A pain diary for the days nobody sees
Endometriosis pain has a way of being invisible exactly when it matters — it flares between appointments, gets averaged away by memory, and turns into "it's bad sometimes" in the exam room. Diagnosis famously takes years, and a big part of that gap is that the evidence lives in days nobody wrote down.
Ebb keeps the writing down cheap. You name what you want to track — pelvic pain, cramping, fatigue, bloating, whatever your endo actually does — rate each 1 to 5 with big taps, add a short note if you want, done in 30 seconds. On the worst days, that's all you have to give. No streaks, and missed days can be filled in later.

- "How often, and how bad?" gets a real answer. A dated chart of your ratings shows the pattern — which weeks, how severe, how long — instead of whatever your memory kept from the last month.
- Cyclical patterns become visible. Note your cycle day in the daily note and the record shows whether pain tracks your cycle, sits outside it, or both — a question your doctor will ask.
- Treatment changes get a before and after. Starting hormonal treatment, changing pain management, recovering from surgery — a daily log shows whether things actually moved, not whether it feels like they did.
What makes tracking sustainable
The tracker you'll still be using in six months is the one that costs the least energy. Ebb keeps the cost low on purpose:
- One screen, minimal taps. Usable mid-flare, in bed, with a heating pad.
- Your words, not a fixed template. Track what your endo actually does, not a generic checklist.
- Missed days don't break anything. No streaks, no guilt. Fill them in whenever.
- A gentle daily reminder at whatever time works for you.
- Private by default. Your health data stays on your device.

One honest note
Ebb is a diary, not a treatment tool, and it is not a cycle tracker — it doesn't predict periods or sync with cycle apps. It doesn't diagnose endometriosis and is not a substitute for your gynecologist or pain specialist. It just makes sure that when someone asks how the last few months went, you have an answer that isn't a guess.

What can I track for endometriosis?
Anything you name — commonly pelvic pain, cramping, fatigue, bloating, GI symptoms, pain with specific activities, and medication side effects. You rate each one 1 to 5 and can add one short note for the day, which is a good place to record where you are in your cycle.
Is Ebb a period or cycle tracking app?
No. Ebb doesn't track cycles, predict periods, or sync with cycle apps. It tracks daily symptom severity in your own words. Many people note their cycle day in the daily note so the PDF shows symptoms and cycle timing side by side, but if you want dedicated cycle features, a cycle app is the better tool — some people use both.
Can Ebb help me get taken seriously at appointments?
It can't promise how a doctor responds, but it changes what you walk in with. Instead of "the pain is bad some days," you bring a dated chart showing exactly which days, how severe, and what you noted. Premium exports a PDF of the period you choose — 30 or 90 days, 6 months, or your full history (see a real sample). Free exports your full history as CSV.
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.
