## What is Nuchronic?

Track your energy and symptoms in seconds. Take a clear record to your appointments.

Nuchronic is made for ME/CFS, long COVID and other chronic illnesses. It's quick to use on a bad day, calm to look at, and keeps everything on your phone.

CHECK IN WITH A FEW TAPS
• Energy, symptoms, PEM or crash, sleep, pain, brain fog and dizziness, each on a simple 0 to 4 scale
• Add up to four symptoms of your own
• "Same as yesterday" for the days when that's all you can manage
• Skip anything. A missed day is just blank, with no streaks and no nagging

SEE YOUR PATTERNS
• A year in pixels: a square for every day, shaded so a darker square always means a harder day
• Month summaries: days logged, average energy and symptoms, and PEM days
• Tap any day to view it or fill it in

PLAN FOR CRASHES
• Write your crash plan on a good day: warning signs, triggers, what helps, what to drop, how others can help and who to contact
• Crash mode shows your plan in large, calm text when thinking is hard

KEEP YOUR RECORDS TOGETHER
• Health summary: conditions, allergies, how your illness affects you and what helps at appointments
• Medications, including ones you've stopped
• Appointments, with questions to ask before and notes after
• Care contacts, one tap to call

UNDERSTAND PACING
Short, plain-English guides to pacing, boom and bust, PEM, finding your baseline, the energy envelope, preparing for appointments and making a crash plan, each with links to trusted sources.

NUCHRONIC PLUS
A one-off purchase, no subscription. Turn your records into a PDF for your doctor or clinic: health summary, medications, your questions, month by month, a daily log and your crash plan, in A4 or US Letter. Email it, print it or save it to Files.

MADE TO BE EASY ON YOU
• Dark design with a burnt orange accent, or choose your own tint
• Large tap targets, support for larger text and VoiceOver
• Works in portrait and landscape, and adapts to larger screens

PRIVATE BY DESIGN
Everything stays on your phone. No account, no tracking, no analytics, and nothing is sent anywhere. Export a backup whenever you like.

NOT MEDICAL ADVICE
Nuchronic helps you keep your own records and plans. It doesn't diagnose, treat or tell you what to do. If your symptoms change or worry you, contact your doctor. In an emergency, contact your local emergency services.
