## What is Plainfast?

Plainfast is the honest fasting timer. Start a 16:8, 18:6, 20:4 or OMAD fast in one tap and watch a calm dial count the hours. No sign-up quiz, no account, no ads.

Open the app and the timer is the first thing you see. You do not answer fifty questions about your body first, and you do not lose your past fasts after a week. Every fast you log stays in your history, free, for as long as you use Plainfast.

WHAT IT COVERS
• Intermittent fasting with 16:8, 18:6, 20:4 and OMAD presets, or a custom target that suits your day
• Longer fasts: the clock keeps running past your goal, so 24, 36 and 72 hour fasts are timed hour by hour
• Water fasts and extended fasts logged the same way as your daily window
• A 10-phase timeline of what typically happens as a fast goes on: glycogen use, the shift toward fat burning, ketosis, and the hours that research often links to autophagy

KEY FEATURES
• A plain dial that shows time elapsed, time left and your current phase at a glance
• Live Activity and Dynamic Island, so your fast keeps time on the lock screen
• Home screen widgets
• Reminders for the start and end of each fast
• Full history, streaks and stats, all free
• Weight log, plus mood and glucose logs after each fast
• Export your fasting history as a CSV file
• Dark mode that is designed, not just inverted

WHO IT IS FOR
• Beginners trying 16:8 who want a timer, not a program
• OMAD and 20:4 regulars who log every day
• Anyone who does an occasional 36 or 72 hour fast
• Women and men who would rather track quietly than take a quiz first

PRICING
Free: the timer, all presets, the phase timeline, full history, streaks, stats, logs, widgets and reminders.
Premium (monthly, yearly or a one-time lifetime unlock) adds unlimited custom presets, adding past fasts, and mood and glucose correlation charts.

Plainfast is a timer and a log, not medical advice. If you are pregnant, diabetic, take medication or plan a fast longer than 24 hours, talk to your doctor first.

Payment will be 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 in your App Store account settings.
