Ebb: Chronic Illness Tracker

Ebb is the symptom tracker for when you're too tired for symptom trackers.

Log how you're feeling in under 30 seconds -- no fuss, no friction. Just tap your symptoms, rate each one 1 to 5, add a quick note if you want, and you're done. Every single day, in half a minute.

--- WHY EBB? ---

Most symptom apps are built for people who have energy. If you've got fibromyalgia, ME/CFS, lupus, EDS, POTS, or any chronic illness that robs you of energy and focus, you don't want to spend five minutes logging. You want to spend thirty seconds.

Ebb is designed around that reality. Brain fog friendly. Minimal taps. Nothing unnecessary.

--- WHAT YOU GET ---

• 30-second daily check-in: rate each symptom 1-5, one note, done
• Track any symptom: pain, fatigue, brain fog, nausea, sleep quality, mood, or your own
• 7-day trend view on your home screen: spot patterns at a glance
• Full history: scroll back through every logged day
• Trends charts: see how each symptom behaves over time
• Daily reminders: a gentle nudge at whatever time works for you
• Private by default: everything stays on your device

--- THE DOCTOR REPORT (Premium) ---

Ebb's PDF export was built for that appointment moment -- when your doctor asks how you've been and you can't remember. Generate a clean report covering any date range, with your symptoms, daily ratings, notes, and charts. Walk in prepared.

--- DESIGNED FOR REAL LIFE ---

If you have fibromyalgia, ME/CFS, lupus, EDS, POTS, Crohn's, or any condition with unpredictable flares, Ebb was built with you in mind. Not for people who want to quantify every biometric. For people who just want to remember how they felt, see if it's getting better or worse, and share that with their care team.

Track the ebb and flow of how you feel. That's it.
