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!

Your Apple Watch knows more about you than you think. Vitae turns all that data — VO₂ max, resting heart rate, HRV, sleep, recovery, daily movement — into one number you'll actually understand: your health age. Some weeks you'll be younger than your years. Some weeks you won't. Either way, you'll know exactly why. What you get every week: • Your health age, calculated from 9 key metrics • What's helping you, ranked • What's holding you back, ranked • Trends so you can see real progress Built on real research. Every comparison comes from peer-reviewed studies and official health guidelines (FRIEND registry, WHO, AASM, and more). Tap any metric to see exactly where the numbers come from. Works with your Apple Watch. Wear it consistently, track your sleep, get a workout in, and Vitae handles the rest. Vitae is not a medical device and does not provide medical or diagnostic advice. It's a tool for visualising and understanding your own health data. Always consult a healthcare professional for medical concerns.
