I need and the accuracy is good. Had a small issue with the device not connecting after an update but a restart fixed it. The heart rate monitoring during workouts seems reliable and the sleep breakdown each morning is detailed. Would recommend to anyone wanting a capable tracker without the subscription drain.
Decent but not quite what I expected
There's a lot to like - the battery life is great and the no subscription promise is what drew me in. However I've found the blood pressure readings to be inconsistent at times compared to my NHS cuff monitor. Some days they're close, other days they're a bit off. In Voltra's defence, they are open about this being a trend monitor rather than relying on it for medically accurate BP readings - so for that i'd say it's great The sleep tracking seems good too. It's perfect for general wellness/awareness
When the new app comes, this will be the best out there
I wanted to love this and in a lot of ways I do. The step counting is just as accurate as my apple watch, the battery is impressive and not paying a subscription is refreshing. But the app feels basic in some places. I did reach out to Voltra and they told me there is a new app on the way very soon which I'm looking forward too as I truly don't think anything will compare if they update the app slightly The app definitely isn't a deal breaker though, it serves it's purpose. I wouldn't let it put you off buying one
Took a while to arrive - Royal Mail issues
Dropping two stars purely because of the delivery. I ordered and then heard nothing for nearly two weeks. Started to think it had been lost. They did supply a tracking number and I understand that it was Royal Mail's fault rather than the company itself but it was frustrating not knowing what was happening. That said, the tracker itself has been amazing since I got it a week ago. I've since ordered a normal Voltra for my husband and shipping was much faster, around 2 days.

Never. You pay £99.99 once and that's it. No monthly fees, no annual renewals, no premium tiers. Every feature, every metric, every update is included for life. We built Voltra because we were tired of paying £30 a month just to access our own health data. That will never be us.

The Voltra Pro uses a 6-sensor optical array that delivers clinical-grade readings for heart rate, HRV, blood oxygen and sleep staging.
