Project: Nuchronic - Energy & Symptom Tracker

Nuchronic helps people with ME/CFS, long COVID and other chronic illnesses track their energy and symptoms in seconds, keep a crash plan and health records together, and take a clear PDF record to appointments. It’s the Nuchronic printables as an app, and a companion to Nuchronic.uk.

Highlights

• A daily check-in in a few taps: energy, symptoms, PEM or crash, sleep, pain, brain fog, dizziness and up to four symptoms of your own, on simple 0 to 4 scales.
• A year in pixels and month summaries, shaded so a darker square always means a harder day.
• A crash plan written on a good day, and crash mode to show it in large, calm text on a bad one.
• Health summary, medications, appointments and care contacts in one place, plus short guides to pacing and PEM.
• Nuchronic Plus, a one-off purchase: turn your records into a PDF for your doctor or clinic, in A4 or US Letter.
• Built with SwiftUI for iPhone and iPad, dark by design, with custom tint controls and a Liquid Glass icon.
• Offline-first: everything stays on the device, with no account, analytics or cloud syncing. It records and shows what you enter, and isn’t medical advice.
• App Privacy Policy.
