Nerva vs Macro & Calorie Calculator

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.

The calorie calculator that shows its work. Most calorie and macro calculator apps give you a number. This one shows you exactly how it got there — every formula, every multiplier, every step. No black box. No account required. CALORIE CALCULATOR Enter your age, sex, weight, height, activity level, and goal. Your daily calorie target is calculated using the Mifflin-St Jeor equation — the most accurate BMR formula for the general population — then adjusted for activity (TDEE) and your goal (fat loss, maintenance, or muscle gain). Safety floors are applied automatically. MACRO CALCULATOR Get a recommended protein, carb, and fat split based on your goal and BMI — or drag the sliders to set a fully custom macro split. Grams and kcal update instantly. Your macro percentages always total 100%. BMI CALCULATOR Your BMI isn't just a number here — it actively adjusts your calorie deficit tier and macro recommendations. Larger deficits are applied at higher BMI ranges where they're appropriate and safe. FLUID NEEDS CALCULATOR Your daily water target is calculated from your effective body weight, activity level, BMI, and age — not a generic "8 glasses a day." See exactly why your number is what it is. SHOW THE MATH Every screen has a "Show the math" toggle. Tap it to see the full equation with your actual numbers plugged in. Understand what you're being told. Share your results with one tap. WHAT MAKES THIS DIFFERENT Mifflin-St Jeor equation, not the outdated Harris-Benedict Fluid needs adjusted for BMI and age, not a flat rate Macros that account for your body composition No food logging, no ads, no account Built for people who want to understand the numbers, not just follow them WHO IT'S FOR Whether you're tracking macros for fat loss, calculating TDEE before a bulk, checking your BMR, or just figuring out how much water to drink — this is the calculator that treats you like an adult. Simple. Transparent. Evidence-based. MACRO CALCULATOR PRO (OPTIONAL) Everything above is free, including up to 4 saved profiles. Macro Calculator Pro adds unlimited saved profiles and supports a small, independent, ad-free app. It is a monthly or yearly auto-renewable subscription: payment is charged to your Apple ID at purchase, and it renews automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel anytime in your Apple ID account settings.
