Rithim App

Your ADHD forecast. Finally making sense. Rithim is the first app that gives you a daily, phase-aware read on what your ADHD brain is doing and why -- the way a weather app tells you what to wear before you walk out the door. Built by Clinical Psychologist Dr Deirdre Ryan, who has ADHD herself, Rithim connects the dots between your hormonal cycle and your symptoms so you can stop fighting your biology and start working with it. WHY YOUR ADHD CHANGES ACROSS YOUR CYCLE Estrogen directly modulates dopamine -- the neurotransmitter your ADHD brain is already short on. When estrogen rises (follicular phase), focus improves and medication works better. When it falls (luteal phase), everything gets harder: concentration drops, emotions run hot, and your to-do list becomes the enemy. This is not inconsistency. It is neurochemistry. Rithim tracks five key ADHD dimensions -- Focus, Energy, Mood, Anxiety, and Impulsivity -- against your cycle phase, so you can see your personal pattern emerge. WHAT RITHIM DOES Daily symptom tracking tied to your cycle phase Phase-aware insights that explain what your brain is doing and why 4 small, cycle-synced daily actions tailored to your current phase A full ADHD toolkit with strategies for medication, environment design, emotional regulation, body and movement, and clinical conversations Life stage support for perimenopause, menopause, postpartum, and irregular cycles RITHIM PLUS Unlock deeper understanding with Rithim Plus: Cycle Intelligence: After 10 check-ins, Rithim analyses your personal patterns and shows you exactly how your symptoms shift across your cycle Deep Neuroscience: Understand the receptor-level science behind why your brain does what it does, explained without the jargon Strategy Packs: Phase-specific action plans -- from "The Gentle Reset" (menstrual) to "The Power Window" (ovulation) Weekly Forecast: Know what is coming before it arrives Expert Briefings: In-depth articles by Dr Deirdre Ryan on topics like cycle-aware medication dosing and the ADHD-PMDD connection Clinician Reports: Generate professional clinical letters to help you communicate with your prescriber about cycle-aware treatment DESIGNED FOR PRIVACY Your health data is sensitive. Rithim stores it in a secure EU database (Frankfurt, Germany), encrypted at rest and in transit. No analytics SDKs. No advertising. No data selling. Your data is yours.

It is a clinical tool built from the neuroscience up, designed specifically for ADHD brains navigating hormonal fluctuations. Sharp, honest, and never patronising.
