Your record remains the source.
Period starts, symptoms and signals stay marked as observations. Missing days remain missing.

A PRIVATE CYCLE JOURNAL THAT SHOWS ITS WORK
Your cycle isnot a deadline.
A private wellness journal that makes room for variation. It is not healthcare or medical advice and is not intended for diagnosis, treatment, conception planning or contraception. Mama Bloom keeps the range, evidence, uncertainty and corrections attached, calculated on your iPhone without a Mama Bloom account, ads or third-party tracking.
- Cycle record stays local
- No Mama Bloom account
- No ads or ad profile
- No third-party analytics
- No health-data backend

A DIFFERENT KIND OF CYCLE APP
A date is easy.
An honest range is useful.
Bodies do not move in perfect circles. The Living Loom turns what you actually record into a changing portrait—without hiding the gaps or converting a possibility into a promise.
THE LIVING LOOM
An estimate with its seams left visible.
Most trackers hand you one confident-looking date. Mama Bloom preserves what your record can actually support: a weighted range, a wider possibility, and a receipt for the method behind it.
Probability is shown as a range.
Variation widens the answer. A forecast never silently becomes an observed event.
Every change keeps a trace.
Correct an entry without erasing that it changed. Open the evidence receipt whenever you need it.
THE RECORD, IN MOTION
The Loom becomes the interface.
Scroll through one observation as it becomes a range, an evidence receipt and a personal pattern.
01OBSERVE
Nothing is assumed.
A new log begins empty. Flow, pain, sleep, mood, temperature and other body observations become part of the record only when you place them there.
Explicit input · visible source02RANGE
Uncertainty stays visible.
Mama Bloom shows a most-likely period range and the wider possibility your record can support. Variation widens the answer; it never becomes false precision.
Observed and estimated remain separate03EVIDENCE
Open the receipt.
Inspect recorded starts, intervals, exclusions, coverage and the method version behind a forecast. Corrections keep a trace instead of rewriting history.
Reviewable · correctable · versioned04UNDERSTAND
Your pattern, with its limits.
Personal comparisons describe what appears together in your own record. The Learn library gives context without turning correlation into diagnosis or prediction into certainty.
Personal, descriptive, never causalMORE THAN A CALENDAR
A private studio for a changing record.
Quick, explicit logging
Flow, pain, sleep, mood, LH, mucus, basal temperature, notes and more—with no value selected for you.
Observations without interpretation
LH tests, temperature and mucus notes stay exactly as you logged them—dated observations in your own record, never a fertility status, score or conclusion.
Apple Health, by permission
Choose individual Health categories. Imported wrist temperature remains distinct from basal temperature.
Apple Watch, without oversharing
See an uncertainty-aware glance and place quick observations into the protected iPhone record.
Private reports you author
Choose what belongs in a reflection or appointment PDF. Sensitive categories can stay out.
Available in six languages
English, German, Spanish, French, Russian and Japanese—with locale-aware dates, decimals and typography.
Discreet widgets, by consent
The default is simply “Open Mama Bloom.” A vague range and quick-action labels appear only when you enable them separately.
Shortcuts that protect the hand-off
Siri, Spotlight, Shortcuts and the Action button can open Today, Log or Reports—without speaking cycle values or silently saving an observation.

PRIVATE BY ARCHITECTURE
Your cycle record is not collected by Mama Bloom.
The app stores what you enter because a journal cannot work without a record. That record stays in protected local app storage: Mama Bloom does not receive it. There is no Mama Bloom account, ad or advertising profile, third-party analytics or tracking, developer cloud sync, or Mama Bloom health-data backend.

Keep Your Record Yours

Progress + reflection · stored on this deviceSix-language editorial boundary
The interface and guidance are localized in English, German, Spanish, French, Russian and Japanese and informed by locale-specific regional public-health, care and privacy sources. They are not described as independently locally authored. Native editorial, subject-matter and legal review in every locale is not claimed. Opening an external source leaves Mama Bloom’s protected interface; the browser and destination can receive ordinary network metadata such as an IP address.
THE COMPLETE PRIVATE STUDIO
Learning joins the instruments that deepen with your record.
Compare complete cycles, investigate two observed signals, review how the record changed, and author a private report with only the observations you choose.
- Three Private Editions · 11 genuinely new chapters
- Cycle-to-cycle editions and Pattern Loom comparisons
- Coverage, correction and source-aware observation review

BEFORE YOU TRY IT
Clear answers, including the limits.
Is Mama Bloom healthcare or a medical device?
Mama Bloom is designed and marketed only as a private period and cycle journal and personal wellness tracker. It is not intended for diagnosis, treatment or another medical purpose, and it does not provide healthcare or medical advice. Its estimates can be wrong and are never a substitute for qualified care.
Is Mama Bloom a period tracker?
Yes. Mama Bloom records period starts, bleeding context and other observations, then presents a most-likely range and a wider possible range. It keeps predictions visually separate from observations.
Does Mama Bloom collect my cycle record?
No. The app must store what you enter in order to work, but Mama Bloom does not receive or collect that cycle record. Its working archive and calculations stay in protected local app storage on your iPhone; the paired Watch can hold a limited snapshot and queued quick logs. There is no Mama Bloom account or health-data backend.
Does Mama Bloom use ads, tracking or third-party analytics?
No. The current app has no ads, advertising profile, third-party analytics or tracking SDK, and no developer cloud sync. This website also has no analytics or tracking scripts and sets no analytics or advertising cookies. Hosting and security systems still process ordinary request data needed to serve and protect the site.
Can widgets, Siri or Shortcuts reveal cycle details?
Not by default. Widgets begin with only “Open Mama Bloom.” A broad range and quick-action labels are separate opt-ins. Siri, Spotlight and Shortcuts open the protected app to continue; they do not speak cycle values or save a sensitive observation in the background.
What are private quality diagnostics?
If you explicitly enable them, Apple MetricKit crash, hang, energy and performance reports are scrubbed and retained locally in protected app storage. They are separate from your cycle record, are not uploaded to an analytics backend, and leave the device only when you deliberately export and send them.
Does Mama Bloom show a fertile window or ovulation days?
No. Mama Bloom does not show fertile-window or ovulation estimates. You can record LH tests, temperature and cervical-mucus observations as dated entries for your own record; Mama Bloom stores them exactly as logged and never combines them into a fertility status, ovulation conclusion or timing advice. Do not use Mama Bloom for conception planning or contraception.
What works on Apple Watch?
The Watch companion shows a privacy-sensitive forecast glance and supports quick logging for flow, pain, sleep and mood. The full evidence record and corrections remain on iPhone.
What is included without a subscription?
Core logging, complete history, period ranges, evidence receipts, the foundation Learn library, Apple Health access, app lock, safety guidance, export and deletion remain available without a subscription.
What does Private Edition add to Learn?
Three Private Editions add 11 genuinely new guided chapters: Read Your Range, Compose a Care Story and Keep Your Record Yours. Each has original commissioned artwork, a deeper synthesis and a private reflection prompt. Progress and reflections remain local on your device. Core safety guidance and the foundation library remain free.
