Ocras

You donβt 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 thatβs pretty much it. Ocras works out your current fasting state from your schedule and shows it at a glance. Thereβs no need to start or stop a fast manually. No notifications telling you when to eat. No account to create. You shouldnβt have to open the app several times a day just to keep a fasting timer accurate. If itβs 3pm on a Tuesday, Ocras should simply be able to tell you at a glance whether youβre 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. * Thereβs no social feed or sharing. * Thereβs no account to maintain. * Thereβs 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: Iβm 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!

Verdict
The clearest difference is in-app purchases: Flow at none against Ocras's 1. Ocras's advantage is update cadence (every 4 days vs every 3 weeks) and device support (3 vs 1). On price, ads and iOS requirement there is nothing between them.
