About

Nüwa

Features
Read full description

Nü is your nutrition coach. She gets to know you: she plans your day, notices what's working and what isn't, and adjusts with you. No fad diet, and the food you already eat. NÜ PLANS YOUR DAY Tell her your goal, and Nü works out your calorie and protein targets from your body, your routine and what you want. Then she plans the day's meals between the time you wake up and the time you go to bed. Don't like one? Ask for another option, and she swaps it for something you actually want to eat. NÜ NOTICES She follows your week and points out what you wouldn't catch on your own, like protein that drops off at weekends. Every Monday, a review of the week: what worked, what to adjust, and new targets when they're warranted. TALK TO NÜ Ask what to eat now, what to order at a restaurant, or how to balance things after a barbecue. She suggests dishes at real restaurants near you, sized to what's left of your day and to your budget. And she remembers your plans: mention a party on Saturday, and afterwards she asks how it went. TELL HER WHAT YOU ATE • Photograph your plate and get an estimate straight away • Write it in your own words: "rice, beans and grilled chicken" • Or say it out loud, and Nü logs it for you Nü learns your dishes. The second time, they go in without a photo and without a wait. YOUR RESTRICTIONS ARE RESPECTED Lactose, gluten, peanuts, tree nuts, shellfish, fish, egg, soy, sesame: tell her what you can't eat, and no suggestion will include it.
