### 4/5 — How do I download/share heartbeat?

*2025-05-23*

Hello! 
I’d love to give this 5 stars because it was easy to do and has meant so much to us but I’m lost on how to share the recordings. Maybe I overlooked it but I am not seeing a share or download button. Can you help? We just recorded my daughter’s great grandmas heartbeat before she passed away and now I’d like to send it to the family. 
Thanks for your help

### 1/5 — Scam

*2025-04-24*

DOES NOT WORK

### 2/5 — Frequent crashing

*2025-03-02*

I loved it at first, but now it forces me to click through the introduction and crashes each time I try to open the app and listen to my recordings. Wish there was a way to export the heartbeats too

### 4/5 — Needs a way to export!

*2024-10-26*

Great use of the hardware, though needs a way to export your recordings to other apps.

### 1/5 — Crashes on play

*2024-10-02*

We recorded my dying aunt’s heartbeat. The app crashes every time we try to play any recording and there’s no way to download the recording. Heartbreaking would be a better app name

### 5/5 — CATS!

*2023-07-18*

Worked great with my two cats. It smart to take heart beats before vet. When at vet can get inaccurate and subsequently dismissed tachycardia.

### 2/5 — Nope

*2023-06-27*

Does not allow you to export the audio files so that I can send it someone

### 1/5 — Cannot save recordings to iPhone

*2023-06-06*

The app only saves the recordings of your heartbeats into the app itself, not on your iPhone. The app doesn’t allow you to even export the audio clips to wav or mp3 files so that you can save them onto your iPhone or iCloud. I contacted the developer about this and they have not responded. I’m very disappointed about this. 1/5 stars. I will update my review if they update the app and allow users to export the recordings.

### 1/5 — Unfortunately can’t pick up the sound

*2023-04-15, version 1.0*

Can’t pick up the sound but if they can invent something like this in the future that is accurate I can send to my doctor this would be great!

### 5/5 — I only wish it recorded longer segments

*2023-01-18*

I get heart palpitations due to PVCs and always wondered what they sound like. I tried recording just with my Voice Memos app and it didn’t pick it up at all. This Echoes app is amazing!  I can hear my heartbeat so clear. I found that the microphone sensitivity works best on 1 or 2. I have a stethoscope for comparison and this app captures the heartbeat well. I do have to have the volume up all the way when playing the sound back. I only wish it recorded in longer segments.
