User reviews

No free version

I downloaded this app as a recommendation, once downloaded there is no free version. It shows you what you can get if you sign up for the subscription but that’s it. So disappointing.

Can’t see my sessions in app

I can’t see my sessions in app. Really frustrating

Love

This App and the exports helped me get my diagnosis after 6years of gaslighting. Thank you.

Useful for other rhythm disorders!

I don’t have POTS, but am having tachycardia spells related to another heart condition and this app allows me to document them then record an ECG on my Apple watch. So glad I found this!

Thank you πŸ₯Ί

To the developer who has POTS, thank you.
I’ve been using this app for about a month now and it has been so helpful. I know what my personal thrust holds are, and I’m aware of which heart rate is going potentially take me out… So it is so nice to be able to attempt to live in normal life and trust that the watch is going to alert me when needed. I no longer have to carry a pulse ox around with me. It’s just made it so much easier to live with a condition that’s not easy to live with.
I had to reach out to customer service once and they got back to me almost immediately and guided me through my tech issue with ease, patience and kindness.
The only small drawback is, I have noticed that the app is about 2 to 5 beats lower than what my pulse ox and BP cuff say. But that’s a non issue.
It is really affordable and will great for providing my cardiologist reports if necessary.
