Rhythm

Neurodivergent women have been overlooked for too long. Rhythm is helping to change that.

Recognition of neurodiversity in women has increased significantly in recent years, with growing evidence suggesting that many women have historically been missed, misdiagnosed or diagnosed later in life because neurodivergence often presents differently and is more likely to be masked. At the same time, emerging research is highlighting the impact that hormonal fluctuations can have on neurodivergent women, influencing areas such as attention, executive functioning, emotional regulation, sensory sensitivities and overall wellbeing throughout the menstrual cycle. Despite this growing body of evidence, there are few tools designed specifically to help neurodivergent women understand these patterns in the context of their daily lives. Rhythm aims to bridge that gap by helping women better understand their changing energy and capacity, learn from the experiences of others, and access support from a community that understands their lived experience.

Penny Day, Chief Operating Officer of XR Therapeutics, is developing Rhythm to help neurodivergent women explore the relationship between hormones, emotional dysregulation, and attention in a single app. The aim is to help them understand their personal patterns, learn regulation strategies, and approach their experience with greater self-awareness. This would help women feel more in control, day to day, across the cycle.

“My vision for Rhythm is to help neurodivergent women better understand their own rhythm - connect the dots between hormones, attention and emotional regulation. By recognising patterns in their energy and capacity, they can make more informed decisions and communicate their needs more effectively.”

Rhythm will combine cycle tracking with mood, focus and energy logs, personalised insights, journalling prompts, educational content and timely reminders. Co-designed with neurodivergent women, it will go beyond tracking to help users recognise their patterns and feel understood throughout the cycle. The app will also offer self-care ideas, productivity and creative strategies, shared stories and community support grounded in lived experience.

Rhythm draws on Penny Day's technical expertise in clinical digital health, lived experience of AuDHD. While the platform will be supported by clinical advisors and informed by research, it is being built alongside neurodivergent women themselves. Content will combine professional expertise from mental health practitioners, wellbeing specialists, personal trainers, Pilates instructors, performance coaches and other experts, alongside the lived experiences, stories and insights of neurodivergent women. The aim is to create a resource that feels both evidence-informed and deeply relatable to the women it serves.
