Your cycle, finally read in context.

Your cycle, perimenopause, sleep, HRV and recovery are one connected system — but every app shows them apart. Sage + Stone reads them together and surfaces the patterns the single-tracker apps miss.

Five apps, zero answers

Your symptoms, your sleep, and your temperature live in different apps. None of them talk.

Your body doesn't experience your cycle, perimenopause or recovery in silos — so why should your data? Sage + Stone unifies symptoms, sleep, HRV, temperature and energy across every device into one timeline, so the pattern finally holds together. Informational only, not medical advice — talk to your doctor.

The differentiator · Cycle Readiness

Your readiness score that knows a luteal dip is supposed to happen.

Generic recovery apps panic when your HRV drops in the back half of your cycle — and ping you for something your body does every single month. If you log cycle data, Sage + Stone turns your recovery score into Cycle Readiness: the expected late-luteal HRV trough is treated as normal context, not a red flag. This is cycle context for recovery — never hormonal diagnosis, fertile-window prediction, or contraception guidance.

  • Expected dips stay quiet. A −12% HRV reading on cycle day 22 reads as normal for late luteal, so your score reflects context instead of a false alarm.
  • Phase from data, not symptoms. Cycle phase comes only from cycle data you log or sync from Apple Health — Stone never infers your phase from how you feel.
  • Recovery context only. Cycle Readiness supports how you train and rest. It is not a hormonal assessment or fertility tool — bring health questions to your provider.

Cycle Readiness appears only when cycle data is present · informational, not a medical device

Cycle + symptoms + biometrics

Log symptoms alongside sleep, HRV and temperature from every device — and see how each cycle phase actually shows up in your body.

Perimenopause signals

Track the slow shifts in temperature, sleep and HRV that mark perimenopause — across devices, over months, not single readings.

AI coach across your cycle

A daily, plain-language read that accounts for where you are in your cycle — so advice fits your body, not a generic average.

Recovery & energy

See how recovery and energy track your cycle and sleep, with early-warning when your baseline drifts. Informational, not a diagnosis.

What the pattern looks like

The signal that finally made sense of it.

Different bodies, different barriers — one timeline that reads them together. The cards below are clearly-labeled illustrative samples, not real testimonials.

Sample

Perimenopause

The night-temperature and sleep trend lining up across months was the first time my perimenopause picture held still long enough to bring to my doctor.

[Dana, 48]

Sample

PCOS

Seeing my HRV and sleep next to my logged cycle data — instead of in five apps — finally showed me a pattern worth talking through with my provider.

[Renee, 31]

Sample

Post-GLP-1

As my energy shifted, the unified resting-heart-rate and recovery trend gave me one honest read instead of conflicting numbers.

[Priya, 42]

Sample

Postpartum

The Pattern Deviation note flagged when my own baseline drifted — a nudge to rest that I'd never have given myself in those first months.

[Maya, 34]

Sample

Poor sleep

Watching sleep quality feed my recovery score week over week showed me which nights actually mattered for how I felt.

[Hannah, 29]

Sample

Perimenopause

Cycle Readiness not panicking over my luteal HRV dip meant I stopped second-guessing a normal monthly pattern.

[Linda, 51]
