By analyzing HRV and Stress along with additional data, SweetBeat HRV provides a deeper dive into health and provides insight into what activities you engage in that effect the health metrics you care about. IMPORTANT: SweetBeat requires external hardware: A tested Bluetooth Low Energy Heart Rate Monitor or KardiaMobile 6L hand held heart rate monitor. While other manufacturers wrist worn devices work well for heart rate, their wrist worn heart rate monitors are not accurate enough for HRV and so are not supported. The iWatch is not supported. •Please visit https://www.sweetwaterhrv.com/healthsensors.shtml for a list of compatible Heart Rate Monitors devices. SweetBeat HRV will also import your Apple Health app data (SDNN, Resting Heart Rate, Average Heart Rate) that is collected by the iWatch or other devices authorized to store metric in the Health app. This data is for viewing purposes only and is not used in any HRV calculation. SweetBeat has two main components: •Monitor Stress •HRV for Training/Recovery •KardiaMobile 6L 3 Minute CheckUp Monitor Stress: With SweetBeatHRV, you can see your stress levels in real time, giving you the ability to take action to reduce stress. If your chosen stress threshold is reached, SweetBeat’s Relax screen prompts you with a deep breathing screen that includes calming images. •Stats: The stats screen more widely referred to as the “geek” screen, shows all the metrics being measured. If using the HealthPatch, the user can view the additional provided metrics. •Graph: The graph screen shows a real-time building graph of your heart rate from RR Intervals. Turning the phone 90 degrees counter-clockwise will bring up the graph in landscape. •Export RR Intervals: SweetBeat provides RR interval export capability along with other raw data files in .csv format. HRV For Training: In competitive sports, improved performance is often affected by alternating periods of intensive training with periods of relative rest. SweetBeatHRV measures HRV, an objective measure of your body’s response to each workout and provides training recommendations based on the morning reading. KardiaMobile 6L 3 Minute CheckUp: With SweetBeatHRV and the KardiaMobile 6L hand held device, you can measure your HRV with a 3 minute countdown timer. This type of session can be used conveniently any time of the day when you want to check your HRV and stress levels. The KardiaMobile 6L hand held device is convenient and eliminates the need of a heart rate monitor chest strap. Please note that the KardiaMobile 6L device is the only KardiaMobile device that is presently supported by SweetBeat HRV.

I tried other HRV apps along the way but I find SweetBeat superior in almost every way. Nothing gimmicky just good solid - and extensive - data. I love that the focus is data - everything I could wish for including HF, LF, and even VLF (which adds another dimension). Also extras like respiration rate & heart accelerating and decelerating capacity. Beautiful graphics and fantastic support from SweetBeat if needed. Thank you for a really great app that has helped me enormously and made my life better. ### 5/5 — The Best *2025-01-03, version 2.6* I love this app, use it almost every day. It has so much data but thoughtfully broken out onto various screens so the amount of information is never overwhelming but still easily accessible. This app is a real service to the community. ### 5/5 — Spitze!! *2024-07-30* Zwei Dinge verstehe ich hier nicht! 1. Warum gibt es so gut wie keine Rezensionen? Ist diese App wirklich so unbekannt? 2. Die einzige Rezension, die ich hier gefunden habe, ist völlig unverständlicherweise auch noch schlecht. Ich setze mich nun schon sehr lange mit dem Thema HRV Messung auseinander und habe doch wirklich, wenn wahrscheinlich auch nicht alle, aber so doch die meisten Apps im App Store zu diesem Thema ausprobiert. Und diese App spielt ganz vorne mit! Man muss lange suchen um eine App mit diesem Funktionsumfang und somit auch Auswertungsmöglichkeiten zu finden! Diese App hält locker mit der hoch gelobten Elite App mit. Und mit dem so genannten Goldstandard Kubios allemal! ### 5/5 — Now working with 7th gen iPod touch *2023-05-05, version 2.2* SweetBeatHRV has been a game changer in allowing me to manage/rebuild my functional level with my MCS. The amazing support team worked with the app until it worked on my 7th gen ipod. Such a treat. Love the updates, especially adding the real time . Many thanks for your hard work. ### 1/5 — Really Disappointed *2023-04-19, version 2.2* I have been using SweetBeat for almost a year and would have highly recommended. I have kept the older version on my phone as i wasn’t keen on the new changes. This morning when i went to take my readings the newer version had automatically uploaded and due to the oversizing issues not bring ironed out for iphone SE the app is no longer useable. Hugely disappointed. I have a mini ipad which the app is also useless. Avoid if you have these devices! ### 5/5 — There’s a reason why this isn’t free *2023-01-28, version 2.2* I have used most if not all of the available hrv apps and this is without doubt, in my opinion, head and shoulders above them all. Not only does it offer a user friendly interaction, it also provides more technical content for those that are interested. The people at SweetBeat are experts in this field and it’s apparent that they have invested a lot of time in researching this subject, as well a developing an algorithm that effectively presents very accurate usable data. I especially commend their artefact removal (ectopic beats) as this was always an issue for me in other apps. Absolutely well done team! Please continue your superb work! Ps I was offered a free copy of this app, but declined in favour of paying; it’s that good. ### 1/5 — Upgrade is trash *2021-07-05, version 1.6.0* Since I did the software upgrade that was recommended recently the app no longer functions. I cannot see any of my of hrv's and when I take a new reading it shows everything but the hrv. ### 1/5 — Won’t pair, no response from company. Buyer beware. *2020-12-10, version 1.5.0* Despite claims that this works with the Withings HR, it won’t pair with the watch. To make matters (much) worse, emails to Sweetbeat asking for assistance or a refund have thus far gone unanswered. I’ll keep trying to get my money back. Buyer beware! ### 1/5 — Scammed *2019-11-19, version 1.5.0* Almost nothing worked , app insisted I buy redundant hardware, the few charts that actually worked with my Apple watch were unreadable and a joke. Would have enjoyed lighting $10 on fire more.... ### 4/5 — Great live monitoring for HRV and stress *2019-10-15, version 1.5.0* I’ve been using a few HRV apps with polar chest strap for over a month now. I love SweetBeat for seeing live monitoring of several things at once including HR, HRV, stress. However, the recommendations it gives me after analyzing my data are totally different then how I feel or how my 4 other HRV apps analyze the data—all running at the exact same time. It also is the only one that says my parasympathetic system is active when my other apps say it’s severely not active at all (I have dysautonomia and am finding what works for my systems to have more PNS activity when needed than SNS activity, and I track and graph PEM for pacing with myalgic encephalomyelitis.) I would imagine those tracking fitness or managing stress, can also use accurate info about their ANS. I definitely wish I could turn off the “you should do x, y, or z today.” The “gas tank needle” graphic indicating ANS balance has been way off compared to my other apps running at same time. I love that it has a non-annoying HR alarm (a little whistle) but I wish it would continue to sound until the HR was back lower—Would love having option to fully customize HR zones and HR alarm (like keep alerting until HR is back under threshold.) Custom HR color zones would be extra great. I really need it to be iPad screen size. Thank you for taking my suggestions and for making this app. ## Frequently asked questions about SweetBeat HRV ### What does SweetBeat HRV do?
