Quick verdict
Dodow is a legit, well-liked product from a real company, and it does exactly one thing: it helps you slow your breathing at bedtime. You tap it, it projects a soft blue circle on the ceiling, and you breathe in as the circle grows and out as it shrinks. Over a few minutes it slows you from about 11 breaths a minute to about 6, then shuts itself off after 8 or 20 minutes. No screen, no app, no subscription.
The honest part: slow breathing at that pace has real research behind it, but we found no published study of the Dodow device itself, and two of the four scientific papers its product page cites could not be found on PubMed. Think of it as a $60 pacing tool for a free technique. If counting breaths in the dark keeps you awake, it can be worth it. If you already use a breathing app or watch, you may not need it.
Pros
- ✓ Simple and screen-free: no app, no phone, no subscription
- ✓ Based on slow breathing (about 6 breaths a minute), which has research support for relaxation
- ✓ Turns itself off after 8 or 20 minutes and makes no noise
- ✓ Long 100-day return window plus a 2-year warranty
- ✓ Livlab, the maker, has 4.6 stars on Trustpilot from about 4,000 reviews
Cons
- ✗ No clinical study of the Dodow device itself
- ✗ Two of the four studies it cites could not be found
- ✗ You pay return shipping, and original shipping is not refunded
- ✗ Works best lying on your back looking at the ceiling
- ✗ A free breathing exercise or a watch you already own can do the same job

What is Dodow and how does it work?
Dodow is a small, round, battery-powered light made by Livlab, a company founded in Paris in 2012. It is about 3.5 inches across, weighs about 6 ounces, and runs on 3 AAA batteries that come in the box.
- Put it on your nightstand and lie on your back.
- Tap the top once for an 8-minute session, or twice for 20 minutes.
- Watch the blue circle on the ceiling: breathe in as it grows, out as it shrinks.
- The pace slows to about 6 breaths a minute (roughly 4 seconds in, 6 seconds out) within about 2 minutes.
- The light turns off on its own when the session ends.
It has three brightness levels. One hands-on reviewer at Reviewed.com found you can only change the brightness while the device is off, which the instructions did not make clear. Livlab says the light is under 1 lux on the ceiling, too weak to bother a partner whose eyes are closed.
Does Dodow actually work?
Here is what the evidence does and does not show:
- The breathing technique has support. A 2018 review of 15 studies found that breathing under 10 times a minute raises heart rate variability and is linked to relaxation and lower anxiety.
- There is a small sleep study. In a 2015 study of 14 people with insomnia and 14 good sleepers, 20 minutes of slow breathing at about 6 breaths a minute before bed shortened the time it took to fall asleep and cut night awakenings. No device was used, and the study was small.
- The device itself is untested. PubMed and ClinicalTrials.gov show no studies of Dodow. Back in 2017, Digital Trends reported it “hasn’t been clinically validated,” and we found no study since.
- Some citations do not check out. Of the four “scientific references” on the product page, two exist on PubMed. Two (a 2020 Lehrer paper and a 2012 Del Pozo and Gevirtz insomnia paper) could not be found. None of the four tests Dodow.
- Big claims are the company’s own. “Falling asleep up to 2.5 times faster,” “1,000,000 users” and “used in hospitals” come from Livlab, with no published data behind them. The 2.5x figure is based on what users reported.
Bottom line: Dodow is a good way to make slow breathing effortless, because you follow a light instead of counting. Whether that helps you sleep depends on you. Reviewed.com’s tester found it relaxing but did not fall asleep faster. Dodow is not a medical device, and we found no FDA clearance. If you have ongoing insomnia, talk to a doctor.
How much does Dodow cost?
| Option | Price on 2026-10-30 | Notes |
|---|---|---|
| Dodow on the brand store (livlab.care) | $59.90 | Not a sale price; it has cost about $59 to $60 for years |
| 2 Dodows on the partner offer page we link to | $88.50 | Buy 1, get 1 50% off ($44.25 each) |
| 3 Dodows on the partner offer page | $118 | Buy 2, get 1 free ($39.33 each) |
| Brand store add-ons | Travel case $12.90, lifetime warranty $9.90 | Offered on the product page |
Shipping is free on US orders over $45 on the brand store, so one Dodow ships free. The brand page says “tax included,” but its sales terms say US tax is added at payment, so check the total before you pay.
The 100-day guarantee: read the fine print
- Window: 100 days from delivery, for orders from the official store. Start a return through Livlab’s help center with your order number and email.
- Return shipping: “Return fees are generally payable by the customer” unless the item is defective or wrong. Fees for special delivery are not refunded.
- Condition: it must come back in good condition, in the original packaging, with all accessories.
- Mixed messages: the product page says “You have 100 days to test Dodow,” but the general sales terms list 100 days only for another Livlab product and exclude items “clearly used” for hygiene reasons. The refund policy itself does include Dodow. Keep the box and save your emails.
- Real buyer reports: a few Trustpilot reviewers complained about paying return shipping, a return system that could not find their order, and a refund that was cut short before the company fixed it.
- Warranty: 2 years; a lifetime warranty is an optional add-on.
Is Dodow legit, or a scam?
It is legit. LIVLAB SAS was registered in Paris in August 2012 and has sold Dodow for years; its founders are Alexandre Dujoncquoy, Pierre-Luc Deniel and Gui Perrier. Its US address is Livlab Inc. in Plainview, New York, which has an A+ rating with the BBB. That A+ comes with no accreditation, no complaints and no customer reviews, so it says little either way. We found no FTC action, class action or recall, though that is based on web searches.
Livlab calls itself an “independent laboratory,” but its French registration describes its business as developing and marketing products, and we found no Livlab research on PubMed.
What real buyers say
Livlab has 4.6 out of 5 on Trustpilot from 4,069 reviews (68% five-star, under 1% one-star). Two things to know: that score covers all Livlab products, not only Dodow, and only 128 of those reviews are from the last 12 months. Several reviewers also said buyers of another Livlab product were offered free audio content for writing a review.
What buyers like: it calms racing thoughts, it is drug-free, it is simple and silent, and customer service has replaced faulty units quickly.
What buyers complain about: return costs and return hassles, that it simply did not work for them, unclear controls for brightness and turning it off, no low-battery warning, and a price that feels high for a simple light.
How Dodow compares
| Option | Price | What it does |
|---|---|---|
| Dodow | $59.90 one time | Light you breathe along with; 8 or 20 minutes; no app |
| Morphée | $69.99 | Screen-free audio device with guided meditation and relaxation sessions |
| Hatch Restore 3 | $169.99, then $5.99/month for Hatch+ | Sunrise alarm clock with sounds, light and bedtime routines |
| Apple Watch Breathe | Free if you own the watch | Guided breathing with taps on your wrist; adjustable pace |
| 4-7-8 or NHS breathing exercises | Free | Count your own breaths; no device needed |
Dodow’s real advantage over the free options is that you do not have to count or look at a screen. If that matters to you, it is reasonably priced. If not, try a free breathing exercise for a week first.
Who should buy it, and who should skip it
A good fit if: your mind races at bedtime, you sleep on your back, you want something screen-free with no subscription, and you like the idea of a drug-free routine.
Skip it if: you mostly sleep on your side or stomach, you already have a breathing app or smartwatch you would actually use, you have a breathing condition such as asthma that makes slow paced breathing hard, or you need treatment for chronic insomnia (see a doctor).

FAQ
Does Dodow really work?
It helps you breathe slowly, about 6 breaths a minute, which research links to relaxation and, in one small study, to falling asleep faster. The Dodow device itself has never been tested in a published study, so results vary from person to person.
Has Dodow been clinically tested?
Not that we could find. PubMed and ClinicalTrials.gov list no Dodow studies as of 2026-10-30.
How much does Dodow cost?
$59.90 on the brand store on 2026-10-30. The partner offer we link to sold 2 for $88.50 and 3 for $118.
What is the Dodow return policy?
100 days from delivery for official-store orders. You usually pay return shipping, original shipping is not refunded, and it must come back in its original packaging with all accessories.
What is the difference between the 8 and 20 minute modes?
Tap once for 8 minutes or twice for 20 minutes. The light turns off by itself when the session ends.
Will the blue light keep me or my partner awake?
Livlab says the light is under 1 lux on the ceiling, too weak to disturb a partner whose eyes are closed. That has not been independently measured.
Does Dodow work if I sleep on my side?
It works best lying on your back looking at the ceiling. Side and stomach sleepers may find it less useful.

No. It is sold as a sleep aid, not a medical device, and we found no FDA clearance.

Livlab, a company registered in Paris in 2012, with a US address in Plainview, New York.
