CycleWell: Period Tracker

CycleWell is a calm, private period tracker that learns your cycle and explains what is happening in your body — from your first logged period to pregnancy.

PERIOD & FERTILITY TRACKING • Log period start and end dates in a couple of taps • Predictions for your next period, ovulation day and fertile window • Confidence levels and a margin of error, so you know how sure a prediction is • Predictions improve automatically as you log more cycles • A clear calendar of logged days, predicted days, fertile window and ovulation

SYMPTOM, MOOD & SLEEP LOG • Track cramps, headaches, bloating, tender breasts and more • Daily mood, energy and private notes • Sleep duration and quality, plus basal body temperature • One-tap presets for the combinations you log most • A cycle-aligned heatmap that lines up repeating patterns day by day

INSIGHTS & PATTERNS • Average cycle length, regularity and cycles tracked • Interactive charts of symptoms, mood and sleep over time • Correlations that show which symptoms cluster in which phase • Export CSV, or a clean PDF report to bring to your doctor

PREGNANCY MODE • Switch off predictions and follow a due-date countdown instead • Fetal development week by week, from week 4 to week 40 • Trimester-specific guidance and milestones • Medication and supplement timeline • Pregnancy symptom tracking and correlations

LEARN ABOUT YOUR BODY • Articles and videos on reproductive health, surfaced for your current cycle phase or trimester • Save items for later and mark them as read • Short quizzes with key takeaways to reinforce what you learn • Recommendations based on your trimester and recent symptom and sleep patterns

PRIVATE BY DESIGN • Your health data is yours: export everything as a file, or permanently delete your account, at any time • Secure sign-in with email or Google • No selling of your personal data
