Natural Cycles Pricing: What You Get and What You Don't

Natural Cycles Pricing Tiers

Hidden Costs You Won't See on the Pricing Page

• ⚠ App is designed for fertility and ovulation tracking — perimenopause use case is unsupported
• ⚠ No perimenopause-specific symptom logging (hot flashes, brain fog, mood, night sweats)
• ⚠ No doctor report export for gynecology appointments
• ⚠ Algorithm accuracy degrades as cycles become irregular in perimenopause

What Natural Cycles Charges

Natural Cycles has two standard subscription options: $13.99/month or $106.99/year. The annual plan works out to roughly $8.92/month. Thermometer bundles add hardware cost on top of the annual subscription.

There is no free tier.

What the Subscription Is For

Natural Cycles is FDA-cleared as a contraceptive device. The subscription pays for a basal body temperature algorithm designed to identify fertile and non-fertile days for women who want hormone-free birth control or are trying to conceive.

That is a specific and well-defined use case. The clinical validation, the FDA clearance, and the algorithm design are all oriented toward it.

The Perimenopause Problem

Perimenopause is a different use case entirely.

Natural Cycles’ algorithm assumes regular ovulatory cycles. It models fertile windows by detecting the temperature shift that follows ovulation. As perimenopause progresses, cycles lengthen, shorten, and skip. Ovulation becomes unpredictable or absent. The temperature patterns the algorithm relies on stop following the model.

The FDA clearance does not apply to perimenopause use. Natural Cycles does not claim it does.

More practically: the app does not track the symptoms that define perimenopause daily life. There is no logging for hot flashes, night sweats, brain fog, mood changes, joint pain, or irregular bleeding patterns. The logging interface is built around temperature and cycle data for fertility purposes.

What Horiva Costs Instead

Horiva costs $9/month for Essential — less than Natural Cycles’ monthly plan and comparable to the annual rate.

Horiva is built specifically for perimenopause. The 40+ symptom library covers the full range of symptoms women experience during the transition. The cycle tracking handles irregular, skipped, and unpredictably spaced cycles. The doctor report generates a structured PDF for provider appointments.

At Natural Cycles’ $13.99/month price, you are paying for fertility tracking that degrades in relevance as perimenopause advances. Horiva’s $9/month is for a product designed for where you are now.
