Redesigned dashboard surfaces your latest VO₂ max, rolling averages, and personal best with widgets that follow your selected range.
VO₂ Max shows how much oxygen your body can absorb at peak effort. The redesigned dashboard puts the latest measurement, rolling averages, and your personal best in one view so you immediately see how training affects cardio fitness.
ESTIMATES FOR RUN & BIKE
- New tab turns VO₂ max + weight + power into W/kg and FTP estimates for running and cycling.
- Compare modeled race times and power against your actual HealthKit FTP/power.
NEW DASHBOARD
- Trend cards highlight the 7-day average, any selected range, and your best value with percentage deltas.
- The interactive chart responds to 1W, 2W, 1M, 3M, 1Y, or All filters and animates every new HealthKit reading.
- Entry tiles list the test type, source, and timestamp so you can compare prediction and max-exercise tests.
INSIGHTS & GUIDANCE
- The info sheet matches your value with the correct age and sex bracket to explain whether it is poor, good, or superior.
- Manual refresh, HealthKit warnings, and empty states keep permissions and sync issues obvious.
- Trial countdown and subscription access stay a tap away.
APPLE WATCH + WIDGETS
- All complication families are supported, so your latest VO₂ max is available on every watch face.
- iPhone Home Screen and Lock Screen widgets follow the dashboard range you selected.
- The Widget Showcase walks you through pinning widgets or complications and previewing layouts.
HOW VO₂ MAX IS CAPTURED
1. Start an outdoor walk or run with continuous heart-rate tracking for at least 20 minutes.
2. Keep the Workout app running with GPS enabled so Apple Watch can estimate the value.
3. Grant VO₂ Max access in the Health app so the dashboard, widgets, and complications can display the data.
Requires Apple Watch Series 3 or later. VO₂ Max makes it easy to see if your cardio fitness plan is working today, over the last weeks, and all time.

Love the new update with the Cooper test, but for the developer: the moment one enters a number into the Cooper test field, the app becomes unusable because you can’t leave the page anymore. Whoops.
Developer Response
Thanks for the feedback, you’re absolutely right. We fixed the issue where the keyboard could trap you on the Cooper test screen, and the fix will be in the next update.
New Version, you now buy it AGAIN.

Hello: I purchased this app and all other apps from this developer for the purpose of using them on my watch. Back then they all had a one time price. Now this app just got updated and guess what it became a subscription based app. Or you could “buy” it AGAIN. The app will say that a previous purchase from the old system will be honored, but nope. It doesn’t do anything when you authenticate to restore your previous purchased version. If you are a new user to this app, be ready to pay a subscription or a $7 fee for a “lifetime” membership. If you are an existing customer, thennnnnn be ready to do the same. Until the developer updates the app in the future and erases your past purchase and you have to buy it AGAIN.Don’t get me wrong. Is a good app and does what is supposed to do on your watch. The price is not too bad either, but is just the principle of being made to pay again even though you already did in the past, regardless of the price.
Another purchase fee??? Update

Update: the developer contacted me, apologized for the situation, and honored my original purchase. I was really surprised to hear back from him so quickly and I appreciate his response. The app is fully functional and I’m able to access everything as before. So 5 stars for the app and customer support.Bought the app before it became a subscription service. Now developer wants more money for a “lifetime” subscription. Option to prove you paid before doesn’t work. Is it worth another $7?
Developer Response
Sorry, I made a mistake when migrating existing customers. Could you please send me an email at info@bernhardhering.de? Best, Bernhard

I love this app. I consider vO2 max perhaps the best indicator of overall aerobic fitness, and this app allows me to see how, overall, I am doing over time. It’s basic, sure, but it’s totally reliable, I don’t have to start and stop, and it also shows where I stand in my age range. The only change I’d like is to show data for more/longer than only a year.
Fixed an Apple Watch crash during launch and widget loading.
Improved Siri shortcut recognition for VO2 Max.
