NightFast helps you stop late-night snacking, without willpower speeches. When your night window starts, NightFast steps in with a gentle prompt, right when the fridge starts calling. Each morning, one tap tells it how the night went. Good nights build a streak. Snack nights get zero judgment. HOW IT WORKS • Take a 60-second quiz about your nights. NightFast builds your night window around it. • Gentle night prompts during your window: supportive, direct, gentle, or funny, your choice. • Craving? Start the 10-minute timer and wait it out with a breathing circle and small ideas. Most cravings fade. • Morning check-in: "How was last night?" One tap, and your good-night streak grows. See every night on the Nights calendar. • Spot your pattern: after a night snack, tap what was behind it (bored, stressed, tired, hungry, habit). • An on-device AI learns when your cravings hit. See exactly what it reads and how it decides, 100% on your iPhone. • Every Sunday, a short recap of your week of nights. LOG WHAT YOU EAT • Search foods or scan a barcode • Quick Log and Manual Entry for the 2 AM moments • Calories and macros at a glance • Pin your usual snacks for one-tap logging • Light night bites: easy, sleep-friendly recipe ideas for when you're actually hungry • Home Screen and Lock Screen widgets (including your good-night streak) and Live Activities during night hours • "Hey Siri, I'm craving a snack" and a Control Center craving button • Choose your Home: the live AI view or a card dashboard you arrange FREE • 20 food logs a day • Night prompts, craving timer, morning check-in, streaks, and on-device AI NIGHTFAST PRO • Unlimited food logging • Custom meal schedules for any night or shift pattern • Detailed insights and trends • Apple Health sync • Grocery lists • Family Sharing (up to 5 people) Works for night owls, new parents, and night-shift workers.
