Most fasting apps nag. Fasting Coach listens.
It's a calm intermittent fasting tracker with a personal AI coach that lives on your iPhone. The coach reads how your fast is going and what has helped you before, and checks what you've asked it not to do. Then it decides whether a message would really help. Often the kindest thing it does is stay quiet, so when it does speak, it matters.
PICK A PLAN, START IN SECONDS
• Named plans: 12:12, 14:10, 16:8, 18:6, 20:4 and OMAD, or set your own length
• Or run an open fast and celebrate milestones at 12, 16, 20 and 24 hours
• A clear, glanceable ring shows where you are and when you can eat
• A Live Activity keeps your fast on the Lock Screen and in the Dynamic Island
• Ask Siri: "Check my fast in Fasting Coach" or "When can I eat in Fasting Coach"
A COACH THAT GETS TO KNOW YOU
• Chat by text or voice when hunger hits, and get a short, kind, useful reply
• It remembers what works for you and what doesn't, like "no percentages, please" or "don't message me before 9"
• It learns roughly when you sleep and times its check-ins around your day
• After a fast that felt rough, it softens its tone and never pushes for more
• See its reasoning anytime in "How your coach thinks": what it has learned, what it did and why, and the rules it can't break
SEE YOUR RHYTHM BUILD
• Every fast in one place, grouped by month, with how it went and how it felt
• Tap any fast for its details
• Weekly consistency, an eight-week trend against your goal, and month-by-month averages
• Streaks and personal bests, without the pressure
PRIVATE BY DESIGN
• No account, no sign-up, no ads, no tracking
• Your fasts, your chats, your Health data and the AI itself all stay on your iPhone
• Works fully offline
• Optional Apple Health: steps, sleep, activity and workouts help the coach time its support. Read-only, never shared
• You set the limits: quiet hours and how often it can message you. The coach can choose to say less. It can never say more.
SAFETY COMES FIRST
Fasting Coach never encourages you to go past the goal you chose. If you say you feel faint or unwell, it stops coaching and tells you to eat. It offers lifestyle support, not medical advice. Please talk to a doctor before fasting if you are pregnant or breastfeeding, have diabetes, have a history of eating disorders, take prescription medication, or are under 18.
The AI coach needs an iPhone that supports Apple Intelligence. Fasting plans, tracking, history, trends, the Live Activity and Siri work on any supported iPhone.
Built for iPhone Duo. Fasting Coach doesn't just stretch to fill the inner display. It uses the fold. Stand the phone half open on your desk and the layout splits at the hinge: your fasting ring and the time of day on the upper half, your coach on the lower half with a mic and a single Start Fast or End Fast button. No keyboard, no scrolling. You talk, the coach answers out loud. Turn it sideways and open it like a book, and Home takes the left page while Insights, History and Plans sit on the right, so you can glance at your progress and your plan in one look. Fold it shut and the four familiar tabs are back on the outer screen, exactly where you left them. And one small touch: the misty lake behind your ring goes from night to morning as you open the phone, following the hinge angle itself.
