Meridian is the fasting app for people who are tired of fasting apps. No 15-screen onboarding quiz. No AI coach upselling you a meal plan. No gamification badges. No paywall on the timer. Just a clean, powerful tool that respects your intelligence and your time. START IN SECONDS One tap to start. One tap to stop. Meridian tracks your fasting window, shows what's happening in your body at each metabolic phase, and stays out of your way. Every schedule built in — 14:10, 16:8, 18:6, 20:4, OMAD, or set your own custom window. REAL SCIENCE, NOT SLOGANS Each body phase is grounded in peer-reviewed metabolic research.

About

Ocras

Features
Read full description

You don’t need another fasting app begging for your attention and tracking your data. Ocras is a simple fasting app built around one question: am I eating right now, or fasting? Set your eating window once, add a widget to your Home Screen, Lock Screen, or Apple Watch, and that’s pretty much it. Ocras works out your current fasting state from your schedule and shows it at a glance. There’s no need to start or stop a fast manually. No notifications telling you when to eat. No account to create. You shouldn’t have to open the app several times a day just to keep a fasting timer accurate. If it’s 3pm on a Tuesday, Ocras should simply be able to tell you at a glance whether you’re inside your eating window, without you unlocking your phone. What Ocras does * Set a different eating window for each day of the week, or use the same schedule every day * Choose from common schedules like 16:8, 18:6, 20:4 and OMAD, or make your own * Add widgets to your Home Screen and Lock Screen * Add widgets and complications to your Apple Watch * Choose from different widget styles, including the original designs, retro-inspired widgets and vaporwave themes * Check your fasting status without opening the app * Works completely offline - no cloud needed What Ocras deliberately does not do: * There are no notifications. * There’s no social feed or sharing. * There’s no account to maintain. * There’s no internet connection required for the core app (only if you want to unlock the additional widgets). * Your schedule and fasting data stay on your device - Ocras does not track anything about you. The aim is to keep Ocras useful without turning fasting into another thing you need to manage. Still growing: I’m continuing to add new widget designs, including more customisation options, and support for longer multi-day fasts is planned too. For now, Ocras is intentionally small: set your schedule, put a widget somewhere useful, and get on with your day. Set once. Glance when you need it. Happy fasting!
