## What is Fern?

Fern is a fasting timer built around one idea: the app should feel like a companion helping you succeed, not a rule enforcer tracking whether you comply.

FREE, NO ACCOUNT REQUIRED
• Every fasting protocol — 16:8, 18:6, 20:4, OMAD, 5:2, and more — free, no paywall
• A calm, stage-aware timer with a Live Activity and Dynamic Island support
• Streaks that forgive a missed day instead of resetting to zero
• Milestone badges from 12 hours to 48 hours
• Full history with edit/delete, and a real daily-hours chart
• Reminders for both sides of the window — when your fast is ending, and when your eating window is about to close
• A Home Screen widget showing your streak and live countdown

FERN+
• Circadian Smart Schedule — automatically lines up your next fast around your actual sleep pattern, and lets you fine-tune it on an interactive 24-hour dial
• Fasting Insights — real correlations between your fasting consistency and your sleep, not just a trend line
• A widget gallery, including a 14-day adherence widget and one-tap start/end from your Home Screen
• Personalized nudge timing, tuned to when you actually tend to break a fast
• Deeper analytics against your weight and sleep trends (with Apple Health connected)
• Fully custom protocol configuration

Fern never asks for an account. Your fasting history stays on your device — there's no backend, no analytics, no tracking.

Fern+ is an auto-renewing subscription. Payment is charged to your Apple ID at confirmation of purchase. Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the end of the current period. Manage or cancel anytime in your Apple ID account settings.
