About

Vasten

Features
Read full description

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 automatically—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: • One-tap start with an adjustable start time • Custom fasting goals from 1 to 168 hours • Clear widget goal progress and goal end times • Lock Screen and Dynamic Island Live Activity • Small and medium Home Screen widgets • Separate timer and 12-week fasting-activity widgets • Custom accent colors shared across the app and widgets • Editable history and summary statistics • Configurable local goal-time notification • Vasten JSON and Zero fasting-history import • Private device storage with private iCloud synchronization • JSON and CSV export • English and Dutch • No account, ads, analytics, or subscription Stage labels are general educational time ranges. They are not measurements of your body or medical advice.
