A symptom tracker you can use through brain fog

Brain fog makes most health apps unusable at exactly the moment you need them. Multi-step forms, sliders, mood wheels, journaling prompts — each one asks for the focus and working memory that fog takes away. So the log goes empty on the worst days, which are the days that matter most.

Ebb takes the opposite approach: one screen, minimal taps. You tap your symptoms, rate each one 1 to 5, add a note if you want, and you're done. Thirty seconds on a good day. Still doable on a bad one.

Why bother tracking brain fog?

Fog is one of the hardest symptoms to describe to a doctor, and one of the easiest to under-report — by definition, you don't remember it well. A simple daily rating fixes both problems:

• Patterns become visible. Does the fog follow poor sleep? A flare? A medication change? A 1–5 rating charted over weeks shows connections you can't hold in your head.
• Appointments get easier. Instead of "it's been bad, I think?", you show a trend line. Ebb exports a doctor-ready PDF of the period you choose, trend charts included.
• Your own words survive. A one-line note on a foggy day ("couldn't finish sentences") says more later than memory ever will.

What "brain fog friendly" means in practice

• No decisions to make. Your symptom list is already there; you just rate it.
• Nothing to navigate. Logging lives on one screen, not behind menus.
• Missed days don't break anything. No streaks, no guilt, no catch-up screens.
• A gentle reminder at whatever time your brain works best.
• Private by default. Your health data stays on your device.

Fog rarely travels alone

Brain fog shows up with ME/CFS, fibromyalgia, POTS, long COVID, lupus, thyroid conditions, perimenopause, and as a side effect of many medications. Ebb doesn't ask for a diagnosis — you track whatever symptoms matter to you, named in your own words, alongside the fog.

Common questions

How do you rate something as vague as brain fog?

On a 1 to 5 scale, in the moment, without overthinking it. The number on any single day doesn't matter much — the shape over weeks is what tells you something.

Can I track brain fog alongside pain and fatigue?

Yes. The free tier covers up to 5 symptoms at once, so fog, fatigue, pain, sleep, and mood fit together.

Is Ebb free?

Yes. The free tier lets you track up to 5 symptoms with full daily logging, complete history, 7-day trends, a daily reminder, and CSV export. Premium ($4.99/month or $29.99/year) adds unlimited symptoms, full trend ranges, and doctor-ready PDF reports.

Will it remind me to log?

Yes, one daily notification at a time you choose. You can turn it off entirely.
