That gets you a year of what I feel is the best subscription tier. It's not only cheaper than the usual $239/year price, it's also even cheaper than the lowest tier subscription, which is still at its regular price of $199. WHOOP Peak - 12-Month Membership - 5.0 Health and Fitness Wearable $189.00 at Amazon $239.00 Save $50.00 Get Deal Get Deal $189.00 at Amazon $239.00 Save $50.00 Whoop is the screenless wearable that set the standard for screenless wearables; all the other smart bands are still playing catch-up. Technically you're only paying for the subscription, and getting the device for "free." The company offers three tiers: Whoop One with a 5.0 device, $199. This tier is not on sale.Whoop Peak with a 5.0 device, $189, normally $239. (This now a lower price than the bottom tier, Whoop One.) Peak is the subscription I'd recommend for pretty much everybody. Whoop Life with an MG device, $299, normally $359. To be honest, I don't think the extra cost is worth it. All you get is ECG functionality on the strap, and a blood pressure feature of dubious usefulness. Go with Peak.You can read my review of the Whoop 5.0/MG generation here. Whoop used to be the only screenless tracker; now it's one of many, but I'd argue it still has the best app and is worth the money if you want to nerd out about your sleep, exercise, and how they relate to each other. That said, we've had several smart bands enter the picture over the past year. I have some thoughts on the smart band market here, but there are only two that are widely available and that I can recommend: Whoop for the premium experience, and the Fitbit Air ($99 with an optional $9.99/month subscription) for a more minimalist approach. If you already have a Whoop device, including the old 4.0 device, there are some independent apps aiming to fill the gap and let you get data from your strap without a subscription. These apps are still under development (and occasional legal threats) but I find them promising. Looking for something else?
