How the comparison works

Prices are snapshots from the linked sources. The price axis uses listed US prices, or the first year for WHOOP; where a model comes at several prices, it sits at the middle of the range. Battery points use published upper estimates for the device and about 60 days of dark reserve for Ray. Usage and test conditions vary. Weight points use the lightest listed configuration. Thickness and case volume use published case dimensions without the strap, in the smallest listed size; a ring's volume is the band itself at US size 10. A missing number leaves a device off that chart axis, while its full specs stay in the table.
