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.

Verdict
The clearest difference is in-app purchases: Faex Health at none against Nerva's 4. Faex Health also leads on review sentiment (100% vs 73%) and rating (5.0 vs 4.7). Nerva's advantage is update cadence (weekly vs every 8 months) and ratings volume (15K vs 20). On price, ads, device support and iOS requirement there is nothing between them.
