AI Coach Settings
AI Coaching
ON
Your check-in scores adapt tomorrow's fasting window. Switch to Manual or Timer mode above to turn this off.
Skip AI Today
ACTIVE
Tap to opt out of today's AI adaptation. Your check-in still works — we just won't adjust your protocol based on today's scores. Resets automatically tomorrow.
🧠 Manual Mode — you're in full control.
Your fasting protocol stays exactly as you set it. No AI decisions, no automatic adjustments, no coaching emails. Your fast history still shows up on the dashboard. Switch back to AI Coach anytime.
⏱ Timer Mode active.
Just the timer. No check-ins, no AI coaching, no emails, no weekly recaps. Your fast history is still tracked. Use the Timer tab on the dashboard to start and stop fasts. Switch back anytime.
Cycle-Synced Fasting NEW
Cycle-Aware AI
OFF
AI automatically adjusts your fasting window based on your cycle phase — shorter during menstrual/luteal, longer during follicular/ovulatory. Based on Dr. Mindy Pelz's hormonal fasting research.
Perimenopause Mode
OFF
For users 45+ whose hormonal patterns are less predictable. Uses wider safety margins and capped adjustments. Never extends past 18:6. Turn on if your cycles have become irregular.
No dark patterns here. These toggles are first-class features — not buried, not guilt-tripped. If AI coaching isn't for you, Timer-Only is a legitimate way to use Circafast forever.
