Celsia perimenopause tracker review: Apple Watch, Apple Health, and a one-page PDF

Quick answer: Celsia: Perimenopause Tracker is an iPhone and Apple Watch app from Apex Made, LLC (track ID 6816548220). It came out on October 5, 2026, was on version 1.0.1 (updated October 23), and had 1 rating when we checked on October 27, 2026. Its pitch is that your Watch already collects a lot of what matters at night. With permission, Celsia reads sleep, heart rate variability, resting and overnight heart rate, and wrist temperature from Apple Health and compares each night with your own usual range. You log symptoms with one tap, including from the Lock Screen, Control Center, Siri, or the Watch, and it builds a free one-page PDF for your provider. There is no account. Celsia Pro ($39.99 a year with a 14-day trial, or $6.99 a month) adds longer trends, pattern cards, and a fuller report. It needs iOS 26 or later. Stabilize is the broader choice if you also want bleeding, mood, refill problems, side-effect concerns, and clinician questions in one menopause timeline.

Engagement note (sticky CTA, Oct 27 new review): Looking at Celsia next to other perimenopause trackers? Whatever records your nights, it helps to keep the rest of the story (symptoms, bleeding, HRT context, and your questions) in one place before a visit. The Stabilize button below starts a private appointment-prep timeline. This is a fair comparison for tracking, not an endorsement or medical advice.

Who this Celsia review is for

This page is for women age 40-65 in perimenopause or menopause who came across Celsia on the App Store and want to know what it actually does, what it costs, and what to write down before seeing a clinician.

What this page is / isn't

• Is: a fair review based on the public App Store listing for Celsia as we read it on October 27, 2026, plus a tracking and appointment-prep checklist.
• Isn't: an endorsement, a privacy audit, a hands-on test of every screen, or medical advice. It won't tell you which therapy to use, how to use it, or when to change it.

Listings, prices, and privacy labels change. Check the current App Store page before you install or enter health notes.

What the public App Store listing says

We compared Apple's iTunes lookup with the US App Store page on October 27, 2026 (version 1.0.1, iPhone and Apple Watch, iOS 26 or later, free download with in-app purchases).

Nights from Apple Health

• with your permission, it reads sleep, HRV, resting and overnight heart rate, and wrist temperature
• each night is compared with your own usual range, not with other people
• the Today screen sums up last night in one sentence and marks anything outside your usual

Logging

• one tap for a hot flash, night sweats, or any of 20+ symptoms; press and hold to set strength and time
• logging from the Lock Screen, Control Center, Siri, or the Apple Watch app without opening the iPhone app
• symptoms and bleeding you log are written to Apple Health where a matching type exists, and symptoms already in Apple Health count too
• bleeding and spotting, with days since your last bleed and no predictions

Therapy log (documentation only)

• the listing covers estrogen in several forms, progesterone, vaginal estrogen, rings, IUDs, nonhormonal treatments, and custom entries
• reminders with Taken, Snooze, and Skip buttons, and every therapy change marked on your timeline
• the listing also says reminders can suggest a next patch site. We mention that only because it's in the listing; questions about placement belong with your clinician or pharmacist

Report and trends

• a free one-page PDF with current therapy and how often it was taken, symptoms per week, nights against your usual, bleeding, and your questions
• an optional reminder the evening before an appointment you've entered
• free trends cover four weeks. Celsia Pro extends that to 12 weeks or a year and adds pattern cards with a "Why am I seeing this?" note

Celsia Pro

• $39.99 a year with a 14-day free trial, or $6.99 a month, per the App Store purchase list
• the listing says logging, the therapy log, reminders, widgets, the Watch app, the one-page report, and full export stay free

The listing says Celsia "does not diagnose," and that it does not recommend treatments. That's the right frame, and it's how this page treats the therapy log and its "what changed after your latest change" view.

Privacy label check

The description says there's no account, no sign-in, no analytics, no ads, no tracking, and no third-party SDKs, and that Apple Health data never leaves the iPhone. Apple's privacy section (reported by the developer, not checked by Apple) says Data Not Collected. That's about as clean as these labels get. Two things still apply: anything Celsia writes into Apple Health then follows your Apple Health and iCloud settings, and labels can change with updates, so look again after a big release.

Celsia vs Stabilize: a fair comparison

• Passive night data: Celsia's main strength is reading Watch data and showing each night against your own baseline. If night sweats and broken sleep are your biggest issue and you already wear a Watch, that's useful.
• Fast logging: Lock Screen, Control Center, Siri, and Watch logging make it easy to catch symptoms as they happen.
• Report: the one-page provider PDF is free, which isn't true of many apps in this category. Preview it before a visit and make sure it answers "how often, how bad, and what else changed?"
• Breadth: Celsia focuses on symptoms, nights, bleeding, and therapy. Stabilize is broader if you also want mood, anxiety, digestive or urinary symptoms, refill gaps, pharmacy friction, and side-effect concerns in the same record.
• Treatment charts: Celsia shows what changed after your latest therapy change. Treat that as a record to discuss, not proof that a therapy is or isn't working. Many things move sleep and symptoms from week to week.
• Device needs: Celsia needs iOS 26 or later, and the night features depend on wearing an Apple Watch. Check your phone's iOS version before you plan around it.
• Track record: Celsia is a few weeks old with one rating. New apps can improve fast, but there aren't public reviews yet to show how reliable it is.

What to track during a one-week Celsia test

If you try it, keep notes on the app as well as your symptoms:

• hot flashes and night sweats: how many, how strong, and what time
• nights: whether the "outside your usual" flags match how you actually felt the next day
• sleep, mood, brain fog, joint pain, palpitations, or headaches, including anything the default list misses
• bleeding or spotting and the days since your last bleed, if that applies to your stage
• HRT or nonhormonal context as documentation only: product name, form, and the date it started or changed, exactly as your clinician or the label already directs
• missed reminders, skin irritation, or refill gaps worth mentioning
• the questions you want answered at your next visit
• app notes: what the free PDF shows, which views lock after four weeks, and whether Apple Health write-back behaves the way you expect

A clinician-ready summary from any tracker

A short, factual summary usually helps more than pages of charts:

• "Over the last four weeks I logged [X] hot flashes and [Y] nights with night sweats."
• "My sleep was outside my usual range on [N] nights, mostly in the weeks when [pattern]."
• "My therapy context was [product, form], started or last changed on [date]. I haven't changed anything because of the app."
• "Bleeding or spotting: [dates, or none]."
• "My questions are about [symptom pattern, side-effect concern, or what needs follow-up]."

How to use Stabilize for this

1. Keep Celsia for Watch-based night data and quick logging if you like it, or log symptoms directly in Stabilize.
2. In Stabilize, keep hot flashes, night sweats, sleep, mood, brain fog, bleeding, and HRT or nonhormonal context in one private timeline.
3. Add refill gaps, pharmacy problems, and side-effect concerns as dated notes so you don't have to remember them later.
4. Write your clinician questions down as they come up.
5. Before the visit, review the summary and bring patterns and questions rather than conclusions.

When Stabilize may be the better fit

Celsia may be all you need if you wear an Apple Watch, mainly care about nights and hot flashes, and want a free one-page report. Stabilize is usually the better fit if you want one menopause timeline that holds symptoms, bleeding, mood, HRT context, refill friction, side-effect concerns, and clinician questions together for follow-up visits.

FAQ

Is the Celsia provider PDF free?

Yes, per the listing. The one-page report is free. Celsia Pro adds a longer report with a day-by-day grid and unlimited report history. Check the current App Store terms before you count on it for a visit.

Do I need an Apple Watch to use Celsia?

No, you can log on the iPhone alone. The night comparisons rely on data from Apple Health, which in practice usually comes from a Watch.

Should Celsia's reminders or therapy-change view change how I use my therapy?

No. Use them as a record of what you already do as directed. Questions about timing, placement, products, or changes belong with your clinician or pharmacist.

Can Celsia or Stabilize diagnose perimenopause?

No. Apps, charts, and PDFs organize what you notice so you can talk it through with a clinician. They shouldn't diagnose menopause, interpret labs, or guide medication decisions.

Is this page for TRT or gender-affirming hormone therapy?

No. This page is about perimenopause and menopause tracking for women age 40-65.
