Finally! An HRV app that just gives me the data..
Love this HRV app that doesn't try to give me a meaningless "stress score" and charge me $10 a month subscription for it.
Response from developer
Thank you! This is exactly why I built HRVSpark. Glad the raw data, ad-free, subscription-free approach resonates with you. If you ever have feedback or feature requests, I'm always listening at: info@filamentlabs.io.
