### 1/5 — Doesn’t work

*2024-05-30*

No matter how bright my environment is, it’s not able to detect my face

**Developer response:** Hi! We’re sorry that VitalLens isn’t working well in your case. Both face detection and vitals estimation can be affected by factors like movement and lighting. If you’d like, email us at vitallens@rouast.com and we can work out a solution for your case.

### 5/5 — It actually works!!

*2025-11-11*

Really neat idea that they turned into an actual product

### 5/5 — Surprisingly Accurate

*2025-01-04*

This is super consistent with the readings I get on my Apple Watch. In 5 trials, it was always the same or within one bpm of what Apple says. 

I have a very low heart rate, so I am even more surprised since my ratings are outliers.

I have no idea what I will do with this app, but it’s fascinating.

### 5/5 — Awesome idea and model :3

*2024-12-21, version 1.0.6*

Works great! From previous correspondence with the developer, strikes me as both a brilliant and genuine person

### 5/5 — Great app

*2024-10-06, version 1.0.6*

I tried it and works!! Very cool

### 5/5 — Amazing app

*2024-03-02, version 1.0.3*

Great set up and inter face. I love that it keeps a record and is so easy to use
