Tend Fast

Tend Fast is a calm daily practice for intermittent fasting, with room for the eating window too. Choose a rhythm that fits your day. Track your fast, make time to eat, and keep an honest record of how each window felt. Optional reminders and private observations help you reflect without turning your routine into a streak to protect. Key features: Fasting Timer Start now or record when your fast began. Switch between elapsed and remaining time, adjust your goal, and finish whenever you choose. Widgets and Live Activities keep your timing close. Eating-Window Timer When a daily fast ends, your eating-window timer begins. See how long you have been eating and the time remaining, then start the next fast when you are ready. Routine and Reminders Plan the days and start times that work for you, with optional reminders and quiet hours. Skip or change a planned day when life changes. Tend Fast never starts or ends a fast automatically. History and Reflection Log past fasts, correct their times, record how they felt, and add a note. Review your history and weekly evidence, or export your records for a backup. Private Insights Explore observations only when there is enough comparable information. Inspect the supporting evidence and its limitations. With your permission, optional Apple Health and Oura connections can add context from available sleep and movement records. Connected services require their own accounts, permissions, and service availability. On-Device Apple Intelligence On supported iPhones running iOS 27 or later, with Apple Intelligence enabled and its model downloaded, Tend Fast can write a personal daily brief on the device. Other devices still show the checked observations and available next steps. Generated text can make mistakes. Privacy by Design Your fasting history, notes, check-ins, and personal observations stay on your device. No advertising or third-party analytics. No cloud AI processing of your notes or conversations. Manage connected sources and local data in Settings. Available in English and French, with light and dark appearances, three accent colors, Dynamic Type, and VoiceOver support. No Tend Fast account is required. Core tracking works without Apple Intelligence or connected health data. Tend Fast is intended for adults. It is a general wellness and personal tracking tool, not a medical device or a source of medical advice. Fasting is not appropriate for everyone. Consult a healthcare professional if you have questions about whether fasting is suitable for you, and stop if you feel unwell.
