Scosche Rhythm+ 2.0 Heart Rate Monitor Armband for Running, Cycling, Exercise & Recovery with Bluetooth, ANT+, Optical Sensor for HRV & RRi Data, IP68 Waterproof Fitness Tracker with 24hr Battery Life

This device is much more accurate than any other heart rate monitor on the market, to even include blood pressure cuffs and pulse ox monitors at the hospital. There are many other types of monitors, they typically take your pulse rate at your wrist or fingertips but this spot is nowhere as accurate as this device on your forearm. I don't know why or how, but it just is. Also, if you do not have a normal sinus rhythm then those other devices quicky become confused and give erroneous readings. I had to go to the cardiologist for a stress test with the O2 mask and 12 lead EKG. I asked the cardiologist and tech if I could wear this device and compare it to the pulse rate displayed by the ekg and other monitors. They were ok with it and very interested in how it would do. After 20 minutes it crushed this little test. It was spot on for my resting heart rate, max heart rate and only slightly lagged the EKG by a second or two. This is phenomenal and it is hard to relay how wonderful this is, as every other device I've used (to include fitbit and chest heart rate monitors) were unable to accurately measure my heartrate as it changed under different levels of cardiac stress. They did ok for my resting heart rate but could not give accurate and/or instantaneous readings of my actual heart rate while working out. The doctor was blown away, he stated that he had never seen a device on the market as accurate as the scosche, let alone a heart rate monitor that could accurately give instantaneous readings of people with arrhythmia's. I've been an athlete my entire life. I did crew and soccer in high school and college. I've done marathons, triathlons, 100 mile rides...etc. I've tried countless heartrate monitors, polar, suunto, Fitbit...etc and none could come close to me measuring my carotid pulse for 6 sec and multiplying by 10. (Or an entire minute) This device delivers, it's simple and accurate. It doesn't slide down like chest straps do when you do long runs, I don't have to apply any gel to leads. It just works and I know it's as accurate as a 12 lead EKG. It may not tell me that I have a t-wave abnormality or preventricular contraction but it continuously and accurately gives my pulse rate. The battery lasts about 5-7 one-hour workouts. After that, the pulse rate isn't as accurate. I know what a pulse rate of 140 feels like for me, so when my watch or phone displays a pulse rate of 90, I check my pulse and realize the device is not relaying correct data and I need to charge it. Once it's charged, it's good to go again. It syncs to most devices quickly as it uses standard ANT+ and Bluetooth. Bottom line-this works so well it surprised my cardiologist and I trust it with my life. I actually wouldn't workout without it anymore.

I've always hated chest strap HRMs, so I've been looking for something I can wear on my wrist or arm. I've been a Fitbit fan since its first days, so I thought I'd pick up a Charge HR in addition to the Charge I already wear daily. Unfortunately no matter how I adjusted it, I couldn't get a reliable HR signal. I'd bought the small (fits my wrist just fine), but doesn't have enough length for me to wear it much higher on my arm. I also discovered it doesn't work all that well with my Samsung Galaxy S5. So I returned the Charge HR, continued my research and happened upon the Scosche Rhythm Plus. This thing is fantastic! It works great with Sports Tracker Pro (my fitness app of choice) through Bluetooth. The app (and my phone) have Ant+ too, but I haven't been able to get the Scosche to keep a connection after I leave the settings page on the STP app. It's either user error or something with the app, I'm sure, so I'll figure it out eventually. In the meantime, it maintains a solid connection with Bluetooth and seems very accurate. I can still use my bluetooth headset as long as I connect it prior to launching STP and connecting the Rhythm Plus. I've been using it for good form fast walking but intend to use it while biking and working out on the Total Gym too. It's important for me to wear a HRM not only for motivation, but to keep me from overdoing and injuring myself, as I have lung disease. This is a GREAT, comfortable HR monitor! Update Nov. 8, 2015: A couple weeks ago I noticed a hairline crack on the sensor side of the Rhythm+. I'd never dropped the unit or otherwise abused it, so I assume it was a stress crack. I emailed Scosche support, and I got an almost immediate response with an RMA request form attached. I shipped my Rhythm+ the next day, and about a week later, the replacement was in my mailbox. The replacement's working great, and I'm hoping it lasts longer than the original.

I bought a Scosche HRM over 6 years ago. It still works, but after heavy use (6X a week), it no longer holds enough charge for my multi-hour bicycle trainer rides. I've been otherwise completely satisfied with it. So, when I decided to buy a replacement, I chose the Scosche Rhythm R+2.0. I've worn it (on my bicep) for several rides, including four, 3+ hour rides this past week as part of a 500km cycling challenge. Its performance has been perfect. Its accuracy is identical to my older Scosche and another brand's chest strap HRM. The newer style armband feels more comfortable and seems to provide better sensor contact than the older Scosche armband. Once it's on your arm, the band also provides a more secure fit and, because it doesn't use Velcro closures, it's less likely to accidentally pop open from incidental contact. The 2.0 charges faster than the previous Scosche, even when my previous one was new. And finally, I was very impressed with the price. I'm pretty sure it was less expensive than the one I bought years ago. That doesn't happen much anymore. The only complaint I have with the 2.0 over the previous Scosche is that it takes a little firmer, and seemingly longer, push on the front of the HRM to turn it on and off. But that's so minor, that it's barely worth mentioning. If you are like me, and don't like wearing a chest strap HRM, then I recommend you give the Scosche 2.0 a try. It's an accurate, comfortable, secure, and affordable way to measure your HR during your workouts.

UPDATE: 5 weeks in I am now reducing this review to one star. I feel very lucky when this wristband actually syncs. It's becoming a rare event these days. This was a purchase I know deeply regret and the return period is over. Please pay attention to the negative reviews. This product really is garbage. UPDATE: A week after writing the review below, I am removing two stars. The Scosche continuously connects and disconnects during my Peloton ride. This is kind of alarming given the fact that the rider wearing the device is right on top of the Bluetooth connection. I have thrown away the packaging so I don't know if I can return this, but I don't think I can confidently recommend this anymore. Many Peloton users are recommending POLAR brand instead. ============== I advise anyone looking to get a Peloton to save some money and not buy the ESSENTIALS package with the mat and heartrate monitor. You can do better for less. I have already reviewed a great mat that you can look at if you click on my username. The Scosche Rhythm+ has been wildly recommended by Peloton users for its compatibility with the bikes. However, Amazon reviews are all over the place as far as the accuracy and long-term reliability of this device. You can imagine that I wasn't exactly comfortable with this purchasing choice. So far, the Scosche Rhythm has been working rather well for me. I do like the fact it's an armband and not some uncomfortable device that goes across the chest (as is with the Peloton heart monitor) I can't tell you if this thing is accurate or not as it has become my sole tool for determining my heart rate during spin class. I will say that it does connect without any hesitance every time I turn on my Peloton bike screen. This is a big sigh of relief for me because I don't need to be fiddling around with a connection every time I want to exercise. The heart rate shows up in a big indicator block on the Peloton screen. Connection is always solid. No dropouts. My only complaint would be the lack of any charging indicator on the device. You also need to learn how to do a long or short press to turn the Scosche device on or off. The first time I used it I forgot to turn it off and the battery was dead upon second use. I would have hoped the Rhtyhm+ would turn itself off automatically when not in use, but that does not seem to be the case. Charging the device is very simple. It snaps into a plastic charger. It only needs 2 hours of charging time. There are also extra arm bands included. In all, I am happy with this purchase but I am concerned by the negative reviews. If this thing konks out on me you can bet I will be back to update this review. In the meantime, based on my initial impressions, I would recommend this for Peloton users!

I bought this HRM as an alternative to chest straps, which are still considered the gold standard, but can be a little awkward at times(I wear an HRM at the gym as well as cardio, so the chest pod can get compressed during certain exercises) and can chafe even if you keep in clean, use gel, etc. Overall this a pretty strong device: It syncs well with my Garmin FR230. It is comfortable (I wear it fairly tight and still do not notice it during workouts), fairly flexible in wear (based on your size and which strap you choose you can wear it on a forearm, bicep, wrist, and probably even an ankle if that suits you), and pretty accurate. I have used it interchangeably with a Garmin chest HRM and an chest worn Accuro HRM304 and get about the same numbers on each device. Why don't I give it 5 stars?: It is not perfect. The light-based HRMs are getting better but still seem a bit slower and less accurate than chest-based ones. If you're mostly into steady state cardio, this could be the perfect device for you. If you do a lot of interval training, you may find it lagging in accuracy. I have used it for sprint intervals on a treadmill and it struggled to keep up with the changing pace. Another con: once in a while, it will be wildly inaccurate. I am not sure what triggers the flaw, but it will basically "bury the needle" on your HR regardless of your activity level. Example: I took it on a trip where I had access to a nice trail and didn't want to pack the chest strap and electrode gel. I did several early morning 4 mile runs with it and it was rock solid. One afternoon my wife suggested we walk the trail. I turned on the Rhythm+ so I could track my calorie burn and it started just fine, but a mile in, I looked down and it said my HR was 195. I was clearly not sprinting so that was about 2x of what it should have been. I stopped for a few minutes and it dropped as low as 190 but clearly was stuck. I tried to power cycle it, but still was not wanting to read (and yes I manually checked my HR just to make sure I was not having some issue). I gave up and finished the walk. The next morning's run it was working just fine. I have only experienced that about 5 times in a year, but still it is often enough that I tend to not trust the device for running anymore and tend to use it only at the gym. Bottom line- this is a good device, but if you want the best accuracy, stick to the chest strap. My suggestion for the best chest strap is the Accuro HRM304. It is a small company and I took a gamble on buying it, but it is the only device I know of that syncs with Ant+, Bluetooth, and Analog all in one, so I can use it with my Garmin watch while simultaneously sending a signal to the gym equipment or my AirDyne Pro at home.

I've now owned this product for 2 months. I wanted to give it some time before posting a review. New and shiny normally = 5-stars. So I wanted to test it out first. The monitor works great! It was easy to pair with both an iPhone 5s and an Android LG G2 and G4. The connection never broke with my device and works very well with RunKeeper. I have not tested it with other fitness apps, but RunKeeper will call out the heart rate if you set it up that way. Surprisingly, Scosche does not have their own app. I wanted to use it just to randomly see what my heart rate was and had to download a standalone app for that. The instruction booklet is short and to the point. The one I received was a little outdated. For example, once I was running and saw that the light was blinking red. I associated this with a dead battery or that something was wrong. So, mid run, I tried cycling it on and off. Still blinking. So I just let it go and figured it would die. RunKeeper continued to call of heart rate info. I thought it was because it was "guessing" based on the previous miles of information. However, when I reviewed the data, there was a graph. After some research, I found an additional instruction booklet online that stated blinking red means you are in your maximum heart rate range. Blinking purple means you're in a normal range. There are four bands. Two green and two black. The bands are for your wrist (or an extremely skinny person) and your forearm. I've tried both with similar results. However, I've read that a lot of sweat can interfere so I keep it up on my forearm as sweat normally collects around your wrists. The bands are comfortable. I gave the green to my wife and I use the black. The proprietary charger is a small contention I can live with. Micro usb would be nice, but I can understand keeping openings closed so the device doesn't get moisture inside. Just don't misplace the charger. At this price, it's WAY better than built-in heart rate monitors on watches.

I purchased this with the hope of getting more reliable heart data with my Apple Watch Series 3 (http://amzn.to/2Dj1BJ7) during cycling workouts. When cycling, I found that the readings would sometimes take 2-3 minutes to register, which was annoying (for example, rapid changes in heart rate associated with a climb, or ambient light flickering like when I ride through partial shade or trees, seems to confuse the sensor). I like using the default Watch workout app, and wanted my heart rate data to be stored in the same place (Health app) it would go if I used the native heart rate sensor. I did not want to have to switch over to a proprietary app associated with the armband. This band worked perfectly. First, I was able to pair directly to the Apple Watch. I had some trouble at first but rebooting the watch got it working (and it hasn't had any issue since). Once connected, the heart rate data was constantly updating, and the light on the watch was not even on, so I know it was coming from the armband. Second, the readings were very consistent for the most part, and the volume of readings was much greater than the Apple Watch. After a workout, the heart rate chart was much smoother (with many more data points) than the built in sensor. Faulty readings are rare but when they do happen (for example it detects 60 bpm when it is really 120bpm), it can take 30 seconds or so for the rate to "recover", it will slowly climb. But it's not a huge deal, as it happens relatively infrequently. Bottom line, if you have an Apple watch and like to use it for exercise but wish the heart rate sensor checked more often and consistently for your heart rate, this is perfect.

I wanted an armband monitor mainly because I consistently forget to put my chest monitor on before my cycling base layer and bib straps. I then have to strip half way down just to put on my chest strap. Silly, I know, but happened often enough that I tried the switch. Pros: - Easy to put on regardless of how clothed you are - More comfortable than a chest HRM, especially when wearing a pack - Tracking (when it stays connected) is on par with my chest HRM Cons: - Often drops connection with my Garmin Edge 530. It regularly stops displaying the HR info on my screen and will pick up a few seconds, to minutes, later. It dropped 13 times on a 64-mile ride recently and records exactly 72bpm to the .fit file when it drops. The downward spikes on my graph are apparent because I'm often keeping my HR in the 140-180 range. - Similar to dropped connections, I've had to remove it and re-add it to my Garmin several times for it to be recognized before I start a ride. I've never had to do this mid-ride so I'm not sure if they're related. - You have to manually turn it on and off—and remember to do so every time. I just snap my chest HRM on, it connects to my device(s), I do my thing, snap it off, and throw it in my bag for next time. I repeatedly forgot to turn the Scosche on before a workout and then off again when I was done. This lead to missed initial tracking and a dead battery for my next workout. I eventually got into a routine, and it was just another thing to check off my list, but the chest HR is foolproof in comparison. - Battery life is poor. I knew this would be different from my chest monitor but didn't think it'd be a big deal. And really, it's not a huge deal, but you have to remember to throw it on the charger frequently. While I can get a few short weekday rides out of it before thinking of charging it again, my weekend rides often last hours and I regularly get a low battery alert on my Garmin. This happened recently on a 7-hour ride and it started warning me around hour 6. This is after a full charge. My chest HRM battery lasts for months and all I need to carry is a small CR2032 as a backup—not a big bulky case. - Strap is fiddly. Once the strap is connected, it's solid, but will pop off at the slightest angle or twist. I believe this to be the intended design but I've often popped both sides off while trying to put it on or take it off—separating the monitor from the band. In comparison to the snaps on my chest HRM, the clasps feel cheap and don't provide a satisfying snap into the monitor. I often double-check that it's secure. I really wanted to like this but it's not for me. My cons might seem trivial but they're not something I'm willing to deal with. My chest HRM is dead simple, never need to worry about it connecting to my devices, or worry about charging it—it just works. Maybe it's a Garmin ecosystem thing. However, it was also spotty with my Concept2 rower and iPad (TrainerRoad) so maybe not. Regardless the issue(s), I'm sticking with chest HRM.

Muy practico y facil de colocar en el brazo. Lo apago despues del ejercicio, cuando lo enciendo de nuevo, de inmediato conecta el GPS, cosa que no pasaba con mi reloj Huawey que constantemente se desconfiguraba el GPS

Love this! It's accurate and comfortable. My only gripe is that it slip down from time to time, might just be that I haven't got the strap just right as yet. Right on particular with my H7.

The best heart rate sensor in terms of accuracy. I wish this model had cadence as well for riders but that was added later in rhythm24. Overall, this is still my go to monitor for pairing with my Apple Watch

In canada we don't have a access to order scosche HRM products so I opted to purchase this one from Amazon. Took only 3 days for delivery. The seller I'd great and responsive with any question. The heart rate monitor works great, battery lasts a while and it's easy to use.

Although my Fenix 5 plus is quite accurate, it can take its time tracking changes. This gadget is fantastic!
