Quick Answer
You can buy one now. That is the headline change since we first wrote this up. The Luna Band spent July and August 2026 in an invite-only phase, and at IFA 2026 Luna announced that regular worldwide shipping had started. It costs $149 in the US, with Luna stating that figure includes taxes and delivery, and EUR 149 in the EU, sold direct from lunazone.com. There is no subscription: the LifeOS coaching that is the whole point of the device is included, which is the single cleanest thing about it next to WHOOP. Luna says the waitlist that preceded shipping passed 100,000 people.
Now the catch, in three parts, and they are all things the marketing does not lead with. First, this is a deliberately stripped device: no screen and no GPS, so run routes come from your phone, and 24 grams on your wrist gives you nothing to look at. Second, the hands-free voice feature that gives the band its identity is documented against Apple Siri, and the band itself has no microphone, so voice runs through your phone or earbuds. Luna's spec sheet confirms the app works on iOS and Android, but there is no published Android assistant equivalent, which makes the headline feature an iPhone story today. Third, it is still new. Luna's own spec sheet claims 70-plus metrics from a wrist optical sensor, and nobody has published an independent accuracy comparison against a chest strap or a sleep lab yet. Buy it for the price and the no-fee promise, not because the numbers are proven.
What Changed Since the Launch
The timeline matters if you were watching this device earlier in 2026 and gave up. Luna opened pre-orders on July 4, 2026 and scheduled a first shipment for July 31 that went out invite-only. That is where a lot of the coverage, including our first version of this page, stopped. The IFA 2026 announcement on September 4 is the part that changed the buying decision: general worldwide availability, at the same $149. Luna's store lists the band in Onyx Black, Aloe Green and Desert Beige (checked September 14, 2026).
If you read anything that still describes the Luna Band as waitlist-only or invite-only, it predates that announcement.
Verified Specs
These come from Luna's own product page and spec sheet rather than from press summaries, because the interesting details of a screenless tracker are the boring ones.

The two rows worth pausing on are battery and water resistance. Ten days between charges with a one-hour top-up is the practical argument for a screenless band: it stays on your body, including overnight, which is when the metrics that matter get collected. And 5 ATM means you can keep it on in the shower and the pool, which a device that has to be worn continuously to be useful actually needs.
What It Tracks
Luna groups its output into Sleep, Activity and Readiness and claims more than 70 metrics in total. The measured inputs are heart rate and heart rate variability, blood oxygen, skin temperature, and motion, with sleep, stress and recovery derived from those. On the training side the spec sheet lists VO2 max, training load, heart rate zones and daily steps.
LifeOS is the layer on top, and it is what Luna is really selling. Rather than a fixed dashboard, it builds a daily plan from your readings, and Luna describes it as re-training its models around your body when you set a new goal. The app also ships what Luna calls Micro Apps for specific jobs: caffeine timing, hydration, jet lag, fitness age and circadian rhythm.
Be clear-eyed about the claim structure here. Seventy metrics from four sensor types means most of those numbers are derived, not measured. That is true of every recovery wearable, Luna included, and it is why an independent accuracy review is the thing this device still needs.
The Voice Part, and Which Phone You Need
Luna's pitch since CES 2026 has been hands-free, voice-led interaction: log a meal, note a symptom, record how you are feeling, or ask LifeOS for guidance, all without opening the app. Luna describes voice commands as working through a connected device or earbuds, and the assistant integration it names is Apple Siri.
So the honest answer to "does the voice thing work on my phone" is: the documented hands-free path is Siri on an iPhone. The Luna app itself is on both iOS and Android per Luna's spec sheet, and the App Store listing describes an in-app voice mode and a chat interface for LifeOS alongside it, so Android owners are not locked out of the band or the coaching. They are relying on the app rather than on a hands-free assistant. If talking to your tracker without touching your phone is the reason you want this, that is currently an iPhone feature.
One more grounding detail: the companion app sits at 4.0 stars across roughly 180 App Store ratings as of early September 2026, on version 2.0.2. That is a small sample for a device with a 100,000-person waitlist, which tells you how early this still is.
Luna Band vs WHOOP vs Fitbit Air
| Feature | Luna Band | WHOOP | Fitbit Air |
|---|---|---|---|
| Subscription | None | Required | Optional Premium |
| Screen | None | None | None |
| Standout | Voice-led LifeOS at a flat $149 | Deep recovery, long validation record | Price plus Google ecosystem |
| Maturity | Shipping since September 2026, unproven | Established | New but backed by Google |
The comparison people actually want is against WHOOP, and it turns on one question: is a subscription-free coach that nobody has independently validated worth more to you than a validated recovery loop you rent forever. We work through that trade in detail in Luna Band vs WHOOP, and the Google-shaped version of the question in Luna Band vs Fitbit Air.
Who Should Buy It, and Who Should Wait
Buy it if you want continuous recovery and sleep data, you are done paying monthly for it, and you can accept that the accuracy story is still open. At $149 with a ten-day battery and no ongoing fee, the total cost of ownership argument is genuinely strong, and it is stronger for iPhone owners who get the hands-free path.
Wait if you need proven accuracy for training decisions, if you want GPS on your wrist, or if you are on Android and the voice feature was the draw. Wait too if you want to see a long-term review; Luna has been shipping to the general public for days, not months, and the useful reviews of a recovery wearable are the ones written after a few sleep cycles and a few software updates.
Where Beacon Fits
Here is the plumbing answer, because with a screenless band it decides whether the device is useful to you. Luna's spec sheet lists Apple Health, Google Fit and Clue as its integrations, and its app listing also references Health Connect. Beacon reads from Apple Health, and those are the platforms the Luna Band would have to share through, so on iPhone the path from the Luna Band into your wider health picture is clear. Beacon has no Android version, so on Android there is no path from the Luna Band into Beacon. We have not verified the iPhone path with a Luna Band ourselves, so confirm in the Luna app that your data lands in Apple Health before you count on it.
The wider point is that the Luna Band is one device making one bet. Beacon works across the wearables you already own on iPhone, and gives you voice coaching, nutrition and recovery in one place today, without asking you to trust a single new sensor. If you are shopping the category rather than this one product, read the best screenless fitness trackers of 2026, and which wearable metrics actually sync to Apple Health for the question that decides most of these purchases.
FAQ
Can you buy the Luna Band yet?
Yes. Luna announced at IFA 2026 in September that regular worldwide shipping had started, ending the invite-only phase that followed pre-orders on July 4 and a first shipment on July 31, 2026. It is sold direct from lunazone.com. Any coverage describing it as waitlist-only predates that announcement.
How much does the Luna Band cost?
$149 in the US, which Luna states includes taxes and delivery, and EUR 149 in the EU. There is no subscription, so that is the whole price. LifeOS coaching and AI insights are included at no additional charge.
Does the Luna Band require a subscription?
No. Luna's spec sheet lists AI insights and coaching as included with no additional charges, and the companion app is free. That is the main structural difference from WHOOP, where the recovery platform is rented monthly.
What is the Luna Band battery life?
Luna rates it at up to 10 days, with a full charge taking about 60 minutes using the included charger. The band carries a 5 ATM water resistance rating and weighs 24 grams, so it is designed to stay on through showers, swims and sleep.
What does the Luna Band track?
It measures heart rate and HRV through a multi-LED optical sensor, blood oxygen, skin temperature, and motion through a 6-axis IMU. From those inputs Luna derives sleep, stress and recovery, and reports more than 70 metrics grouped into Sleep, Activity and Readiness, including VO2 max, training load, heart rate zones and steps. There are more than 60 sports modes, with automatic detection for a few. There is no screen and no GPS, so routes come from your phone.
Does the Luna Band work with Android?
The band and the app work on Android; Luna's spec sheet lists both iOS and Android. The caveat is the hands-free voice feature. The assistant integration Luna documents is Apple Siri, and the band has no microphone of its own, so voice runs through your phone or earbuds. There is no published Android assistant equivalent, which makes fully hands-free logging an iPhone feature today. Android owners use the app's own voice and chat modes instead.
Is the Luna Band better than WHOOP?
It is cheaper and has no subscription, and it has a ten-day battery. What it does not have is a validation record. Luna has been shipping to the general public since September 2026, and no independent accuracy comparison against a chest strap or a sleep lab has been published. WHOOP has years of that behind it. If you need numbers you can make training decisions on, that gap is the whole answer.
