Build lasting habits with an app that learns how you tick. AttuneHabits doesn't just track what you did — it predicts when you're about to slip and steps in at exactly the right moment. Using on-device machine learning, it builds a personal model of your behavior and delivers nudges that actually work. No cloud. No data leaving your phone. Just smarter habits. INTELLIGENT NUDGES, NOT DUMB TIMERS Most habit apps send reminders on a fixed schedule. AttuneHabits calculates a slip probability for every habit, every day, and makes a decision: - High risk + active streak? A streak warning breaks through Focus mode. - Moderate risk? A gentle reminder timed for when you're most likely to act. - Low risk? Nothing. You'll do it on your own. It even learns whether nudges help you or not — and adjusts accordingly. STREAK PROTECTION THAT ACTUALLY PROTECTS Your 30-day meditation streak matters. AttuneHabits doesn't just count it — it actively defends it. When it detects you're at risk of breaking a streak, it sends a Time Sensitive notification before you miss a day, not after. Milestone celebrations at 7, 30, and 100 days keep you motivated along the way. TRACK ANY KIND OF HABIT Whether you're trying to exercise more, drink more water, meditate daily, or cut back on social media — AttuneHabits adapts to you. - Binary habits: Meditate, journal, sleep early — tap to complete. - Count-based habits: Drink 8 glasses of water, read 20 pages — increment through the day with a built-in stepper. - Flexible scheduling: Daily, specific days (Mon/Wed/Fri), or a weekly target (3x per week). BEAUTIFUL PROGRESS VISUALIZATION Every habit gets a GitHub-style contribution grid — a color-coded heat map showing your consistency over months at a glance. Count-based habits show intensity gradients so you can see partial vs full effort. The Progress dashboard includes completion rate charts, active streak rankings, and a monthly calendar heat map across all your habits. TWO WAYS TO VIEW YOUR DAY - Card View: Rich cards with embedded contribution grids and streak badges. - Week View: Compact spreadsheet with 7 days of history. Tap any cell to toggle. Both views designed with iOS 26 Liquid Glass for a premium, native feel. COMPLETE HABITS WITHOUT OPENING THE APP - Tap "Mark Complete" right from the notification on your lock screen. - Ask Siri: "Mark Meditate as done in Attune." - Tap a habit in the home screen widget. Three widget sizes show your daily progress, habit list, and streak counts. GETS SMARTER OVER TIME AttuneHabits starts with proven heuristics from day one. Once you've built enough history, a machine learning model takes over — trained entirely on your device using Apple's CreateML. The more you use it, the better it understands: - Which days you need a push and which you don't - Whether weekends need different treatment - What type of encouragement works for you - Which habits are rock-solid and which need support MAKE IT YOURS - Choose from 33 icons and 18 accent colors per habit - Set a global theme: System, Light, or Dark - Pick a global accent color - Configure quiet hours and daily nudge budgets - Export your data as JSON anytime. Import it on a new device. Share beautifully rendered progress cards to Messages, Instagram, or anywhere else. PRIVACY YOU CAN TRUST - 100% on-device: no servers, no analytics, no tracking - No account required - ML training runs locally on your iPhone - Your habit data never leaves your phone. Period. Download AttuneHabits and start building habits that stick — with an app that's paying attention even when you're not.
