IBS & Gut Health Tracker

IBS symptom, food & bowel tracker. Private. Offline. Your device only.

Living with IBS means knowing which bathroom is closest at every restaurant, cancelling plans because of a flare, and explaining to yet another doctor that yes, it really is that disruptive. Lunaire IBS Tracker is a private, offline gut health and food diary built for patients who are tired of cloud-based apps, ads and accounts that harvest their health data.

Every bowel movement, food trigger, bloating episode and pain flare you log stays on your phone. Always. We don't have a server. We can't read your data. We never will.

WHAT YOU CAN TRACK

• Bowel movements with the Bristol Stool Scale (types 1–7)
• Abdominal pain and cramping severity (1–10 scale)
• Bloating and gas
• Urgency, incomplete evacuation and other IBS symptoms
• Food diary — find your personal trigger foods
• Low FODMAP elimination and reintroduction
• Stress, mood and anxiety levels
• Sleep quality
• Exercise and gentle activity
• Supplements and medications (including probiotics)
• Weight and body changes

PRIVACY-FIRST BY DESIGN

Most IBS apps need an account, run ads, or sync your gut health data to their servers. Ours does none of that.

✓ No accounts. No sign-up. Open the app and start logging.
✓ No cloud. Your data lives in a local database only you control.
✓ No ads. Ever.
✓ No tracking. No analytics. No third-party SDKs.
✓ Full offline — works with no internet, anywhere.

FIND YOUR TRIGGERS

The single most useful thing an IBS tracker can do is show you which foods, stress patterns and habits are driving your flares. Lunaire IBS Tracker correlates your food diary against your symptom log automatically — no spreadsheets, no guesswork. Spot your personal FODMAP triggers, caffeine sensitivity, dairy reactions or stress-driven flares from your actual data.

PDF REPORTS FOR YOUR GASTROENTEROLOGIST

IBS diagnosis usually relies on symptom history. Accurate tracking is one of the most useful things you can bring to a consultation. Generate a clean, professional PDF report of your bowel patterns, trigger foods, pain frequency and flare severity — ready to email, print or share with your GP, gastroenterologist or IBS specialist.

BUILT FOR IBS PATIENTS, NOT MARKETERS

This isn't a generic food diary. Every category, every symptom list, every chart was designed around what IBS patients actually track: Bristol Stool types, abdominal pain cycles, FODMAP triggers, bloating severity and the stress-gut axis.

If you live with IBS-C, IBS-D, IBS-M, SIBO, functional bowel disorders or chronic digestive symptoms, this tracker is built for you.
