ArcFast is a simple fasting tracker built around a free, no-ads intermittent fasting timer. Start a fast in one tap, follow your fasting window, use reminders and widgets, and review your history without clutter. KNOW YOUR BODY ArcFast displays your current metabolic phase in real-time as you fast: Sugar Burning transitions into Fat Burning, then Ketosis and Deep Ketosis. Stay informed about what's happening inside your body during every fasting window. SEE YOUR PROGRESS Fasting streaks, weekly bar charts, and detailed session history help you spot patterns and celebrate consistency. Review any missed fasts and learn from your patterns over time. BEAUTIFUL THEMES Four carefully crafted themes — Cosmos, Midnight, Cloud, and Linen — let you personalize ArcFast to match your style. Your fasting experience should feel as good as it looks. FLEXIBLE FASTING PLANS Choose from popular presets including 16:8, 18:6, 20:4, 22:2, and OMAD — or create a custom fasting schedule that fits your lifestyle. STAY ON TRACK Daily reminders to start and end your fasts, milestone notifications, and streak nudges keep you accountable without the noise. WIDGETS Add ArcFast widgets to your Home Screen for quick at-a-glance fasting status without opening the app. FOOD SCAN Add quick calorie estimates to your fasting routine. Take a photo of your meal and ArcFast gives you a clear estimate of calories and food items, so you can understand what you eat between fasting windows. Estimates are for guidance only and are not medical or nutritional advice. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
Orbo

Orbo is an intermittent fasting timer that does one thing properly. Start a fast in one tap. Watch the ring fill. See exactly which stage your body is in and how long until the next one. End it when you're done. The timer is the app. When you want to log a meal, the AI scanner is one tap away — and when you don't, it stays out of the way. No account, no quiz, no ambush. — EVERY FAST, FULL CIRCLE — Pick a schedule — 16:8, 18:6, 20:4, OMAD, a 13-hour circadian fast, or anything you like from 1 to 168 hours. Orbo tracks it and stays out of your way. — SEE WHAT'S ACTUALLY HAPPENING — Five stages, marked on the ring as you reach them: Anabolic · Catabolic · Fat Burning · Ketosis · Deep Ketosis We tell you which stage you're in and what it means. We don't invent numbers we can't stand behind. — FORGOT TO START IT? FIX IT. — Edit your start time. Edit your finish time. Add a fast you never logged at all. Your streak heals when you do. Most apps make this impossible — it's one tap here. — A REST DAY THAT DOESN'T BREAK YOUR STREAK — Every week you get a rest day. Take it, and your plan extends instead of your streak resetting. It's free. Other apps charge for this, which is backwards. — YOUR DATA IS YOURS — Orbo works completely offline. No account required — not now, not later. Export everything to CSV or JSON whenever you want, on the free plan. Nothing about your fasting is held hostage. — ARABIC, PROPERLY — Full Arabic with real right-to-left layout, correct plurals, and Saudi phrasing. Not a machine translation with the text flipped. — FREE FOREVER — The timer, every schedule, all five stages, streaks, history, and export are free and always will be. Orbo Premium adds personalised stage estimates, correlations and custom saved presets. Premium is 9 SAR/month, 29 SAR/6 months or 49 SAR/year, with a 7-day free trial. Cancel any time in two taps — there's a button inside the app that shows you how. — — —— — —— — —— — — Orbo is not a medical device and does not give medical advice. Talk to a doctor before starting any fasting programme, especially if you are pregnant, breastfeeding, diabetic, taking medication, or have a history of eating disorders.
