Why this exists

Endometriosis is already hard enough. Your data should work for you — not sit unused.

Most apps ask you to log things, then leave you with a wall of numbers. Endometriosis Companion connects the dots in your own logs so recurring patterns become impossible to ignore.

01

You know something is changing — but explaining it to a doctor without clear evidence feels impossible.

02

You suspect food, cycle phase, movement or stress play a role — but connecting the dots is exhausting.

03

You want something that understands flare-ups, bad weeks and lived reality — not a streak-obsessed wellness app.

04

You care about privacy because this is not casual data. It is your pain, your cycle, your body.

Inside the app

Your daily logs. Clearer patterns over time.

No cluttered dashboards. No overwhelming medical language. Just what your own data is telling you.

What makes it different

Built around endometriosis realities — because your body deserves more than a generic period tracker.

Fertility apps were not designed for chronic pain, flare-ups, inflammation clues, fatigue, food reactions or appointment advocacy. This is.

01 · Symptom patterns

Understand when symptoms show up — and what tends to happen around them.

Track pain, fatigue, bloating, digestion, mood, food, medications, supplements and exercise. The app detects patterns across cycle phases, food categories, exercise types, days of the week, and the window around your period ending — surfacing clues that are impossible to spot manually.

Food & Symptoms

Bloating Pelvic pain Fatigue

02 · Food & phase interactions

See whether food effects change across your cycle.

Certain foods may affect you more in one phase than another. The app tests whether a food trigger you've identified is amplified in your luteal phase, follicular phase, or around your period — surfacing nuance that flat averages miss.

03 · Movement without guilt

Rest days count too. So does intensity.

Track exercise type, intensity and rest so you can learn which movement feels supportive — and when your body may need recovery. Yoga vs. HIIT. Low vs. high intensity. The app notices when these matter differently across your cycle.

04 · Calendar & history

Your whole cycle history, at a glance.

A horizontal calendar view shows every logged month — with bleeding flow colour, pain circles, and symptom indicators visible at a glance. Tap any day to see full detail, or open your history for a searchable log by cycle range.

05 · Notes & entry control

Add context. Exclude anomalies.

Log a free-text note on any entry — illness, travel, a one-off stressful day. Notes are only shared with the AI companion if you choose to use it. Unusual days can be excluded from pattern calculations so they don't skew your data.

06 · Basic or Pro

Pattern recognition is always on. AI is optional.

Automatic pattern recognition — food correlations, cycle timing, exercise impact, phase interactions — runs in the background on every plan (from $5/month). Companion Pro adds deeper AI insights that narrate your patterns in plain language for you and your specialist ($8/month). Both plans start with a 28-day free trial.

Why it feels different

Built for pattern recognition — not just symptom logging.

Privacy promise

Your health data will never be sold. Ever.

Your symptoms, cycle, pain, medications and food logs are deeply personal. Endometriosis Companion is built on the belief that this information should stay yours.

No advertising marketplace. No data broker model. No monetising your pain.

We will never sell your health data, build advertising profiles from your symptoms, or share your personal health patterns with third-party advertisers.

No creepy targeting.

Your data is used to help you understand your patterns — not to sell you things when you are vulnerable.

Plain-language trust.

No vague "partners may use data" language hiding the truth. The promise is simple: your data will not be sold. Ever.

What you may start noticing

When you log consistently, patterns that felt invisible start to emerge.

Endometriosis Companion is designed to surface patterns from your own logged data — pain, bloating, fatigue, food, movement and cycle phase — so the picture becomes clearer over time.

"My pain tends to rise before my period, not randomly."
"Bloating shows up more often after dairy during my luteal phase — not other times."
"Yoga days tend to have lower pain scores than HIIT days."
"Fatigue appears heavier in the days just after my period ends."
"My symptoms cluster more on certain days of the week — there's a pattern I hadn't spotted."
"My food and symptom tracker finally gives me clearer information for appointments."
The feeling we are building for

Less "am I imagining this?" More "my own data shows it clearly."

"I want to walk into appointments with something clearer than scattered memories."

Appointment confidence

"I do not need another app telling me to be perfect. I need one that understands flare-ups."

Real-life tracking

"My health data is not a marketing opportunity. It should stay mine."

Pattern recognition vs. AI insights — what's the difference?
Automatic pattern recognition runs in the background as you log — surfacing charts, cycle overlays, food trends, exercise correlations, phase interactions and flare windows without you doing anything extra. It's included in both plans. AI insights go a step further: written, plain-language summaries that connect the dots across your symptoms, food, cycle phase and time — the kind of narrative you can read yourself or hand to your specialist.
Questions before you start

Honest answers, no inflated promises.

Is this an endometriosis symptom tracker?

Yes — but it's built to be much more than that. Most symptom trackers give you a log. Endometriosis Companion connects your logs. It tracks pain, bloating, fatigue, mood, food, movement, energy and cycle phase together, then surfaces the patterns and correlations that emerge over time. The goal isn't just recording what happened — it's helping you actually understand it, and walk into appointments with something concrete to show your practitioner.

What's the difference between Basic and Pro?

Both plans include all tracking features and automatic pattern recognition — food correlations, exercise impact, phase interactions, cycle timing, day-of-week patterns, and more. Companion Pro adds the AI layer: written plain-language summaries of your patterns, the ability to ask Companion questions about your data, and up to 100 AI insights per month. If you want the patterns but not the AI, Basic at $5/month is the right fit. Your 28-day trial gives you full Pro access so you can decide after experiencing both.

What happens after my free trial?

After your 28-day trial, you'll automatically move to Companion Pro ($8/month) — so you can keep everything you've been using without any interruption. If you'd prefer Basic ($5/month) instead, you can switch any time during your trial from your account settings. Either way, you can cancel before your trial ends with no charge.

Is this medical advice?

No. Endometriosis Companion is for education, personal tracking and pattern awareness. It does not diagnose, treat or replace care from a qualified health professional.

Can I track food and symptoms together?

Yes. You can log food categories alongside symptoms so the app can surface possible food and symptom associations over time — including whether certain food effects are stronger in specific cycle phases. The app tracks same-day and next-day associations, and notes when confidence is low.

Will my health data be sold?

No. Your health data will never be sold. Ever.

Start privately

You have been tracking your body in your head for years. Let your logs do it instead.
