focyl - Women's ADHD × Cycle

Did you know that ADHD symptoms can shift markedly with the menstrual cycle? In the follicular phase, when estrogen rises, focus, memory, and decision-making tend to feel sharpest. This is the focus peak. In the late luteal phase, just before menstruation, executive function and emotional regulation often dip. Since 2024, peer-reviewed research on this connection has been published internationally. Yet existing apps have not addressed both at once. ADHD apps do not track the hormonal cycle. Menstrual cycle trackers do not track ADHD symptoms. focyl fills that gap. A purpose-built app that holds women's ADHD and the menstrual cycle in a single, integrated view. ▼ Three signature features 1. Luteal alert Three days before the late luteal phase begins, when symptoms tend to worsen, focyl gives you a gentle heads-up. Clear important tasks now. Hold off on new challenges. A small compass for the decisions ahead. 2. Focus peak forecast focyl predicts when your next follicular phase will arrive. Line up that important presentation, new project, or hard decision for the week your focus is sharpest, and put your ADHD traits to work. 3. Phase × domain heatmap Visualize 17 symptoms across 5 cycle phases × 5 symptom domains (executive function, attention, emotion, sensory experience, body). With three cycles of data, the relationship between hormonal tides and symptoms, a topic actively discussed in research, begins to surface within your own records. ▼ A PDF report that changes the conversation with your doctor Psychiatrists and gynecologists typically have 5 to 15 minutes per appointment. Conveying the tide of your symptoms in that short window is hard. focyl compiles your records into a single-page PDF that supports the conversation with your doctor. ▼ Privacy first, always Mental health and menstrual records are deeply sensitive personal information. focyl protects them thoroughly. - Every health record stays on-device only (symptoms, periods, notes, medication) - Zero health records sent to a server - Zero advertising SDKs - No crash reporting - No analytics - The only permission requested is notifications ▼ Grounded in research focyl's design is based on multiple peer-reviewed papers on the link between women's ADHD and the menstrual cycle. For citations, see the Research section at focyl.app. ▼ Important note focyl is not a medical device. It does not diagnose or treat. It is a tool to support self-observation and the conversation with your doctor. If your symptoms interfere with daily life, please consult a psychiatrist or gynecologist. Focus has a tide. Move with the moon. ▼ Subscription information focyl Pro is an auto-renewing subscription. focyl Pro Monthly: ¥580 / month (1-month free trial) focyl Pro Yearly: ¥4,800 / year (1-month free trial, about ¥400 / month equivalent) Payment will be charged to your Apple ID account at confirmation of purchase.
