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.
