SmileDiary: The Private, No-Nonsense Tracker for Your Aligner Journey Tired of apps that want your data more than they want to help you? Finally, an app that genuinely respects your privacy and actually gets what it’s like to wear aligners. Created by someone on their own Invisalign journey, SmileDiary is the simple, secure companion your orthodontic investment deserves. Why SmileDiary Stands Out: • Truly Private: Your treatment data never reaches our servers. It stays on your device, and with a Pro subscription it is also synced to your own iCloud account. We never sell your personal information — only anonymous crash reports and anonymous usage statistics help us fix bugs and improve the app. • No Ads, Ever: A clean, focused experience with zero third-party advertisements. • No Registration Needed: Start tracking immediately—no email, no account, no commitment. • You Own Your Data: Full export functionality keeps you in complete control. • Multiple Treatment Plans: Manage different courses of aligners seamlessly. Your All-in-One Aligner Companion • Smart Wear Timer: One-tap tracking for removal time, real-time daily progress, customizable goals, and automatic statistics. • Visual Calendar: A color-coded view of your compliance, with notes for pain, attachments, or observations. • Progress Photos: Guided shots for 6 angles, organized by aligner number, with side-by-side comparison and a built-in editor. • Smile Timeline: replay your teeth's transformation angle by angle — drag or play through your whole journey. • Detailed Insights: Interactive charts show daily, weekly, and monthly trends. Track compliance rate, total days, and longest streaks. SmileDiary Pro Unlocks More: • Timelapse Video Export — turn your progress photos into a shareable vertical MP4 with background music, dates and aligner numbers. • Live Activity on the Dynamic Island & Lock Screen — a live removal timer with one-tap put-back. • Siri & Shortcuts — say "Remove aligner in SmileDiary" to log hands-free, with a built-in card in the Shortcuts app. • Home & Lock Screen Widgets for at-a-glance progress. • Full Apple Watch App — track right from your wrist. • iCloud Sync — seamless flow across all your Apple devices. Our Promise: Your journey, your data, under your control. SmileDiary is built on a simple belief: the details of your smile should be for your eyes only. Like a digital diary, it’s designed to serve you—not to serve you ads or mine your habits. A Note from the Developer: “As an actual aligner wearer, I couldn’t find a tracker that was both simple and truly private. So I built SmileDiary—the app I use every day. It’s just me behind this, not a big company. If it helps you on your journey too, please consider leaving a review!” ⎯⎯⎯⎯⎯ Privacy Policy: https://smilediary.app/en/app/smilediary/privacy/ Terms of Use: https://smilediary.app/en/app/smilediary/terms/
