We don’t diagnose
We don’t say you’re flaring. We don’t advise changing medications. We don’t label lab results “normal” or “out of range”. It’s material from your logs for a conversation with your doctor.
Chronicos IBD
A system for Crohn’s & UC
Crohn’s and UC. History before your visit.
Chronicos IBD is a Crohn’s and ulcerative colitis diary. You log symptoms, meals, and meds, then make a PDF from your history before a gastroenterologist visit. The app does not diagnose.
Health data stays on your phone. iPhone and Android. This is not medical advice.
The problem
Lab PDFs. Meds in your head. Notes everywhere.
Chronicos IBD brings it together so before a visit you can see what the last weeks looked like. We are not a medical device.
How you log
Meals during the day. Symptoms in the evening.
With Crohn’s and UC, pain rarely hits the moment you finish eating.
- 01
Quick meal
Describe what was on the plate and tag traits (e.g. dairy, fatty). No calorie counting. You can also mark that you suspect that meal.
- 02
Day summary
One entry for the whole day: pain, energy, stool, blood, urgency. Usually in the evening, but you can log earlier.
- 03
Delayed patterns
The app shows which meal traits show up more often with higher pain — including a day or two later. That’s a diary observation to discuss with your doctor.
Signal
Home screen: today and what to do next
This is where your day starts: a week summary and one main button for what to log next. From here you also open Analysis, nearby toilets, or another meal.
PDF report
A pack for your gastroenterologist visit
Pick a period (e.g. a month), review a 15-second summary, and export a PDF: average pain and energy, harder days, comparison with the previous period, CRP or calprotectin values, medication list, food observations, and questions for your doctor. Conversation material, not a medical document.
Diary
Logged days: meals and how you felt, side by side
Browse days like a notebook: what was on the plate and how the day went (pain, energy, stool). At the top, a range summary shows whether things have been calmer or harder lately.
Analysis · History
Patterns and disease history, not a list of single days
In Overview: pain trend, metrics, and food observations. In History: calmer and harder periods, treatment starts, labs, and before/after windows around a medication start. Always from your logs, never as a diagnosis.
Meds
Medication list, “Taken”, and a calm dose status
Your meds with doses and times, plus “Taken” for today. Status is “X of Y marked”, not an alarming 0%. Your list and reminders, not dosing advice or a judgment of effectiveness.
Toilets
Find the nearest toilet when you really need one
A nearby map with access type (free, customers only, paid), distance, and one-tap navigation. Open from Signal, or use the shortcut when today’s check-in notes stronger urgency.
Data from OpenStreetMap. Chronicos does not guarantee that a specific toilet is open or available. Location is only used to find what’s nearby.
Calendar
Visits and planned labs
Under More you’ll find a calendar. You can save a doctor visit, a planned lab (e.g. calprotectin), or another date such as an infusion or a colonoscopy. The nearest visit shows on Signal. Three days earlier we’ll remind you about the PDF report, and the day before a lab about the appointment itself. If you want, you can add a single event to the calendar on your phone. The app does not sync your whole phone calendar.
More from the app
Report, treatment, labs
The PDF report packs a period into one file for your doctor. You also get treatment history and a list of lab results. View sample PDF report.

Clear boundaries and privacy
Data: on-device and optionally EU cloud
