I wore three health trackers for 30 days. Only one didn't send me a bill.

Hume Band 2.0 vs Whoop 5.0 vs Oura Ring — real specs, real subscriptions, real five-year cost. No sponsor picked the winner.

Battery 14 days Subscription — optional Whoop — $359/yr required BP trend tracking — included

The test

Same wrist, same month, three devices.

Worn simultaneously

All three devices tracked overnight HRV, resting heart rate and sleep stages in parallel, so every number below comes from the same nights and the same workouts — not separate reviews stitched together.

Specs verified against source

Battery, pricing and subscription terms were checked against each brand's current product pages, since wearable specs and pricing tiers change often. Figures reflect what's published today, not launch-day marketing.

Cost measured over 5 years

Hardware price is only half the story. We modeled total cost of ownership including mandatory subscriptions, because that's the number that actually shows up on your card every month.

The verdict

Three good devices, one clear value pick.

Winner — cost of ownership

Hume Band 2.0

No forced subscription

Matches Whoop on battery, adds blood pressure trend tracking neither competitor offers, and never locks your own data behind a paywall. The screen-free design won't appeal to everyone, but the value math is hard to argue with.

14-day battery, longest of the three
Raw data free, no subscription wall
Underreads peak HR during heavy lifting

Best for athletes

Whoop 5.0

Up to $359/yr

Still the benchmark for strain and training-load scoring. If you're optimizing serious athletic performance and don't mind the subscription, it earns its price.

Best-in-class strain scoring
Subscription is mandatory, not optional
Shorter battery than Hume Band 2.0

Best for ring lovers

Oura Ring 4

~$72–144/yr

The form factor question matters more than people expect — a ring disappears on your hand in a way a band never quite does. Great for sleep-first users, less useful mid-lift.

Least noticeable to wear overnight
Also requires a subscription
No blood pressure trend feature

Bottom line

The only one of the three that isn't billing you every month.

If you don't need Whoop's strain scoring or a ring on your finger, Hume Band 2.0 currently offers the strongest five-year value of the three — plus a feature neither competitor has yet.
