It records sleep, activity, readiness, heart rate, HRV, stress, recovery and dozens of other metrics, then presents them through Luna’s iOS and Android app. The latest dated review lists the band at £129 or $149, sold through Luna’s official store.
What is the Luna Band?
Luna Band is a screenless wrist tracker designed for continuous health, sleep and exercise monitoring. Its official specification lists more than 70 health and wellness metrics, including sleep, activity, readiness, heart rate, heart-rate variability (HRV), stress and recovery. AI insights and coaching are included without an additional charge.
The band works with iOS and Android and can connect with Apple Health, Google Fit and Clue. GPS is supplied through the phone app rather than built into the band, so route tracking requires carrying a compatible smartphone.

Does Luna Band require a subscription?
No. Luna’s product page explicitly states that a subscription is not required and that AI insights and coaching are included with no additional charges. That makes the band fundamentally different from subscription-led products such as Whoop, where ongoing access to the analytics platform is tied to a membership plan.
What does Luna Band track?
The official specification claims 60-plus sports and workout modes, automatic detection for running, walking, cycling, elliptical training and rowing, plus VO₂ max, training load or effort, heart-rate zones and daily steps.
LifeOS coaching and logging
Gadgets360 reported that Luna’s LifeOS adds voice-based logging for activities and food, a persistent “Ask Luna anything about your health” input, third-party integrations and cause-and-effect insights. The report described LifeOS as free with the band and said rollout was invite-only, with shipments expected from late July 2026.

Feature maturity is important: Tech Advisor’s September 28, 2026 review found that some data and apps were still marked as coming soon, and SpO₂ readings were not yet visible in the app during testing. Those observations describe the reviewer’s software version and should not be treated as a permanent limitation or a universal accuracy verdict.

Tech Advisor’s September 28, 2026 review lists Luna Band at £129 in the UK and $149 in the US, with no hidden charges or subscription. At the time of that review, it was available through Luna’s official store and nowhere else.
Luna claims up to 10 days of typical battery life and a full charge in 60 minutes. Tech Advisor reported roughly a week of 24/7 use and a charge just short of an hour. Actual endurance will vary with recording settings and use. The proprietary charger is included.

How Luna Band compares with Whoop
The central difference is ownership cost: Luna is a one-time hardware purchase, while Whoop requires an annual membership for its analytics and coaching platform. The products also differ in hardware, ecosystem and feature maturity.
| Category | Luna Band | WHOOP 5.0/MG |
|---|---|---|
| Subscription | No required subscription; AI insights and coaching included | US annual plans listed at $199 (Whoop One), $239 (Whoop Peak) and $359 (Whoop Life) |
| Upfront price | £129/$149 in Tech Advisor’s September 28, 2026 review | Plan pricing is membership-based; the cited release does not state a comparable standalone hardware price |
| Advertised battery | Up to 10 days | Up to 14 days for WHOOP 5.0/MG |
| Form factor | Screenless wrist band, 24 g, interchangeable nylon strap | Screenless wearable with a subscription-backed ecosystem |
| Exercise support | 60-plus modes; automatic run, walk, cycle, elliptical and row detection | 145-plus supported activities |
| Notable health features | Heart rate, HRV, stress, recovery, skin temperature, SpO₂ and VO₂ max listed by Luna | WHOOP MG adds ECG, with blood-pressure insights and women’s hormonal insights listed in WHOOP’s May 8, 2025 release |
| Phone and platform support | iOS and Android; Apple Health, Google Fit and Clue integrations | Subscription-backed WHOOP app and ecosystem |
WHOOP’s longer advertised battery life, broader activity count and more established analytics ecosystem may matter to serious training users. WHOOP MG’s ECG is another differentiator. Luna’s advantages are the lower one-time cost, no recurring fee and conventional wrist-band format.

Tech Advisor praised Luna Band’s price, subscription-free model, companion app, sleep tracking and heart-rate tracking. In comparative wear, the reviewer found sleep duration and sleep-stage results broadly similar to Oura, while resting-heart-rate tracking generally mirrored Garmin and Oura.

The same review found that resting and average heart-rate readings generally skewed higher, distance totals differed from other devices, the buckle scuffed quickly and the styling was less polished than some rivals. These are observations from one review, not a claim that Luna is universally inaccurate or unsuitable for training.
Who should buy Luna Band?
It makes sense if you want
- Continuous sleep, recovery and activity data without a recurring bill
- A lightweight, screenless wrist wearable
- iPhone or Android compatibility and integrations with major health platforms
- Basic automatic workout detection plus broader wellness metrics in one app
Consider alternatives if you need
- A built-in display or onboard GPS
- Fully mature software with every promised metric already visible
- ECG or the deeper subscription analytics offered by WHOOP MG
- Confidence based on extensive independent accuracy testing rather than an early review
Where can you buy Luna Band?
As of Tech Advisor’s September 28, 2026 review, Luna Band was sold through Luna’s official store and was not available elsewhere. Availability can change, particularly while LifeOS features are rolling out, so check the official store for current regional stock, delivery terms and strap options.
The Bottom Line
Luna Band is the clearest subscription-free alternative to Whoop for buyers who want sleep, recovery and workout tracking at a one-time £129/$149 price. Its main compromises are early software maturity, phone-dependent GPS and less extensive independent testing than established rivals.
