WITH FIXU YOU CAN: • One-tap tracking — mark aligners as on or off in seconds • See your real-time daily compliance percentage toward your goal • Build a streak of consecutive days hitting your target • Get smart reminders when you’ve been without your aligners too long • View your full history in a color-coded monthly calendar • Manually log past days if you forgot to track • Document your smile journey with progress PHOTOS and before/after comparisons • Add notes to any day to track how your treatment is going • Track your full treatment plan — current aligner, complete timeline, and estimated end date • Use the home screen widget to check your progress and toggle status without opening the app TRACK YOUR FULL TREATMENT: Set up your treatment plan — total aligners, days per aligner, and your start date — and Fixu handles the rest. See which aligner you’re on, how many days you’ve been wearing it, and when it’s time to switch. A full timeline shows every aligner with its date, whether completed, current, or upcoming. PROGRESS PHOTOS & COMPARISON: Take photos directly in the app or upload from your photo library. Use the built-in side-by-side comparison to visualize your treatment progress over time. REMINDERS THAT ACTUALLY WORK: Fixu alerts you at 30 minutes, 1 hour, and 2 hours without your aligners. Long press the notification to log that you’ve put them back on — no need to open the app. YOUR PROGRESS, VISUALIZED: The monthly calendar shows green for days you hit your goal, orange for partial days, and red for days with no data. See how your treatment is going at a glance. EASY MIGRATION: Already tracking in another app? Import your full history into Fixu and continue right where you left off. YOUR DATA, YOUR CONTROL: Your treatment data is private. You can delete your account and all your data directly from within the app, at any time.

Tray Harder is the focused, privacy-first wear tracker for clear aligner treatment — Invisalign, SureSmile, ClearCorrect, Spark, Byte, and any other clear aligner system. It helps you hit your 22-hour daily wear goal, stay on schedule, and watch your smile transform tray by tray. WHY TRAY HARDER • No account. No cloud. No analytics. Your treatment data, photos, and preferences live only on your phone. • A warm, calm aesthetic — built to feel like a quiet companion, not a clinical medical app. • Designed by someone who's been through clear aligner treatment. TRACK YOUR WEAR TIME Tap when you take your aligners out, tap when you put them back in. Tray Harder's elegant ring shows your daily progress toward your wear goal, with a live timer when they're out so you know exactly how long you've been on a break. Forgot to track a session? Log past breaks in seconds. STAY ON YOUR TRAY SCHEDULE See which tray you're on, how many days remain until your next switch, and how far along you are. Tray Harder calculates everything from your orthodontist's plan — total trays, days per tray, daily wear goal — and remembers when you started. GENTLE REMINDERS Optional notifications nudge you to put your aligners back in after meals, remind you on tray-switch days the night before, and check in at bedtime. No spam — just the right nudge at the right time. Each reminder is independently toggleable. SEE YOUR PROGRESS • A monthly calendar view shows your compliance at a glance — green for goal hit, amber for close, red for missed. • Tap any day to see every break session and edit anything that's wrong. • A weekly view shows your average wear time and the past 7 days as quick bars. CAPTURE YOUR SMILE STORY • Take weekly progress photos with a built-in alignment guide. • Compare any two trays side by side with a draggable slider. • Watch your full journey play back as an animated timelapse. • Import photos you've already taken — they'll be tagged by tray. NEVER MISS AN APPOINTMENT Log upcoming orthodontist visits, see your next one right on the main screen, and get reminders so check-ups never sneak up on you. PRIVATE BY DESIGN There are no accounts to create. No cloud. No tracking. No ads. Delete all your data with one tap. Tray Harder is not medical advice. Always follow your orthodontist's instructions.
