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.

Benefits of Fasting Intermittent fasting has grown popular for its potential health benefits. Here are some of the main benefits: • Weight Loss: Intermittent fasting creates a calorie deficit, helping reduce calorie intake and promote weight loss. • Better Metabolism: Fasting can improve insulin sensitivity, help regulate blood sugar levels and boost metabolism. • Cellular Repair: During fasting, the body triggers autophagy, clearing out damaged components and promoting cellular renewal. • Heart Health: Intermittent fasting helps improve several cardiovascular risk markers, including lowering blood pressure, reducing triglycerides and improving cholesterol levels. • Brain Health: Studies suggest intermittent fasting may support brain health and cognitive function, and may even protect against neurodegenerative diseases like Alzheimer's. • Reduced Inflammation: Fasting can ease inflammatory responses in the body, and chronic inflammation is linked to arthritis, some cancers and various other conditions. Please note that intermittent fasting is not for everyone. If you have an underlying condition, are pregnant or taking medication, consult a healthcare professional before starting. A balanced diet and healthy lifestyle are what maximize the benefits of fasting.
