YOUR NEXT WEEK Compare saved activity from two complete weeks, then explore a seven-day schedule around your days. The comparison and editable preview are free. Saving and using the schedule requires Premium, a safety review and your confirmation. A schedule never starts a fast automatically. SAVE YOUR SETUP Save, preview and share routine configurations for free. Shared links include only the routine name, schedule and appearance, not health records, profile or purchase data. Recipients review a preview before choosing whether to apply it. Applying a weekly schedule requires Premium and safety review. FREE TO START The timer, daily presets, free one-week schedule starters, static weekly templates, basic weekly recap, Time Capsule, Year in Review, hydration, optional weight, basic history and safety settings are free.

FASTA PREMIUM Premium adds editable weekly fasting schedules, the private on-device coach, 30-day reports and CSV exports, premium themes and premium timer styles. Choosing a coach tone does not unlock Premium coach features. Local prices and subscription terms appear before purchase. Any trial depends on the selected store offer and your eligibility. APPLE WATCH, WIDGETS, AND HEALTH Stay oriented from your wrist, widgets, Lock Screen or Live Activity. Apple Health is optional. With permission, Fasta can read weight, water, sleep, HRV, resting heart rate, steps, active energy and blood glucose as logged context, and write water and weight entries you log in the app. Logged context is not a health or fasting-safety assessment. PRIVATE BY DESIGN Fasta uses local device storage. Your core fasting data stays on your device unless you choose to export or share it. You control optional health permissions. IMPORTANT Fasta is for general wellness and fasting habit support, not medical advice. If you are pregnant, under 18, have a medical condition, have a history of disordered eating, or are unsure whether fasting is appropriate for you, speak with a qualified health professional first.
