For people living with chronic illness
Chronical tracks your symptoms, food, labs and treatments — with an AI assistant that knows your history, so every answer is about you, not a search result.
iPhone and Android · Free during beta
Every feature feeds the same memory — so the more you track, the more useful Chronical becomes.
Ask anything about your condition and get answers grounded in your own diagnosis, medications, symptoms and labs — remembered across every conversation.
Snap a lab report and Chronical reads it — extracting the markers that matter for your condition, tracking them over time.
Before each appointment, get a brief of your recent symptoms, pain trends, lab changes and the questions worth asking — ready to share with your team.
Heart rate variability, resting heart rate, sleep and activity sync automatically, adding an objective layer to what you log.
Treatment reminders built around your own infusion or injection cycle, appointment nudges, and alerts when your symptoms show a pattern worth acting on.
Manage a child's condition alongside your own, with separate histories and an assistant that adapts its answers for parents and carers.
Symptoms, medications, procedures and lab panels are specific to your diagnosis. A CF patient and a Crohn's patient see different apps.
Chronical exists to help you manage your condition — not to monetise it.

We're inviting people living with chronic conditions to try Chronical early and tell us what would make it indispensable.
Chronical is a personal health tracking tool, not a medical device. It does not diagnose or treat any condition and is not a substitute for advice from your doctor or specialist team.
