ONE TAP TO TRACK Tap when your aligners come out, tap when they go back in. See today's wear time, your progress toward your daily goal, and how many hours are left. Forgot to tap? Add or edit a session by hand. KNOW WHEN TO SWITCH TRAYS Enter how many aligners you have and how often you change them. The app shows which aligner you're on, which day of it, and when the next change is due, and it adjusts if you switch early or late.

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.

Verdict

The call

The clearest difference is review sentiment: Aligner at 100% against Smilo's 38%. Smilo's advantage is ads (none vs shown) and rating (4.5 vs 4.2). On price, ratings volume, update cadence and in-app purchases there is nothing between them.

Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Aligner sells 7 in-app purchases, starting at $2.99 per month and Smilo sells 6 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Smilo holds the better App Store score, 4.5 against 4.2. Both are backed by a comparable volume of ratings — 18 and 51 respectively. Written reviews complicate that: 100% of Aligner's written reviews are positive against 38% of Smilo's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Aligner ships an update every 2 weeks, Smilo every 3 weeks. Both last shipped on November 9, 2026.
