Smilo is the aligner tracker that makes wearing your clear aligners effortless. Built for Invisalign, ClearCorrect, Byte, Spark, Angel Aligner, SureSmile, Candid Pro, 3M Clarity Aligners, Impress Aligners and all other clear aligner brands. Smilo gives you one beautiful place to track your wear time, manage your trays, and watch your smile transform. THE TIMER THAT ACTUALLY WORKS Tap to start. Tap to stop. That's it. A satisfying progress ring fills as you hit your daily wear goal — whether your orthodontist recommends 20, 22, or custom hours. See your daily compliance at a glance, with live sessions tracked to the second. TRAY TRACKING DONE RIGHT Know exactly which tray you're on, how many days you've been wearing it, and when to switch. Your orthodontist's recommendation is your guide — but life happens. Smilo lets you switch early when the fit is right, or delay by a day or two when you need more time. No rigid deadlines. Treatment that works with your reality. CLINICAL-GRADE PROGRESS PHOTOS Capture your smile transformation with Smilo's guided camera. An oval teeth guide and crosshair overlay keep every photo framed consistently — so your progress photos actually look like progress. A soft screen flash gives you clean, even lighting every time. Metadata (date, day, tray number) is stamped directly on every photo. SMART REMINDERS THAT MAKE SENSE Smilo reminds you at the right moments — after meals, at the end of the day, on tray switch day — with messages that reflect what's actually happening in your treatment. No generic alerts. No notifications that make no sense at 10pm. COMPLIANCE CALENDAR See your full treatment history on a colour-coded calendar. Green for days you hit your goal. Amber for partial days. A streak counter keeps you motivated to stay consistent. HOME SCREEN WIDGETS Glance at your wear time, tray number, and switch countdown without opening the app. Smilo's widgets update in real time and look beautiful on any home screen. WORKS WITH ALL ALIGNERS Invisalign, ClearCorrect, Byte, Spark, Candid, SureSmile, Angel Aligner, 3M Clarity, Candid Pro, 3M Clarity Aligners, Impress Aligners or any custom lab aligner — Smilo works with every clear aligner brand and every orthodontic practice. RECOMMENDED BY DENTAL PROFESSIONALS Smilo is used and recommended by orthodontists and dentists who want their patients to complete treatment on time, with consistent wear, and without the frustration of clunky apps. TRAY CARE MADE SIMPLE Keep your aligners clean and your care routine consistent with Smilo’s dedicated tray-care section. Log each cleaning session, see when your aligners were last cleaned, and build better habits throughout treatment—all without needing a separate reminder or notes app. THEMES THAT FEEL LIKE YOU Personalise Smilo with a selection of beautifully designed themes. Choose the appearance that matches your style and switch themes whenever you like, while keeping the same clear, distraction-free tracking experience. DARK MODE SUPPORT Choose the appearance that feels best to you and change it anytime from inside the app. Support for both light and dark modes. No account required. No sync required. Your data stays on your device. Disclaimer: Smilo offers a free trial. Full access requires a Smilo Pro subscription. Smilo Pro is an auto-renewable subscription.

Works with Invisalign, Angel Aligner, Spark, ClearCorrect, Byte, and any other clear aligner. A BUDGET, NOT A STOPWATCH A stopwatch leaves you to do the math. OutTime gives you a daily out-time budget and counts it down every time your aligners come out. Tap once when your aligners come out, tap again when they go back in. SEE WHERE YOUR OUT-TIME GOES Where do your two hours go? OutTime sorts your sessions into Food, Drink, Meetings, and more, with your session count, average, and longest. See your 7-day average next to last week's, and days on budget for every tray. Tap any day in the month calendar to see that day's sessions, or log one you forgot. With Pro, share a clean Wear-Time Summary PDF of any month, plus your session data as CSV, ready for your next appointment. PRO: ON YOUR WRIST AND HOME SCREEN Start and end sessions from your Apple Watch, and see your remaining out-time on your wrist. Home Screen widgets show it all day. While your aligners are out, the countdown also runs on your Lock Screen. FORGOT TO START THE TIMER? Edit any session after the fact: adjust the time or duration, or log a session you missed entirely. Life happens; your data should still be accurate. HANDS-FREE WITH SIRI Hands full at lunch? Say "Take my aligners out with OutTime" to start a session, or "Put my aligners back in with OutTime" to end it. Works with Shortcuts and the Action Button too. YOUR DATA STAYS YOURS No account.

We mean it. SMILE TIMELINE Build a private photo timeline of your smile, tray by tray. Crop, straighten, rotate, and brighten each photo. Put any two side by side and share them, or turn the whole timeline into an MP4 timelapse video. Your first photo is free. Pro unlocks the rest. RETAINER MODE Treatment ends, but retainers do not. Pick "I wear a retainer" on first launch, or switch later. Full-time or nights-only wear, with its own bedtime and replacement reminders. MADE BY ONE DEVELOPER No investors, no ads, no data sold.
