## What is 天使と悪魔のファスティング?

Fasting Island makes intermittent fasting feel less lonely. With an angel cheering you on and a devil tempting you off track, every hour becomes a tiny story you star in.

KEY FEATURES

▷ Two companions, hundreds of lines
A gruff old angel and a nervous, stuttering devil react to every stretch of your fast. Pick the male or female version — each has its own voice, mood, and timing. They show up at the right moment with the right line, never repeating themselves for hours.

▷ See your body change in 6 stages
Watch yourself move through Digesting → Stable → Switching → Ketosis → Repair → Deep Repair. Each stage explains what's happening inside you, so you understand the why behind the timer.

▷ Three flexible plans
Pick a pace that fits you: 12:12 for first-timers, 14:10 once you're comfortable, or the classic 16:8. Swap anytime — your pace, your rules.

▷ Honest stats, no shame
Total fasts, longest streak, average — clear numbers. Tap any past session to see start/end times and goal status. No streaks-or-die guilt trips.

▷ Designed for real life
- Pause when you need to (long meeting, social meal, anything)
- Edit start times after the fact
- Notifications only when you hit your goal — no buzzing all day
- Works offline. Your data lives only on your device.

▷ Goal celebrations that don't feel cheesy
Hit your target and the screen fills with confetti while your two companions react in character. The angel's proud, the devil sulks (a little).

▷ One-time ad removal
Free with a tasteful banner ad. One small in-app purchase removes ads forever. No subscription, no upsells.

PRIVACY FIRST
Fasting Island stores everything on-device. No accounts, no cloud sync, no data shared with us. Your fasting history is yours.

NOT MEDICAL ADVICE
This app supports healthy habits but is not medical advice. Stop fasting if you feel unwell. Not recommended during pregnancy or with a history of eating disorders. If you have a chronic condition or take medication, consult a doctor first.
