About
Cyelle is your cycle tracker for your period, ovulation, trying to conceive, and pregnancy – developed from real experience with cycles, ovulation tests, trying to conceive, pregnancy, and loss.
A cycle is more than a date on the calendar. Cyelle helps you understand your body better, recognize personal patterns, and make better sense of changes across multiple cycles.
TRACK YOUR CYCLE AND RECOGNIZE PATTERNS
Keep a clear view of your cycle and document the signals that matter to you. You see your current cycle day, your fertile window, and your estimated ovulation. With your entries, Cyelle can adapt estimates more and more closely to your personal rhythm.
You can record, among other things:
• Period and cycle day
• Days past ovulation
• Fertile window and ovulation estimate
• Basal body temperature and cervical mucus
• Symptoms, mood, and energy
OVULATION TESTS AND LH TREND
Cyelle supports different types of ovulation tests and displays your results clearly over time.
• Digital ovulation tests with different fertility levels
• Digital tests with low, high, and peak fertility
• Classic LH test strips with different line intensities
• History of your previous test results
With classic LH tests, you can record how strong your test line is. This creates a clear sequence of test results that can help you more easily recognize your LH surge and your possible peak window.
FOR TRYING TO CONCEIVE AND FERTILE DAYS
If you want to get pregnant, Cyelle brings the most important signals from your body together in one place. Cycle data, fertile days, ovulation tests, basal body temperature, and cervical mucus together create a clearer picture of your personal cycle. This helps you make better sense of your fertile phase and support your efforts to conceive in a more targeted way.
TRACK PREGNANCY – WITHOUT A NEW APP
If your cycle leads to pregnancy, Cyelle simply continues to support you.
No new app. No fresh start. No lost data.
You see your current week of pregnancy, can follow your baby's development, receive information suited to each stage, and have space for important appointments and personal milestones.
BY A WOMAN FOR WOMEN
Cyelle grew out of personal experience. From observing one's own cycle, waiting for ovulation, ovulation tests, and pregnancy tests. From trying to conceive, hope, pregnancy, and also loss.
That is why Cyelle is intentionally designed to feel calm, clear, and mature – without a cluttered design and without unnecessary cutesiness. An app for women who want to get to know their bodies better – whether they are observing their cycle, hoping for a baby, or already pregnant.
