A CLEARER HISTORY
See your rhythm at a glance.
Log flow and daily check-ins, then look back across a calm, readable calendar designed around the information you actually need.
YOUR BODY, YOUR RHYTHM
A gentler way to understand your body.
Rhyvelle is a private diary for cycles, optional pregnancy and menopause tracking, symptoms, moods, daily impact, and the patterns that make you, you. No ads. No account. No judgement.
Available now for iPhone · Free download
MADE FOR REAL CYCLES
Your health is not a countdown clock.
Bodies change. Cycles and life stages vary. Rhyvelle helps you notice your own patterns without presenting estimates as certainties—or turning a deeply personal experience into a stream of ads.
CHECK IN, YOUR WAY
Track more than dates.
Capture mood, symptoms, pain, notes, and optional health context without being forced to fill out a clinical form.
PREPARE FOR APPOINTMENTS
Take useful context with you.
Prepare questions and create a clinician report locally from only the diary information you choose.
RHYVELLE 1.0 & 1.1
More context when you need it.
Move from everyday tracking to appointment preparation without giving up control of your private health story.
OPTIONAL MENOPAUSE TRACKING
Follow symptoms, not predictions.
Switch to menopause-focused symptom and wellbeing check-ins while keeping mood, pain, impact, treatment, notes and bleeding available.
ADAPTIVE APPEARANCE
Comfortable in light or dark.
Rhyvelle follows your iPhone appearance setting with warm charcoal, rose and sage colours across the complete app.
OPTIONAL PREGNANCY TRACKING
A calmer view of each week.
Follow gestational week, trimester and estimated due-date progress, with pregnancy-specific check-ins and gentle baby-size comparisons.
CLINICIAN REPORTS
Bring the useful details.
Create a private PDF for a chosen date range, including the diary information you select. Reports are generated locally only when you ask.
APPOINTMENT PREPARATION
Remember what matters.
Record discussion priorities, questions for your clinician, and current medications or treatments before an appointment.
RICHER CHECK-INS
Notice life around the symptoms.
Optionally track daily-life impact and medication, treatment or relief alongside flow, mood, pain, symptoms and notes.
CAUTIOUS OBSERVATIONS
Patterns, without conclusions.
See careful observations from repeated entries. Rhyvelle never presents an association as a diagnosis, cause or certainty.
BACKUP & PROTECTION
Private, even when portable.
Protect the app with Face ID, use discreet local reminders, and create an AES-256 encrypted backup with a separate recovery key.
A SIMPLE PRIVACY PROMISE
Your health story belongs to you.
