## VO2 Max Calculator Reviews in United States

### ****- "1 year"
I only review products I’ve used consistently for at least 1 year. 

I was frustrated when I first downloaded it because the age font is small enough that I couldn’t get it to adjust. I worked that out after a few tries. 

My first few readings were high, these were taken without exercising, but when I took it during or immediately after a workout I found that it gave me a relatively close, although a bit low, reading. 

It has to be tight on my wrist to work properly. I now take 4-5 readings throughout the day with at least two during my workouts, then I average the results. 

For a free app I thinks it’s a great tool when used properly. Don’t expect to get a highly accurate reading from it, the technology just isn’t there yet, however using this beats paying thousands of dollars a year and cumbersome equipment to get a daily vo2 max reading.
-- Mike S1,000, 2023-11-21

### *---- "Yeah no…"
My VO2 max was calculated to be 81!!!! NO WAY!!!! DELETE
-- Don’t download 1, 2023-02-02

### *---- "Loved how this worked"
Completely inaccurate. My VO2 should be terrible but my result was 80. Free app or not there is no excuse for not following the equations available.
-- JoeyBones621, 2023-01-25

### ****- "Will have to do more testing"
For everyone that is complaining that it’s a waste of money, it’s a free app. I appreciate the fact that the developer created an app that doesn’t require in app purchases.

I’ll have to see if this is really that accurate. I’m sure it’s not as accurate as sports physiology testing equipment. That’s OK, provided that it is consistent. If it shows improvement overtime, it’s probably a useful tool to determine whether or not your cardiovascular fitness is improving. I’m not so worried about the absolute number, but I do hope that it is consistent and can be used to track progress overtime.
-- BWU2112, 2022-12-29

### *---- "Don’t waste your time"
The app just doesn’t work. I get no results when using.
-- Jude in DC, 2022-11-25

### *---- "Waste"
Doesn’t work
-- MoneyMike31, 2022-10-21

### *---- "This app does nothing, purchased, set my age, and then it doesn't capture my hr."
Waste of a purchase.
-- jb1hammer, 2022-08-26

### ***** "Thank you, Theo"
Suffering from COPD, the app helps me with keeping the eye on my cardiac health.   Nothing is perfect, but it has helped me move in the right direction.  Thank you.
-- duane_kevin, 2022-04-16

### *---- "Nope!"
I just had an actual VO2 test done at a performance medicine institute and this app overestimated my my performance by 18! That’s an awful lot.
-- WanderLit, 2021-10-08
