Product Description
Product Description
Your state of mind affects how you breathe. But how you breathe can also change your state of mind. Studies have shown how slow, deep and consistent breathing can lower blood pressure, reduce stress and increase the flow of endorphins in your blood stream. While unobtrusively clipped to your pants or bra, Spire senses your breathing patterns throughout the day. When you're tense or stressed, a gentle notification reminds you to stop and take a breath, while the included smartphone app guides you in short, simple exercises to increase your calm and focus. The stone side of the Spire tracker must be positioned against your body in a way such it can detect your torso's expansion and contraction as you breathe

An Incredibly Valuable Tool - Highly Recommended!
Top reviews from the United States
There was a problem filtering reviews. Please reload the page.
- Reviewed in the United States on November 3, 2015Style: IndividualVerified PurchaseI've been using Spire for about 3 weeks now and I've been debating about how to review it. I've decided to give the product 5 stars. If I could, I'd give it 4.5 but that's not an option, and I genuinely believe it deserves more than 4 stars. I won't describe what the product does, if you're reading this then presumably you already know that and you're trying to figure out if it actually delivers. I'll list what I really like about the product, and what I want to see change.
Positives:
- getting real-time notifications when I'm not breathing properly is simply huge. I was just on a phone meeting and got a notification on my iPhone that it had been awhile since I'd taken a deep breath. Sure enough, Spire was right. It was just a nice little nudge, a reminder, to get back to doing what I know is important, full and functional breathing.
- being able to track through my day when I was calm, when I was in focus, when I was tense, it's really helpful information. Spire can do better on this count and I'll talk about that in a moment. The data presentation and tracking is not as dialed in as I'd like it to be, but is it better than what I was doing pre-Spire (which was, namely, nothing)? Oh heck yeah.
- alerts are great. You set them up within their parameters and now the app gives you real time feedback. If I've been tense for 3 minutes, Spire will tell me. If I've been in an extended period of calm or focus, I'm going to see that, too. And that's helpful for determining what I was doing/thinking/focusing on to create that state.
- the boosts. Those are recordings you can listen to in order to increase a sense of calm, or focus, increase energy, etc... It's a nice library of resources. And they have a nice 'foundation pack' teaching you some elemental breathing techniques along with getting to know your device and the app.
- last but not least, I like having such a modest device to track my steps. I don't wear a pedometer, I don't wear a fitness watch, so it's nice to have Spire do this for me.
- some of the problems others have noted have not been a problem for me at all. I wear it on my waistband and initially thought it would bug me. And it did bug me, absolutely. For about 45 minutes. After that I literally forget I have it on. It's just not an issue. Connectivity is not an issue, either. Setup has been easy and it stays connected to my iPhone 6+ without issue.
Things I'd like to see improve:
- there are times where I feel like I'm tense but Spire doesn't recognize it as such. I get that my perspective is a thought while Spire is measuring actual breathing patterns. I suppose this means that even when I emotionally feel tense, I'm still doing a credible job of breathing well. Cool. I do wish I had the ability to adjust the sensitivity of the algorithm, or increase the 'challenge level' so that it takes more to register as Calm, but that's a relatively minor quibble.
- I cannot stand the way the foundation pack in the Boost section handles unlocking the next boost after you've listened to the prior one. Instead of making it immediately available, it waits until 9am the next business day. So if I listen to one boost Friday afternoon, I don't get the next one unlocked until Monday morning. That's just a brain dead design.
- could be easier to get more actionable data out of the app. For example, when I just had a Calm streak or a Focus streak, I'd love to be able to add a tag noting what I was doing during that streak. That would be helpful from an analysis perspective.
And good news, these last two issues? They are directly remedied in the next version of the Spire app. They are in beta testing on it and I took a look at it, and while it's still rough around the edges it has great promise and it directly addresses these two points.
Bottom line: I think the device and the app are very useful as presently constructed. I emailed some thoughts, criticisms and suggestions to the company and was impressed to receive a detailed and thoughtful response from one of the company's founders and chief science officer. We've had a nice dialogue such that while I'm impressed with what the app can do right now, I think where it's going is simply going to get better and better.
So, do I recommend this for purchase right now? Yes, I absolutely do. I genuinely believe this is one of the few wearable technologies that doesn't just give you a bunch of data that is essentially meaningless, but can actually improve the quality of your life in important and meaningful ways.
- Reviewed in the United States on August 17, 2016Style: IndividualVerified PurchaseThis thing fell off several times a day...and then one day it was just gone. Luckily I found it after awhile and made sure to make adjustments so that this doesn't happen again. Most of the time the results are a little off - I feel stressed, it says i'm not, but its primary use is to remind me simply to Breathe when i'm playing guitar or driving - and for this it's still only so helpful- if your breathing isn't consistently stressed or diffuser or can for two consecutive minutes, it's not logged.
Update:. Android version sucks. Undeveloped, it never smart connects, I have this thing on and I'll open the app only to see it didnt record the last four days. That's ridiculous. It should always open app when data is coming in, it should save 24 hours of info in-between app acess, it should let me know when to charge it well in advance. Integration into my life has been frustrating. Lost, not charged, not paired, not in range, not accurate.... Plus when I'm tense it shows me a big ole red screen = making me more tense. Not to mention it shows me nonsense like I've been active 8 minutes, sedentary for 2 and somehow managed to take 5,000 steps and burn 2,400 calories. Really Stupid. Android version is like trying to exercise in a sleeping bag. Oh, and changing settings is a sliding scale, so say I want 5000 steps to be my goal, well I hope 5,101 or 4,982 works for you because it's impossible to set it accurately. What idiot set that up??? Don't recommend 5,000 steps and then make it utterly impossible to set it. When I double click it should adjust to a she number/recommended setting. I should be able to type it in as well. Not to mention that, inexplicably, I have to be stressed for two while minutes, uninterrupted, for this thing to be useful.... I don't want to be tense for more than a minute, why isn't 30 seconds or a minute an option??? Two minutes!!! I'm pretty sure I don't need a device to let me know that. I need something that senses it immediately.
Update-. I wear this all day and get two hours of data out of it. Pairing is a pain. Got a free replacement and still think it's a bum deal. Don't recommend
All in all, cool idea, just not ready for Android. The iPhone version was better. But still a half baked device
Update: I've worn a charged unit for four days and it recorded less than ten hours of info. This happens all the time. These things are junk!!!
Always be on and connected. Notify me of dying or dead battery in my phone and unit. Forget two minutes minimums, ten seconds of stressed breathing - I want to know. If I hold my breath unconsciously - I want to know immediately! And account for all the time wearing it - not these two minute little pockets scattered throughout the day.

3.0 out of 5 stars Enjoyable but Misleading
Style: IndividualVerified PurchaseI liked that it does make you more aware of your breathing and stress. It does track your breathing. The texture and the product are very attractive.
I don’t like that it takes such a long time to sync up with your phone. When you don’t have the app open and your phone in your pocket or bag (like when you’re at work) it has to sync. It can take 30 mins to sync.
The packaging on arrival was CRAP. You pay soo much money and it’s literally in a blister pack with no instructions or explanation or website to follow on. It’s a bit of a joke.
I would reconsider my purchase now that I’ve used it. It’s such a steep price for what it does. If you need mindfulness try mindfulness apps. They’re less expensive too.

1.0 out of 5 stars A used and broken spire arrived 25 days late
Style: IndividualVerified PurchaseI let my guard down when I chose this seller. They had no reviews yet...
Fortunately Amazon gave me a refund. Thank you Amazon!
The spire stone had no vibration, and was reading movement poorly as well so I didn't even get to try it out.
Spire is antiquated anyways with these awesome new smartwatches. I just really wanted a device that would remind me to breath deeply when I stop.

5.0 out of 5 stars Great product! Worth It!
Style: IndividualVerified PurchaseGreat product! Works really well. Seems very accurate at tracking the steps and forces me to take deep breath during the day with gentle reminders.
I had a minor issue with the clip. I contacted service and instead of sending me a clip, they sent me a whole new Spire. They were amazing to work with. Would definitively recommend the product.
- Amazon CustomerReviewed in Canada on January 8, 2017
3.0 out of 5 stars Good concept, poor execution.
Style: IndividualVerified PurchaseThis is definitely a very useful tool, and is able to track your breathing properly and let you know when you are tense. HOWEVER, for some reason, the Spire still shows that I am "breathing" when in fact, the stone is resting very still on a table, so I have no idea why it is doing this. When I tried to contact customer support, no one responded for days, and still hasn't. Strangely enough, it doesn't record the breathing patterns when it is left on a steady surface, but it just shows that there is breathing. Something is still very buggy about this, which I am fine with since it is a new product. But, it is unacceptable to ignore my requests for help/explanations.
