Vasten does one job well: it keeps an accurate record of your fast. Start in one tap, see elapsed time and your goal on the main screen, and keep the timer visible through a Home Screen widget, Lock Screen Live Activity, and Dynamic Island. Reaching the goal never ends the fast automaticallyβ€”you decide when it ends. Your history remains useful and under your control. Correct start and end times, review simple totals, import Vasten JSON or Zero history, export everything as JSON or CSV, or delete any record. Features: β€’ One-tap start with an adjustable start time β€’ Custom fasting goals from 1 to 168 hours β€’ Clear widget goal progress and goal end times β€’ Lock Screen and Dynamic Island Live Activity β€’ Small and medium Home Screen widgets β€’ Separate timer and 12-week fasting-activity widgets β€’ Custom accent colors shared across the app and widgets β€’ Editable history and summary statistics β€’ Configurable local goal-time notification β€’ Vasten JSON and Zero fasting-history import β€’ Private device storage with private iCloud synchronization β€’ JSON and CSV export β€’ English and Dutch β€’ No account, ads, analytics, or subscription Stage labels are general educational time ranges.

See how long you've been fasting right on your Lock Screen β€” without opening the app. Fasting Timer is an intermittent fasting clock that shows your day as a 24-hour dial. Instead of a progress bar, your fast is drawn as an arc on a real clock face β€” "from 9:30 last night until 1:30 this afternoon" β€” so you see when you can eat, not just how long you've held on. ● Lock Screen widgets, Live Activity and Dynamic Island β€” always accurate, even with the app closed ● No 23-hour cap β€” the arc keeps growing past your goal ● Zero ads, no account, no server β€” fully local, works offline ● Your history stays β€” a 30-day dial calendar plus automatic iCloud backup ● Reminders for your first meal and your next fast Free forever - Timer with 16:8, 18:6, 20:4 and OMAD presets - Lock Screen widgets (circular, rectangular, inline) and Live Activity - Overtime counting, 30-day history, iCloud backup Premium (subscription) - Custom fast length (1–72 hours) and extended 36/72-hour fasts - Full history beyond 30 days - CSV export About subscriptions: Premium is a monthly or yearly subscription. The yearly plan starts with a 7-day free trial. Subscriptions renew automatically unless canceled at least 24 hours before the end of the period, and payment is charged to your Apple ID account. Manage or cancel in your App Store account settings. This app provides general reference information and is not medical advice. Consult a professional before fasting if you have a health condition.
