Long battery; but wrist HR tracking is inconsistent.

Running these analyses costs money. Buy through my links to help keep lights on! I may get a small commission.
Ditto re the battery life. I have next to no set routines so for a space cadet it is bloody brilliant… I lost my charger for over a week and a half and it’s still cruising along - vs my Apple ultra, which drives me mental with how often it needs a lifeline.
If I had your goals, I'd almost certainly go in for the Whoop. It does a great job with sleep, HRV, and activity tracking if nothing else. I haven't heard about anything that compares with performance in those ways together with convenience. The 5.0 battery life is also a huge quality of life upgrade. It feels like I barely have to charge it, so it's just always there in the background and not bothering me. No more tamagotchi energy like the old ones.
My own personal data showed different for HR accuracy. Apple Watch Ultra 3, Pixel Watch 4, and even Garmin Forerunner 965 did very well compared to Polar H9 chest strap. The Amazfit Helio Strap was even closer. But, Whoop 4.0 and 5.0 devices are just "all over the place" for HR. I don't have an Oura to compare [https://imgur.com/a/C0eXjXl](https://imgur.com/a/C0eXjXl) These are all walking on a treadmill at 3.0 MPH to try to get an "easy" workout for the devices (so no running, no cycling, etc)
I have a charge 6 and bought an Air in black a few days ago. The metrics are the same minus any of the extra Google features and on demand functions the screen gives you. For me the charge 6 is more comfortable to wear. It may be a touch heavier but I don't even notice it. Even when sleeping. The way the Air sits on my wrists makes it less comfortable since the band forces it to not completely lay flat without using too much pressure vs the charge 6 is more spread evenly. Maybe that'll change as new bands come out. I prefer to wear the charge 6 when I sleep as well. I wish the Air was my preference since I'd like to wear a normal watch without looking weird along side the charge 6. I mainly use it for sleep and steps. With the step counting that really doesn't fit a bicep band. I even find the heavier Whoop 5.0 more comfortable with it's basic nylon band.
Ich benutze Whoop MG also 5.0 jetzt fast ein Jahr. Und ich werde verlängern. Whoop hat mir soviel gebracht. 30 kg abgenommen durch gezielte Lebens/Trainingsführung durch Whoop. Mein Blutdruck ist nach über 30 Jahren wieder stabil, so dass mein Hausarzt und ich dabei sind mein Medikament Metoprolol 100mg auszuschleichen. Nehme jetzt nur noch 23,7 mg. Ich habe inzwischen ein Laufband und einen Radtrainer zu Hause und genieße es sie zu nutzen. 2 bis 3 mal in der Woche gehe ich ins Fitnessstudio. Mein Leben hat sich total zum positiven gewendet Dank der Werte und Unterstützung von Whoop. Dank der KI von Whoop und der doch sehr individuellen Betreuung. Ich möchte noch erwähnen das ich zusätzlich zu den 24/7 Whoop tragen auch noch RingConn Gen 2 nutze und Garmin mit verschiedenen Sensoren. Also ein Rundumpaket. Ich kann Whoop nur empfehlen.
Ja Whoop ist sein Geld wert, wenn man viel mit der Ki spricht, sich an die Empfehlungen hält und die Daten wirklich verinnerlicht. Ich habe das Life Abo mit dem MG Band und super Erfolge erzielt. Seit Mai letzten Jahres habe ich 35 kg abgenommen weil ich animiert wurde wieder Sport zu machen, mein Vo2Max ist von 29 auf 54 gestiegen, mein Whoop Age von Beginn 65,7 Jahren auf 50,6 gefallen,tatsächlich werde ich in ein paar Wochen 60. Ich lebe Whoop und bin glücklich es gefunden zu haben. Noch etwas. Ich habe seit über 30 Jahren Metoprolol gegen erhöhten Blutdruck nehmen müssen, 100 mg am Tag. Jetzt nehme ich noch 11,9 mg täglich und ausschleichend. Ich bin sowas von gesund geworden, man glaubt es kaum.
Hey ya’ll! Just wanted to post this as a thought post for those trying to decide whether or not to pull the trigger. The past year and a half of so I’ve been trying to figure out what device I like best when it comes to habit/wellness tracking. I’ve used the apple watch, whoop 4.0 and 5.0, the garmin forerunner 165 and the oura gen 4. While I had liked the apple watch for the longest time, I came to hate being constantly connected and having my wrist buzz all the time. The whoop was amazing for someone living a truly athletic life but as a general tracker, it was too in depth and almost felt like having an overbearing coach lingering on your wrist 24/7. The garmin was almost a repeat of the apple watch except I turned off all the smart notifications but still missed wearing a nice watch on a day to day basis. Myself and the Oura have had an on again off again relationship, this is the 4th time I’ve had it(returned the first three times). Ever since I returned the 3rd I realized how much I missed having such a discreet but good looking tracker that I also love the UI of. While it may not be the best “fitness tracker,” if you interpret your data correctly, it can help you take the habits you build and lock them in to be just that little bit healthier every time you make the connections. I’m hoping that even just this bit of rambling and getting thoughts out will help someone make the decision and make it that little bit easier.
The whoop was probably my least favorite between the nitty gritty data of the app, the constant notifs that it would send but also how bulky it feels compared to oura.
