Liora vs. Clue (BioWink)
European science-backed menstrual cycle app vs. a perimenopause journal with Apple Health context
- Category: Period and cycle tracker
- HQ: Berlin, Germany
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.

Liora vs. Clue FAQ
Answers to common questions about switching, data privacy, and feature differences.
How does Liora perimenopause tracking differ from Clue Perimenopause?
Clue Perimenopause is an extension of its core menstrual cycle calendar. Liora is built for the menopause transition: whole check-ins, Field Notes with their evidence, read-only Apple Health readings in context, and equal choices for surgical, induced and no-period paths.
Can Liora replace my doctor consultation?
No. Liora provides observations for discussion, not medical advice, diagnosis or treatment. It helps you prepare for your doctor visit by putting your question and chosen records on one clear page.
