### 1/5 — No longer works

*2024-03-12*

Don’t buy this, it no longer works as you can’t select this widget to display on your home screen.

### 5/5 — Lowell

*2023-09-03*

All app does is record keeping. It does not calculate VO2. Don’t waste your money

### 1/5 — Sadly, it doesn’t work

*2023-06-30*

The widget is there, but the data it pulls through is gibberish and doesn’t reflect what is in Apple’s app at all. 

I tried emailing the developer for support, but the link to email them is broken.

### 4/5 — Works

*2023-04-14*

The UI is lacking, but the only functionality I wanted was a VO2 widget, which works perfectly for me!

I’ve tried 4-5 other health dashboard apps and strangely enough none of them had a VO2 widget until this one.

**Developer response:** Thanks for the review. I believe that this is the only VO2 widget on the store.
