WHOOP is wading deeper into women’s health, and this time it’s teaming up with the one birth control app the FDA has actually cleared. As of 4 August 2026, WHOOP has folded Natural Cycles° — the only FDA-cleared, hormone-free birth control app — into its membership, and it’s throwing in a 12-month subscription for eligible new Natural Cycles users at no extra cost.
That’s a tidy perk, considering Natural Cycles normally runs US$149.99 per year in the US. But the more interesting part is what happens on your wrist.
Natural Cycles works by tracking your body’s subtle temperature shifts to identify fertile and non-fertile days. Traditionally that meant a basal thermometer and a groggy measurement first thing every morning — reliable, but a chore. WHOOP sidesteps that entirely.
If you own a compatible WHOOP device, the band can now automatically share your overnight skin temperature directly with the Natural Cycles app. No thermometer under the tongue, no manual logging, no remembering to do it before you’ve even opened your eyes. Your sleep-tracking hardware quietly does the work while you’re unconscious, then hands the data off.
It’s a smart bit of platform thinking. WHOOP already lives on your wrist 24/7 harvesting recovery, sleep and physiological metrics, so temperature is a natural extension rather than a bolt-on. Feeding that continuous overnight signal into an algorithm designed to read your cycle removes one of the biggest friction points in temperature-based contraception: consistency. Miss a morning reading and the model gets fuzzier; let a wearable handle it and you get a steadier stream of data.
A few things worth keeping straight:
- What it is: a service integration and membership perk, not a new gadget or a firmware feature you buy separately.
- Who gets the free year: eligible new Natural Cycles users.
- What the hardware does: compatible WHOOP devices auto-share overnight skin temperature with the NC° app.
- The catch: you’ll need one of those compatible WHOOP devices for the automatic sharing to work.
For WHOOP, this is another step in positioning itself as more than a fitness recovery tracker. Women’s health has become a genuine battleground in the wearables space, and pairing continuous physiological monitoring with an FDA-cleared contraception app is about as concrete a use case as you can offer. It’s not another vague wellness score — it’s a specific, clinically recognised function.
Whether you’re already deep in the WHOOP ecosystem or eyeing the platform for exactly this kind of feature, the pitch is straightforward: let the band you’re already wearing overnight do the measuring, and skip the thermometer entirely.
