Nomu's answer
The fasting timer that makes the invisible part visible
Most fasting apps are a number counting up. Nomu is a caterpillar that spins a cocoon as your body enters fat burning and emerges as a butterfly when you finish. It sounds silly. It is the reason people stop quitting at hour 13.
Nomu's answer
I got tired of fasting apps that are 90% upsell and require an account to run a timer. So I built Nomu (Flutter, iOS + Android + watchOS).
The core idea: fasting phases (fat burning -> ketosis -> autophagy) are invisible, so people quit mid-fast. Nomu maps them onto a mascot that visibly transforms - caterpillar to cocoon to butterfly - and a streak system that evolves its wings over 180 days. A tamagotchi-style loop beats charts for habit retention.
Technical bits: - Local-first: SQLite on device, no accounts, no backend for user data. Export is CSV/JSON. - Flutter + native watchOS app, Home/Lock Screen widgets, Control Center controls via App Intents - Apple Health sync, live phase notifications, auto eating-window countdown - 14 locales, paired haptics + sound design for every interaction
Business model experiment: free-for-life for anyone who installs by September 11 (enforced by a date constant in the app, no server), then a hard paywall for new users only. Early users are grandfathered forever - they're the word-of-mouth engine.
Nomu is built by Tappect, the indie studio behind Nutrify, the AI calorie tracker used to log meals with a photo - see https://www.nutrifytracker.com. Both apps share the same philosophy: private by design, delightful to use daily. Nutrify ships the same local-first pattern with an on-device-first pipeline for food logging.
