Rythma vs. Health & Her for Perimenopause

Health & Her and Rythma are both built for midlife, but they are different kinds of product. Health & Her offers a free hormone-health tracker with a daily symptom log, a symptom checker the company says is based on the British Menopause Society's most common symptoms, and an evidence-based toolkit of habit-building exercises — pelvic floor training, meditation audios, interactive CBT, hydration reminders — alongside a personal task list and personalized recommendations; per its makers it is certified by the digital-health assessor ORCHA. It also sits inside a supplement business, so product recommendations are part of the experience. Rythma is narrower: it learns your personal symptom patterns, forecasts difficult days before they arrive, and generates a shareable doctor report. Pick Health & Her for a guided daily wellness routine; pick Rythma for prediction and appointment prep.

If you are choosing between these two, you are effectively choosing between "help me build better daily habits through this stage" and "help me see what is coming and prove it to my doctor." Both are legitimate, and they are not the same product.

We disclose that Rythma is our own app. Health & Her is described from its own published materials, with links so you can confirm current features and pricing yourself.

What both get right about perimenopause

Neither app assumes a 28-day cycle, which is the baseline requirement here.

Perimenopause usually begins in the mid- to late 40s and lasts about four years on average, sometimes as long as eight, according to the U.S. Office on Women's Health. During it, periods may run longer or shorter, heavier or lighter, skip months entirely, and you may not ovulate every cycle. The Cleveland Clinic describes hormone levels going up and down "like a rollercoaster" rather than declining smoothly.

The symptom range is also wide. In an international survey of more than 17,000 women across 158 countries analyzed by The Menopause Society, fatigue was the most reported symptom at 83%, ahead of irritability (80%), depressive mood (77%), and sleep problems (76%) — all outranking hot flashes at 71%. Both apps track well past bleeding, which a general period tracker often does not.

Health & Her — a free tracker wrapped in a wellness toolkit

Health & Her's app is free and, per the company, combines several things a plain tracker does not.

There is a daily log — a calendar for recording how you feel, any triggers, and periods if you are still having them. There is a symptom checker the company describes as based on the British Menopause Society's most commonly reported symptoms, covering hot flushes, night sweats, heavy periods, brain fog, and weight gain among others.

Around that sits the part that distinguishes it: an evidence-based toolkit of practical exercises intended to build daily habits, including pelvic floor training, meditation audio, interactive cognitive behavioural therapy, and hydration reminders. You can build a personal task list — a tailored plan reminding you to drink water, take supplements, do a monthly breast check, or listen to a sleep meditation. The company states the app is certified by ORCHA.

The honest caveat: Health & Her is also a supplement and product business, and the app surfaces personalized recommendations to its products and articles. That is disclosed rather than hidden, and plenty of people find the recommendations useful — but it is a different commercial model from a subscription tracker, and worth knowing when you read a recommendation. Confirm current features on the Health & Her app page.

Best for: women who want a free tracker plus a structured daily wellness routine, and who like being nudged into habits.

Trade-offs: wellness-toolkit focus rather than pattern prediction; product recommendations are part of the experience.

Rythma — prediction and a doctor-ready summary

Rythma is our app, so specifics. It is an iPhone app built for perimenopause from the start: it expects irregularity rather than assuming a monthly rhythm, and learns your individual symptom patterns as you log.

Its distinguishing feature is prediction of difficult days. Rather than only summarizing what happened, Rythma identifies your personal pattern and flags likely high-symptom stretches — fatigue, poor sleep, mood shifts, hot flashes, brain fog — before they arrive, so you can move a demanding meeting or protect a weekend.

The second piece is the doctor report: a structured, shareable summary of symptoms and trends over time, designed for appointments where midlife symptoms are easy to dismiss.

Best for: women whose cycles have become irregular, who want to anticipate hard days and bring evidence to a clinician.

Trade-offs: iPhone-only today; prediction improves the more you log, so early weeks are mostly data-gathering; and it does not offer guided exercises or a wellness curriculum. See the App Store listing.

Head-to-head: where they diverge

Doing vs. foreseeing. Health & Her's centre of gravity is action today: a task list, a meditation, a pelvic floor session. Rythma's is information about tomorrow. If your problem is "I know what I should be doing and I do not do it," a habit toolkit is the better fit. If your problem is "good days and terrible days arrive at random and I cannot plan anything," prediction is.

The appointment. Both give you a symptom history. Rythma packages it into a report intended to be handed over. Either way, logging is what lets you catch the bleeding changes the American College of Obstetricians and Gynecologists says warrant attention — very heavy bleeding (soaking a pad or tampon hourly for two or more hours), bleeding between periods or after sex, or cycles staying consistently closer than about 21 days.

Cost model. Health & Her's app is free, with a supplement business alongside it. Rythma is free to download with paid features; check the current App Store listing. Neither model is inherently better — they just point different directions.

Platform. Rythma is iPhone-only today. Check Health & Her's current availability if you are on Android.
