### 1/5 — Garbage

*2026-07-23*

This is a notebook application, you do not measure anything, including on Apple Watch, you enter the data itself and this data is stored as in a notebook. How did it get a 4.6 rating? Delete.

### 1/5 — Meter app

*2026-03-19*

This is a scam does measure oxygen and won’t let you cancel during free trial

### 1/5 — Can’t delete

*2025-08-26*

I downloaded this because I thought it would work with my watch, but it’s actually for a device, I can’t delete it, I’ve deleted it five or six times from my phone and it still keeps coming back.

### 5/5 — Wow!

*2025-07-08*

Wow

### 1/5 — Waste of time

*2025-06-28*

Does not measure O2 saturation.

### 1/5 — No brinda instrucciones de uso ni compatibilidad con la versión correcta de Apple Watch

*2025-06-09, version 1.2.4*

No es compatible con mi Apple Watch y no lo avisa en la aplicación. No te ofrece un manual de uso ni tutorial para iniciar. No le entiendo a la app.

### 1/5 — Misleading

*2025-04-20*

Subscription service

### 1/5 — Inaccurate

*2024-11-11*

The app isn’t accurate at all. The subscription is a scam because you can’t try the app before paying.

I verified the results of the pulse with a known good device. The app was off by 20 BPM.

The description leads you to believe that it reads the O2. It doesn’t.

### 1/5 — Refund money please

*2024-09-23*

This doesn’t take your blood oxygen I would like my money back. I’m very disappointed.

### 1/5 — Does not work

*2024-09-04*
