Liora vs. Flo (Flo Health)
Mass-market period and ovulation calendar vs. a journal built for perimenopause and menopause
- Category: Period and cycle tracker
- HQ: London, United Kingdom
What changed in Liora since September 18?
These are the capabilities in the released iPhone app. Liora is our app; this is a product update, not an independent ranking or a claim that other apps lack these features.
Whole check-ins, at the time they happened
Choose from 47 symptoms, rate each from 1 to 5 and add one note, or record No symptoms to report. Keep up to five priorities first. Record several check-ins a day, now or later, with travel time zones and approximate periods preserved. Interrupted drafts are kept, and check-ins save offline before syncing.
A Journal you can correct
Browse a timeline, calendar and day details, including records from earlier app versions. Correct or delete a whole check-in. Conflicting edits ask for review rather than silently replacing another edit. Daily factors are separate records of context such as caffeine, alcohol and travel.
Field Notes with an inspectable history
See the period, dated evidence and limits behind an observation. Sparse records stay sparse and unrecorded days stay unknown. Corrections and source deletions can revise or withdraw a finding. Dismiss a note from Check-in while keeping it in Insights. Apple Health access is read-only: sleep duration, daily-average HRV, steps, active energy and weight.
Treatments and stage context
Record treatments, supplements and lifestyle changes with start and stop dates. With enough recorded days, compare the 60 days before a start with records since; these are observations, not treatment effects. The Horizon map supports natural cycles, surgical and induced menopause, irregular cycles and no periods. Period tracking is optional.
Sleep questions with separate choices
Choose saved check-ins, Apple Health sleep readings, individual private notes and AI wording separately for each question. AI wording starts off. If enabled, your question, permitted evidence, chosen notes and approved summary are sent to Anthropic; Liora does not add your name or email. Review, edit or remove the saved summary. Medication, diagnosis and urgent messages receive fixed safety guidance.
Appointment prep and account controls
Write your clinician question, choose up to three records, decide which notes and optional context to include, then preview a one-page PDF before sharing. Profile includes reminders, appearance, data export and account deletion. Larger text, VoiceOver labels and Reduce Motion are supported.
Field Note and Baseline Reflection wording uses AI services on derived summaries. The per-question AI choice above applies specifically to Ask about your sleep. Read our privacy policy for processing and retention details.

Where each platform excels
An honest comparison grounded in user workflows, clinical architecture, and verified product capabilities.
Where Liora stands out
Built from day one for the menopause transition
Flo was engineered for regular 28-day reproductive cycles. Its perimenopause mode is a recent addition to an app fundamentally designed around ovulation and pregnancy. Liora is a journal built for perimenopause and menopause.
No third-party ads, data never sold
Liora is a direct subscription. It never sells your data, never shares it with advertisers, and has no third-party ads or advertising trackers.
Apple Health readings beside your records
With your permission, Liora reads sleep and heart-rate variability from Apple Health and shows them beside your check-ins. Field Notes describe associations with their dates and limits, never causes.
Where Flo stands out
World-class fertility and ovulation algorithms
For women actively planning a pregnancy or tracking regular menstrual cycles, Flo offers refined algorithmic cycle predictions supported by a massive global dataset.
Conversational health assistant AI
Flo includes interactive conversational chat flows that guide users through reproductive health questions and symptoms.
Which product fits your specific situation?
Match your current healthcare needs and tracking preferences to the ideal companion.
| Your situation or need | Better choice | Why |
|---|---|---|
| You are experiencing erratic cycles, night sweats, and brain fog | Liora | Liora is built for perimenopause and shows Apple Health sleep readings beside your daily symptoms. |
| You are trying to conceive or predict exact ovulation days | Flo | Flo is an industry leader in fertility and ovulation tracking. |
| You have not had a period in 90 days and feel anxious | Liora | Liora is a journal, not a cycle predictor: you record bleeding when it happens and describe your stage yourself. |
| You want an app with no marketing trackers | Liora | Liora has no third-party ads or advertising trackers and never sells your data. |
Graduating from Flo to Liora
When your menstrual cycles become irregular or you enter perimenopause, cycle prediction calendars stop working. Liora gives you a journal for midlife symptoms, with Field Notes that show their evidence.
What changes
- You record bleeding when it happens rather than following predictions of when it should.
- You will track midlife symptoms like hot flashes, night sweats, sleep and mood instead of cervical mucus and ovulation.
- With your permission, Apple Health sleep and HRV readings appear beside your records.
What to plan for
- Liora does not predict ovulation or fertility. It is designed for perimenopause, menopause, and surgical or induced menopause.
- Onboarding asks for your stage and a first check-in, so you start with a record of today.
4 steps to transition
Note your historical cycle start dates from Flo if desired for clinical reference.
Install Liora on your iPhone and choose your stage.
Allow read-only Apple Health access if you want readings in context.

Liora vs. Flo FAQ
Answers to common questions about switching, data privacy, and feature differences.
Why does Flo perimenopause mode feel like regular cycle tracking?
Flo is architecturally designed around reproductive cycles and ovulation. Adding a perimenopause mode adapts existing cycle screens, but it can still prompt users for period predictions and pregnancy settings. Liora was built for perimenopause and menopause, and keeps surgical, induced and no-period paths visible.
Can Liora track my period if I still bleed?
Yes. Period, spotting and heavy bleeding are symptoms you can choose in a check-in, and Profile includes period tracking. Liora does not turn your bleeding into fertility predictions.
Is Liora safer for sensitive health data than Flo?
Liora has no third-party ads or advertising trackers and never sells your data. Records are encrypted in transit and at rest with access restricted to your account, and you can export your data or delete your account yourself in Profile.
