Superb app

I have been using SweetBeat for many years now. 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.

The Best

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.

Spitze!!

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!

Now working with 7th gen iPod touch

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.

Really Disappointed

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!

FAQ

What does SweetBeat HRV do?

SweetBeat HRV analyzes your heart rate variability (HRV) and stress levels to offer deeper health insights. It helps you understand how your daily activities affect your health metrics and provides recommendations for training and recovery.

What hardware is required to use SweetBeat HRV?

This app requires external hardware for accurate HRV measurement. It supports tested Bluetooth Low Energy Heart Rate Monitors or the KardiaMobile 6L hand-held heart rate monitor. Wrist-worn devices, including the Apple Watch, are not supported due to insufficient accuracy for HRV.

How does the app help with stress management?

The app monitors your stress levels in real time. If your chosen stress threshold is reached, the 'Relax' screen prompts you with deep breathing exercises and calming images to help you reduce stress.

Can I export my data from SweetBeat HRV?

Yes, SweetBeat HRV provides the capability to export RR intervals and other raw data files in .csv format. You can also email your RR and session data for offline personal analysis.

What is the KardiaMobile 6L 3 Minute CheckUp feature?

This feature allows you to measure your HRV with a 3-minute countdown timer when used with the KardiaMobile 6L hand-held device. It's a convenient way to check your HRV and stress levels at any time of day without needing a chest strap.
