IBS symptom, food & bowel tracker. Private and offline.
Read full description
Living with IBS means knowing which bathroom is closest at every restaurant, cancelling plans because of a flare, and explaining to another doctor that yes, it really is that disruptive. Lunaire IBS Tracker is a private, offline gut health and food diary.
WHAT YOU CAN TRACK
• Bowel movements with the Bristol Stool Scale
• Abdominal pain and cramping severity
• Bloating and gas
• Urgency, incomplete evacuation and more
• 49 built-in symptoms in total
• Food diary — see which foods line up with how you feel
• Stress, mood and anxiety levels
• Sleep disruption
• Exercise, by type and intensity
• Supplements
• Weight in kg, lbs or st
• Blood pressure, pulse and temperature
• Appointments, with notes (reminders with Premium)
• Daily notes on any category
Every symptom and exercise is rated on a simple five-point scale — you can log the same symptom or exercise multiple times a day. Many people live with more than one condition, so with Premium you can add symptoms of your own and hide the ones you don't use — the lists end up matching you.

PDF REPORTS (PREMIUM)
IBS diagnosis usually relies on symptom history, so accurate tracking is one of the most useful things you can bring to a consultation. Generate a clean PDF of your bowel patterns, the foods that line up with your symptoms, pain frequency and flare days — ready to email, print or share.
SPOT YOUR PATTERNS
Lunaire IBS Tracker keeps your food diary and symptom log side by side, so you can read the pattern from your own data — no spreadsheets, no guesswork. Every category and chart is built around what IBS patients actually track. For IBS-C, IBS-D, IBS-M, SIBO and chronic digestive symptoms.
