A beautifully crafted, completely private tracker for IBS. Record bowel movements on the Bristol Stool Scale, tag meals by FODMAP group and log symptoms, exercise, weight, blood pressure and supplements, plus your own personal daily journal.
Clean, Calm and Completely Private.
Log bowel movements on the Bristol Stool Scale (Types 1–7) with urgency, pain and notes — a clear, clinical record instead of a vague recollection.
Log meals with 23 food tags — the FODMAP groups plus common triggers and gut-friendly choices — and save favourite meals to log again in a tap.
Rate 49 symptoms across 5 categories on a five-point scale — bloating, pain, nausea, urgency and more.
Watch symptoms rise and fall on clear, beautiful charts — and spot the link between the foods you log and the days that follow.
Track your daily supplements, with reminders you can snooze or mark as taken straight from the notification — no need to even open the app.
Log weight in kg, lbs or st with visual trend charts. Monitor fluctuations alongside your gut health.
Log your temperature in °C or °F, timestamped, and watch the trend build week by week.
Log a reading — systolic, diastolic and pulse — and follow all three on one chart.
Track gentle activity and intensity from a built-in catalogue, or add your own exercises with Premium.
Keep every appointment in one place, with notes. Add reminders and a PDF report to take along with Premium.
Add your own symptoms and exercises alongside the built-in catalogue, so the app tracks your condition — not a generic one.
Choose which shortcuts appear on Home, drag them into your own order, colour them your way — and put your name at the top.
Set backups to run themselves, on a schedule you choose. Manual backup and restore stays free for everyone.
Turn months of logs into a clean, doctor-ready PDF — symptoms, bowel movements, food and supplements — ready to share at appointments.
All data lives on your device — no cloud, no accounts, no tracking — with a biometric app lock for good measure.
IBS is a pattern, not a single bad day — and the pattern only shows up if you record the detail. Lunaire IBS Tracker ships with 49 symptoms across 5 categories, ready to log on day one. With Premium, you can hide the ones that don't apply and add your own symptoms or exercises to track what really matters to you.
Bloating, distension and trapped wind are three different experiences that often get written down as one. Logging them separately is what makes a food diary worth keeping.
IBS-D, IBS-C and the alternating pattern all look different in a log. Frequency, urgency and incomplete evacuation are tracked as separate entries so the subtype shows up in the data rather than being guessed at.
Where the pain sits, and whether it arrives after eating, is often the most useful thing you can bring to an appointment. Pain is logged by location and by timing.
The gut-brain link runs both ways, and stress is logged as its own daily entry so you can see how it lines up with the weeks your gut was at its worst.
Gut symptoms that move with the menstrual cycle get their own category, because a flare that arrives every luteal phase isn't a food reaction. The whole category can be hidden if it doesn't apply to you.
The full FODMAP set is built in, alongside the usual suspects. Tag what you ate and it sits next to the symptoms you logged that day, so you can look back at both together.
Every symptom and exercise is rated on a simple five-point scale.
You can log the same symptom or exercise multiple times a day.
The above screenshots are just a small selection from the app.
All screenshots show example data, not real records.
Your symptom data is deeply personal. Lunaire IBS Tracker is designed from the ground up so your information never leaves your device. No sign-ups, no adverts, no analytics — just a beautiful app that respects you, your body and your data.
