Aliner makes wearing aligners calmer: a timer, a journal and honest stats in one beautiful app. No ads, no tracking. ONE-TAP TIMER Take your aligners out β€” tap the ring. Aliner counts aligners-out time reliably in the background: it survives restarts, time-zone changes and long flights. The lunch reminder tells you when to put them back in. TRAYS & CALENDAR Your current tray, change day and appointments at a glance. Tray-change reminders arrive on their own. GUILT-FREE STATS Day, week, month. Aliner celebrates progress instead of lecturing you: every hour of wear counts. A PHOTO DIARY FOR YOUR SMILE A camera with a framing guide and manual crop keep every photo in the same format. Before/after comparison and a full-course timelapse β€” free and unlimited. Photos stay yours: on device and in your personal iCloud. JOURNAL & AI SUMMARY Tagged notes build an automatic β€œask the doctor” list. The AI summary (Aliner+) turns weeks of notes into one short list for your appointment β€” only with your explicit consent, and photos are never sent. ALINER+ β€” ONE SUBSCRIPTION Widgets and Live Activity, an Apple Watch app, Siri shortcuts, unlimited photo cloud and the AI summary. The yearly plan starts with 7 days free. Everything else β€” timer, calendar, stats, photo diary, before/after, timelapse, notes β€” is free forever. PRIVACY, HONESTLY No ads. No tracking. Photos never leave your iCloud. Aliner shows only your own data and gives no medical recommendations β€” treatment questions belong to your doctor. Terms: nikibstudio.site/terms Β· Privacy: nikibstudio.site/apps/aline/privacy

About

Tray Harder

Read full description

Tray Harder is the focused, privacy-first wear tracker for clear aligner treatment β€” 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 β€’ No account. No cloud. No analytics. Your treatment data, photos, and preferences live only on your phone. β€’ A warm, calm aesthetic β€” built to feel like a quiet companion, not a clinical medical app. β€’ 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 β€” total trays, days per tray, daily wear goal β€” 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 β€” just the right nudge at the right time. Each reminder is independently toggleable. SEE YOUR PROGRESS β€’ A monthly calendar view shows your compliance at a glance β€” green for goal hit, amber for close, red for missed. β€’ Tap any day to see every break session and edit anything that's wrong. β€’ A weekly view shows your average wear time and the past 7 days as quick bars. CAPTURE YOUR SMILE STORY β€’ Take weekly progress photos with a built-in alignment guide. β€’ Compare any two trays side by side with a draggable slider. β€’ Watch your full journey play back as an animated timelapse. β€’ Import photos you've already taken β€” 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.
