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 --- FREE vs PREMIUM --- Free: - Track up to 5 symptoms - Full logging and history - 7-day trends - Daily reminders - CSV export Premium ($4.99/month or $29.99/year): - Everything in Free - Unlimited symptoms - Unlimited history - Doctor-ready PDF reports with charts - Full trends (30/90/all-time) --- 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 the period you choose (30 or 90 days, 6 months, or everything), 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. Terms of Use (EULA): https://ebb.bio/terms Privacy Policy: https://ebb.bio/privacy

About

Truly Simple Symptom Log

Read full description

Truly Simple Symptom Log is built around a single conviction: health tracking should take seconds, not minutes. Most symptom trackers are overbuilt and cluttered with complicated graphs, gamification, mandatory onboarding, and subscriptions that make the act of recording how you feel a chore. This app strips all of that away. It features a calm, minimal, one-screen logging interface that feels closer to a personal journal than a medical tool. It’s perfect for people with chronic conditions, people exploring cause-and-effect with their health, or anyone who just wants a friction-free way to log their mood and symptoms and then move on with their day. There's an in-app purchase that allows you to lock the app and export your data, but all core features are available in the free version and can be used for free as long as you like. Features: • One-screen logging: Record your mood, symptoms, potential causes, and notes on a single page. No tabs or multi-step wizards. • Heatmap calendar: A color-coded monthly data view gives you an instant visual summary of how you've been feeling over time, so patterns become obvious at a glance. • Accessible by design: Enlarged, comfortable touch targets prevent mis-taps when you're not feeling well. Fully optimized for VoiceOver screen readers and scalable dynamic text for low vision. • iCloud Sync: Logs sync silently and automatically across your Mac, iPhone, and iPad. Status indicators let you know your data is secure at a glance. • Free core features: All core logging is completely free. A single one-time, lifetime purchase unlocks optional data exports and a biometric privacy lock.
