Address the miscommunication between your gut and brain. Designed for people living with IBS, functional dyspepsia (FD), GERD, bloating symptoms, and other gut–brain disorders - as well as those seeking additional support alongside IBD care - Nerva is a personalized gut–brain program that supports symptom management through daily sessions, practical tools, and structured guidance. Target the root cause Many people spend years cutting out foods in an effort to calm their gut - a difficult path that can miss what’s really driving symptoms. In disorders of gut–brain interaction (DGBIs), the root cause is gut–brain hypersensitivity. After a trigger like illness, antibiotics, or prolonged stress, the nerves in the gut can become over-reactive. Even once the gut tissue heals, the nervous system may keep the alarm turned up. Normal digestion, gas, or movement are then misread as danger - leading to pain, bloating, reflux, urgency, constipation, or diarrhea. Diets and medications can reduce symptoms temporarily, but they don’t retrain this signaling system. That’s why symptoms often return or shift over time. Lasting relief means calming the nervous system and restoring healthy gut–brain communication - where the symptoms actually start. How Nerva helps Nerva is a structured gut–brain program that helps you practice brain-gut techniques shown to support a calmer response to gut sensations. Over the program you'll learn to: - Respond differently to uncomfortable gut signals - Practice calming the gut–brain stress response - Build daily habits that support digestive comfort Tailored to you No two guts are the same. Nerva adapts your program to your symptoms, triggers, and progress - using AI to adjust the coaching and guidance as you go. The sessions, the tools you receive, and the coaching you follow are all shaped around your experience. Evidence-based Unlike most apps, Nerva is built on clinical research. In a randomized controlled trial at Monash University, Nerva helped 81% of people significantly manage their gastrointestinal symptoms. Since then, more than 300,000 people have used Nerva, and over 11,000 healthcare providers recommend it. Features of Nerva - Daily 15-minute sessions designed to retrain gut-brain miscommunication - Flare-up tools for pain, bloating, constipation, reflux and diarrhea - Long-term maintenance plan to keep symptoms under control after the program - AI personalization to tailor the program to your selected triggers and progress Who is the team behind Nerva? Nerva was built by Dr. Simone Peters, GI psychophysiologist, together with clinicians, dietitians, and researchers. Many of us live with gut conditions ourselves.

Constipation is miserable, and it's confusing. You drink more water, add fiber, try the supplement a friend swears by… and a week later you still can't tell whether anything actually changed. Most health apps are no help here. They weren't built for this. Poopaya was built for this. Poopaya is a bowel tracker built specifically for constipation, designed by someone who spent 13 years dealing with it. It's for people managing chronic constipation, IBS-C, GLP-1-related constipation, dealing with a new diet or a gut that just changed one day. Poopaya helps you stop guessing about what's going on in there. TRACK IN SECONDS Log a movement in under 10 seconds: shape on the Bristol Stool Scale, urgency, effort, and how complete it felt. Add symptoms, diet, medications, and lifestyle factors when you want to, and skip them when you don't. You can even log the days when nothing happens at all. If you're constipated, those days matter most. NEW: THE TACTICS TOOLKIT Over forty things that can help with constipation, free for everyone. Each one covers what it is, how to do it right, what the evidence says, when to expect results, and when to see a doctor instead. Answer six quick questions and the Toolkit is tailored to the kind of constipation you have. With Poopaya Gold, turn a tactic into an experiment. Try it for a set number of days, log as usual, and check in once a day. At the end, Poopaya compares your movements with the weeks before and gives you a straight answer: what changed, by how much, and in which direction. CONSTIPATED BY A MEDICATION? Plenty of medications back you up, and with GLP-1 weight-loss and diabetes medications, constipation tends to hang around longer than the other side effects. Poopaya tracks your meds right alongside your movements, so you can see how your body is responding over time and what helps you stay regular while you're on them. DISCOVER WHAT WORKS Poopaya is grounded in the Bristol Stool Scale and gastroenterological best practices, so it captures the details that matter for your gut instead of step counts and calories. The more you track, the clearer the picture gets: which foods help, which habits matter, and whether that new approach is doing anything at all. SHARE IT WITH YOUR DOCTOR Export your complete history (movements, symptoms, medications, diet) as a CSV, free. Walk into your next appointment with data instead of vague recollections. POOPAYA GOLD Upgrade when you're ready: • Guided experiments: test one tactic at a time and find out whether it helped • Your top matches: the three tactics that best fit your specific kind of constipation, and what you have logged • Intelligent Insights: personalized indicators that learn your baseline and show what affects you most • Trends & charts: watch your patterns shift over weeks and months • Face ID & app lock: extra privacy for your most personal data • Multiple reminders: your first daily reminder is free, Gold unlocks more, on your schedule, not ours YOUR DATA STAYS ON YOUR DEVICE Poopaya stores everything locally on your iPhone. No account required. Your gut health data is yours alone. Built by someone who gets it, for people who are done guessing and ready to make real progress.
