SleepKit measures your night and tells you what it actually knows. TRACK WITH YOUR IPHONE — OR YOUR WATCH Put your iPhone on the nightstand and SleepKit records the night: how long you slept, how restless you were, when you drifted off. Wear an Apple Watch and it uses the watch's measured sleep stages instead of an estimate — automatically, with nothing to set up. HONEST ABOUT WHAT IT MEASURES Every night carries a badge: measured on your watch, or estimated by your phone. Tap it and SleepKit explains what an iPhone on a nightstand can and cannot see — someone else in the bed, a loud room, a night too short to show a pattern. If a night came out wrong, you can correct the times or leave it out of your averages. WHAT YOU GET EVERY MORNING • Sleep score with the full formula shown — no hidden weighting • Sleep stages across the night: deep, REM, light, awake • How long you took to fall asleep, and your sleep efficiency • Snoring detection with recordings you can listen back to • Room noise in decibels FROM APPLE HEALTH Heart rate and its overnight dip, HRV, blood oxygen, breathing rate and wrist temperature — each shown next to your own weekly average, with a plain answer to whether it is normal for you. WAKE UP GENTLY The smart alarm looks for a light sleep phase inside your wake window, so you are not pulled out of deep sleep. If no light phase comes, it still rings at your latest wake-up time. That time is a guarantee, not a suggestion. ON YOUR WRIST AND HOME SCREEN Start or end the night from the Apple Watch app. Widgets show last night's score on the home and lock screen. A Live Activity keeps the running night on your lock screen, so you always know it is recording. STILL EVERY SLEEP SOUND Rain, waves, fire, white noise, city and nature — mix up to eight sounds, save your own mixes, set a fade-out timer. Nothing from the sound library was removed. FREE TO TRACK Recording your night, the score, the stages and the vitals are free and unlimited. Premium adds history beyond 14 days and widgets. PRIVACY Night recordings stay on your iPhone and are never uploaded. No third-party analytics, no advertising, no account.

Quitter App

Being a quitter is the whole point. Pick what you are quitting, press start, and Quitter walks you through withdrawal one honest day at a time: what today will probably feel like, why, what helps, and exactly when it gets easier. EIGHT WAYS TO QUIT Weed, cigarettes, vaping, alcohol, caffeine, sugar and social media each come with a researched day-by-day timeline. Or create a custom quit with its own name for anything else you want to put down. A REAL TIMELINE, NOT A PEP TALK Every phase of every plan tells you three things you can scan in seconds: • What to expect. The symptoms that are normal right now, so nothing feels like an emergency. • What helps. The moves that actually shorten the hard days. • What to skip. The traps people fall into at exactly this point. And you can read the whole road ahead in advance, so a bad day always has an end date. A SLIP IS NOT A RESET Your streak restarts, but your lifetime clean days, your longest streak and your savings are never erased. Quitter is built on how quitting actually works: attempt five is not failure, attempt five is the method. FOR THE HARD TEN MINUTES The Craving SOS screen gives you a breathing ball to follow, a five minute urge-surfing timer, and over a hundred short encouragements, with your own reasons for quitting dealt back to you at the exact moment you need them. HELP IS ONE TAP AWAY The home screen widget doubles as a panic button: tap it and you are already on the breathing screen. No unlocking, no navigating, no willpower spent finding the right button. There is a Craving now shortcut on the app icon too. EVERY WIN COUNTS, NOT JUST THE SLIPS Ride out a craving and Quitter quietly counts it. Most apps only ever record your failures; this one keeps score of the fights you won, and that number never goes down. WATCH THE NUMBERS GROW • Clean days, months and years, counted from your quit moment • Money saved, based on what the habit really cost you • Time reclaimed, for habits that ate hours instead of dollars • Milestones from 24 hours to one year, each celebrated once FEEL IT GETTING BETTER A one-tap daily mood check-in builds a graph that quietly climbs. On the days you doubt yourself, the line does the arguing. TALK IT OUT On iPhones with Apple Intelligence, ask the on-device companion anything about your quit. It knows what you are quitting and what day you are on, and it answers like a steady friend. The conversation never leaves your phone. PRIVATE BY DESIGN No account. No cloud. No analytics. No ads. Notifications never name your habit, not even with an emoji, because lock screens are semi-public. The widget shows just an emoji and a day count. What you are quitting is nobody's business but yours. FREE MEANS FREE No price, no ads, no subscription, no locked features, and nothing about you is collected or sold. You are trying to quit something; the app should not be another thing with its hand out. A note on safety: Quitter offers encouragement and general information, not medical advice. If you drink heavily every day, withdrawal can be medically dangerous. Please talk to a doctor before stopping suddenly.
