Living with CFS, ME, Long Covid, Fibromyalgia or POTS? CFS Tracker is a gentle, beautiful, offline diary built around the spoon theory — so you can pace your energy, spot crash patterns before they hit, and finally explain how you feel to the people who love you (and the doctors who treat you).

No streaks. No shame. No ads. Just a quiet sanctuary for your worst days and your best days alike.

WHY PEOPLE LOVE CFS TRACKER

• Daily energy / spoon budget — set how many spoons you have today, watch them tick down as you log activities. The app warns you before you go negative.
• One-tap symptom logging — fatigue, brain fog, pain, PEM (post-exertional malaise), heart rate, sleep quality, mood. Designed for foggy days when typing is hard.
• Crash & PEM tracker — log start time, severity, suspected trigger and symptoms. See your crash signature over time.
• Sleep log — bedtime, wake time, refreshment level, wake-ups. We surface the link between sleep and next-day energy.
• Activity & symptom libraries — extensive defaults, fully customisable. Add your own activities with their real spoon cost.
• Beautiful insights — trends in fatigue, mood, sleep and crashes. See what makes a good week, what triggers a bad one.
• Doctor-ready PDF reports — pick a date range, share or print a clean medical-style summary in seconds. Bring the data, not the guesswork.
• Medication tracker & reminders — schedule doses, log intakes, never wonder "did I take it?".
• Gentle journal & gratitude — a soft place to write on hard days.
• Goals — daily, weekly, monthly or one-off. Tiny wins. Real ones.
• Breathing exercises — Box, 4-7-8, gentle 4-6 patterns with a calming visual.

DESIGNED FOR CHRONIC ILLNESS

Most "habit" and "wellness" apps were built for athletes. They guilt you with streaks. They reward overdoing it. They don't understand PEM.

CFS Tracker was designed differently. It uses a low-contrast, soothing palette ("Ethereal Sanctuary") to be gentle on light-sensitive eyes. There are no streaks. No green-circle-shaming. Notifications are quiet, useful, and snoozable. The app respects your worst days as much as your best.

PRIVACY FIRST — ALWAYS

• 100% on-device. No accounts. No cloud. No analytics. No ads.
• Your diary lives in your phone, encrypted by Android. Nothing is uploaded.
• Export your data any time as a PDF report you control.
• Open about every permission we use and why.

WHO IS IT FOR?

• People with ME / CFS (myalgic encephalomyelitis / chronic fatigue syndrome)
• People with Long Covid / post-viral fatigue
• People with Fibromyalgia and POTS / dysautonomia
• Anyone navigating chronic fatigue, brain fog, or unpredictable crashes
• Carers and family who want to understand what their person is going through

A NOTE OF CARE

This app is not a medical device and is not a substitute for professional medical advice. It is a self-management diary. If your symptoms are severe or new, please contact a doctor.

We made this with love. We hope it makes your day a little softer.
