What makes DarmKompass different

Leaving the house today? The honest read.

An honest daily read — based on your recent entries, not wellness promises. Low · Mid · High. Reasons visible.

Subway today?
Mid.

The app looks at your last day or two: stool, urgency, sleep, stress, what you ate. That becomes a simple read — not a guarantee, not an oracle.

If the data is thin we say so. If something is off we say that too.

Note: advisory and uncertain. Never a safety promise.

Everyday · Scenarios

Your day, yours again.

When your gut settles, the small moments settle too. Two glimpses of what that can feel like:

Calm morning on a sunlit balcony · sunrise, coffee, plants

A calm morning at home

Barefoot on the balcony, first coffee, no body-check running in your head. You know how today is — and that's enough.

Quiet tram ride at dawn · a mug in hand, looking out the window

Calm commute

Commuting without mapping the next bathroom. With your daily read in your pocket, the way there is just the way there again.

Features · everything included

Everything you need for honest symptom tracking.

Deterministic patterns instead of AI guessing. Every medical term explained, every recommendation derived from your own data.

Recommendations

Top-3 prioritised actions (red · amber · green) with a why-line from your own pattern. Every recommendation has a one-tap CTA.

Today's read

Combined daily score with 4 influencing factors (sleep, urgency, coffee, Bristol) — shows whether your gut looks stable today.

IBS-SSS (Francis 1997)

Weekly validated questionnaire, 0–500. 4 bands (remission / mild / moderate / severe). Accepted by clinicians.

Morning brief

Deterministic pattern briefing from your last 14 days: time window, weekday, trigger echo.

Medical glossary

14 terms (urgency, Bristol, VAS, trigger echo, red flags …) with short + detailed explanations.

Doctor PDF export

Clinical summary + daily overview + IBS-SSS history — print-ready for your visit.

Data export & deletion

JSON export anytime. Account deletion via 3-step dialog — real deletion within 24 h, not just "deactivated".

German & English

Every string bilingual. Switch language anytime, saved to your profile.

How it works

Three steps. One day.

From a 30-second entry to an exported 4-week report — a plain pipeline, not a coaching marathon.

What DarmKompass is not.

We build for a target group and are honest about what lies outside. Clear yes, clear no.

NOT · Out of scope

Not a diagnosis tool.

  • Not a medical device, not a treatment recommendation.
  • No emergency triage — for acute symptoms: doctor or emergency line.
  • No photo AI, no wearable hub, no affiliate shop.
  • No coaching. No lifestyle promises.
YES · In scope

Symptom companion for IBS.

  • Fast, structured logging — usable daily.
  • Understandable patterns with an honest daily read.
  • 2- or 4-week PDF for your next appointment.
  • „Can I leave the house today?" daily read.
  • Red-flag escalation if something stands out.

Dashboard (confidence · morning brief · top-3)Daily confidence (0–100) summarises your recent patterns. Morning brief gives a deterministic pattern briefing. Top-3 are the most actionable recommendations for today.
IBS-SSS weekly check (Francis 1997)Validated 5-question IBS severity score, per Francis et al. (Aliment Pharmacol Ther, 1997). Under 30 seconds, once per week recommended.
Trigger echo detectionAn “echo” shows when a trigger (e.g. morning coffee) was followed by symptoms multiple times within hours. Pure pattern recognition — no machine learning, every calculation traceable.
Back-dated entries (90 days)Enter symptoms, triggers and check-ins up to 90 days back. Useful to fill a gap or start with historical data.
Streak (Daylio style · 2 grace days)Counts consecutive days with at least one entry. In the rolling 30-day window, 2 “grace days” are allowed — missed days don't break the streak. Zero-guilt by design.
Personal norm (after 60 days)Once you've logged 60 days, we compute your personal averages (30-day window). You see Δ against your norm instead of absolute numbers — more meaningful than arbitrary benchmarks.
Year review (after 30 days)Spotify-Wrapped-style: your tracking data as 6–8 slides. Available once you've collected 30 days. Shareable card contains only metadata (day count, lessons) — no symptom data.
Academy certificate (on track completion)Finish all lessons of a track (e.g. IBS basics, nutrition, mindset) and receive a PDF certificate. Not a medical credential — an anchor for your own learning journey.
Cohort benchmarks (opt-in · k ≥ 50)Voluntary comparison of your aggregate values with users of your focus subtype. Only visible when ≥ 50 others are tracking the same subtype (k-anonymity). Withdraw consent anytime.
Daily web push remindersOne browser push per day at your chosen time. Works on desktop and mobile, offline-safe (delivers once back online).
JSON data exportExport all your entries as a machine-readable JSON file. For your own analyses, backups or migration. Your data, your call.
RangeHow far back the dashboard analysis looks. Free: 7 days. Premium: 14 / 28 / 56 / 90 / 180 / 365 days + custom ranges (e.g. “March 1 to April 14”).

Premium academy lessonsDeeper lessons: cycle phases, medication effects, dose windows, FODMAP details, microbiome. Free covers the introductory lessons of every track.
Doctor share link (secure, revocable)Time-limited link — your doctor opens it in a browser, no login needed. Revoke anytime (link stops working instantly). Perfect for second opinions or follow-ups.
Clinical analytics (Rome IV · IBS-SSS Δ)Rome IV subtype estimate (IBS-D / IBS-C / IBS-M / IBS-U), IBS-SSS curve with Δ vs. prior period, PPV alarm panel for red flags. Reads like a short doctor letter.
Pain VAS (0–100)Fine-grained visual analogue scale (0 = no pain, 100 = worst imaginable pain). Clinical standard and the basis for the real IBS-SSS pain score. Free uses a coarser 4-step scale.
Focus personalisation (KPI order)Set your main focus (urgency, stool or pain) — the dashboard puts the matching KPIs first; insights and morning brief are weighted accordingly.
Advanced reminders (weekdays / flare)Cadences beyond the daily push: weekdays only, or only on flare days (elevated symptom activity). Calm phases = calm app.
Heatmap history: months + yearsCalendar view of your history — each day colour-coded by severity. Premium opens months and years back. Free shows 7 days.
CSV data exportIn addition to JSON: a spreadsheet-friendly CSV file of all entries. For Excel, Sheets, R, or Python.
Premium supportPrioritised email responses: turnaround within business days (instead of the standard “as soon as possible”).

FAQ · common questions

Everything you want to know first.

We're honest about scope, price, and privacy. If something's missing, write to us.

What is DarmKompass and how is it different from a DiGA like Cara Care?
DarmKompass is a private IBS diary — not a medical device, not a DiGA. We don't offer a 12-week therapy program, no prescription-based insurance app, no diagnosis. In return: fast logging, deterministic patterns, a clean doctor PDF, and zero ads. If you want a prescribed treatment, a DiGA like Cara Care is a better fit — if you want honest tracking without a coaching program, we are.
Is DarmKompass free?
Yes. The free plan covers complete tracking — unlimited symptoms, triggers, check-ins, daily read, IBS-SSS weekly check, morning brief, streak, year review, academy certificate, JSON export, and one free doctor PDF. Free range: 7 days. No credit card, no trial trick. Premium (€2.99/month or €29.90/year) unlocks all ranges up to 365 days, unlimited doctor PDFs, the doctor share link, the clinical summary, and advanced reminders.
Where is my data stored?
In a private data space in the EU (Supabase, GDPR-compliant). Access only with your magic-link login. Zero trackers, no third-party analytics, no sale to ad networks. Everything encrypted — in transit and at rest.
How do I create a doctor report?
In three clicks: pick a range (2 or 4 weeks), start export, download PDF. The report contains symptom course, Bristol distribution, urgency peaks, possible triggers, and red-flag status — in a format any GP practice reads at a glance.
What is the Bristol stool scale?
A clinical 7-step scale (1 = hard, 7 = liquid), used by doctors worldwide. DarmKompass shows it inline while logging — with visual shapes so you find yours without looking it up. Every medical term (urgency, VAS, IBS-SSS …) has a tap-to-explain gloss.
Does DarmKompass auto-detect food triggers?
Deterministically, no AI black box. We show: "After short sleep, 78% of entries had higher urgency" — with the exact sample size. No recommendations from patterns no one can trace. When data is thin, we say so.
Can I export or delete my data?
Anytime. JSON export (complete dataset) in Free, PDF doctor report in Premium. Account deletion: 3-step dialog with typed "DELETE" — real deletion within 24 hours, not just "deactivated".
When should I see a doctor immediately instead?
Blood in stool, black stool, unexplained weight loss, fever, or severe persistent pain — these are red-flag symptoms that must not be dismissed as "normal IBS". DarmKompass flags them instantly in the entry sheet and directs you to medical review.
