Buy the Polar Loop if you want a training band with Nightly Recharge and no subscription. Buy the Hume Band 2.0 if you want a lighter longevity tracker with blood-pressure trends and a longer claimed battery. Both are screenless, both are pay-once, and both are trying to be the Whoop you do not rent. They are not aimed at the same morning. Polar talks about last night's recharge and today's training load. Hume talks about biological age, metabolic capacity and the direction of your blood pressure.
Polar against the strap it copies is Whoop vs Polar Loop. Hume against the cheaper pebble is Hume Band vs Fitbit Air.
Short verdict: Polar Loop at $199.99 if you train and you want Polar Flow's recovery tools without a fee. Hume Band 2.0 at $249 if blood-pressure trends and a 14-day claim matter more than workout heart rate. If you only wanted sleep and steps, the $99 Fitbit Air is the cheaper third option.

Polar Loop: the training band
The Loop is a screenless module on a knit band, about 29 grams, with Polar's Precision Prime optical sensor. Nightly Recharge, SleepWise and training load are the morning. There is no SpO2 and no skin-temperature sensor, which is the spec sheet showing the $199.99 price. Battery is up to about 8 days, water rating 30 metres, so a swim is in bounds. Polar Flow syncs to Apple Health and Health Connect. The app is the complaint: it was built for watch owners, and a screenless band wants a calmer morning than Flow usually offers. The optional Fitness Program at $8.99 a month is not required to see recovery.
Hume Band 2.0: the longevity pebble
Hume's Band 2.0 is the lighter object, about 8.6 grams, with a claimed 14-day battery. A Wareable travel test got past 9 days, which is still a lot of wrist for something this small. The pitch is trends: blood pressure direction, metabolic capacity, a health score, a biological age that moves with habits. Hume is explicit that these are not diagnoses. IP68 is splash and a shallow dunk, not pool lengths. Exercise tracking is the consistent knock: heart rate during training lags the big brands. If the band's job is the run, this is the wrong band. The full note is the Hume Band 2.0 review.
Who should buy which
- Polar Loop if you already think in training load, you swim, or you want Polar's recovery words without Whoop's invoice.
- Hume if you want the lightest band, blood-pressure trends, and you will forgive a soft workout heart rate.
- Fitbit Air if $99, AFib alerts and a mainstream sleep score are the actual brief. That page is Polar Loop vs Fitbit Air.
- Whoop only if you will follow the coach often enough to justify $199 a year. Otherwise you rented a worse deal than either of these.
Three years of ownership is the right sum. Loop about $200. Hume about $249, less on promotion. Whoop One about $597. The pay-once bands win the spreadsheet. They win the morning only if you will look at Nightly Recharge or Hume's trends and change something. A band you ignore is a $200 bracelet.
Frequently asked questions
Is the Polar Loop better than the Hume Band?
For training, yes. The Loop has the stronger workout heart-rate reputation, a 30 metre water rating, and Nightly Recharge aimed at athletes. Hume is better if you want a lighter band, a longer battery claim, and blood-pressure trends rather than a training dashboard.
Do Polar Loop or Hume need a subscription?
No for the core scores. Polar's Fitness Program is an optional $8.99 a month. Hume's AI coaching is an optional extra around $8.99 a month. Whoop's membership is not optional. That is the reason these two exist.
Which has the longer battery?
Hume claims up to 14 days and independent wear has cleared 9. Polar Loop is rated up to about 8 days. Both beat a daily smartwatch charge. Hume's advantage shrinks if you needed swim-proofing, which it does not have.
Can either replace an Apple Watch?
Not if you wanted notifications, GPS maps, payments or a screen during the workout. Both are recovery bands. Pair them with a phone, or with a watch you take off at night.
