SheFast Premium is an auto-renewing paid subscription required for full access to SheFast’s features, including cycle-aware fasting plans, fast tracking and history, reminders, guided course content, and progress insights. Most fasting apps treat every day the same. Your body does not. SheFast is fasting designed around your cycle. It keeps track of your current phase, menstrual, follicular, ovulatory, or luteal, and suggests fasting windows that fit it, so you can stay consistent without fighting your own energy, hunger, or sleep. No pushing through. No starting over every Monday. Just a rhythm that bends when your body needs it to. FASTING THAT FOLLOWS YOUR CYCLE See your phase at a glance and get windows suggested for it. Gentler options when your body asks for ease, more room to stretch when your energy is up. A TIMER THAT KEEPS IT SIMPLE Start, adjust, or end a fast in seconds. Clear progress, calm design, no clutter. REST DAYS THAT PROTECT YOUR MOMENTUM Life happens. Period days happen. Plan rest days ahead and keep your streak intact, because taking care of yourself should never feel like falling behind. A GUIDED DAILY JOURNEY A short, friendly course that builds day by day. Learn how fasting and your cycle interact, at a pace that starts where you are. YOUR HISTORY, BEAUTIFULLY KEPT A calendar of every fast, rest day, and phase, so you can look back and watch your rhythm take shape. SMALL WINS, COUNTED Streaks and achievements that reward consistency, not perfection. WATER AND PROTEIN, ONE TAP AWAY Quick adds for water and protein, plus manual entries when you want more control. Weight tracking is there if you choose it, never in your face. REMINDERS THAT RESPECT YOU Gentle notifications for fast starts, fast ends, and hydration. You choose what you hear and when. PRIVATE AND SIMPLE Sign in with Apple or email. Your data syncs to your account and stays yours. MEMBERSHIP SheFast is a subscription with weekly, monthly, and yearly plans. Prices are shown in the app. Payment is charged to your Apple ID account at confirmation of purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel anytime in your App Store account settings. A NOTE FROM US SheFast is made by a small independent team. We built the app we wished existed: warm, unhurried, and shaped around real bodies and real weeks. A GENTLE NOTE ON HEALTH SheFast is for general wellness and is not medical advice. It does not diagnose, treat, or prevent any condition, and everyone's body is different. If you are pregnant, breastfeeding, trying to conceive, have a history of disordered eating, or have any health condition, please talk with your doctor before fasting. Your body already has a rhythm. SheFast helps you work with it. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
