We only count the time they're out.
Traybook is a wear-time log for clear aligners and retainers. Take them out for a meal, tap once. Put them back in, tap once. Your daily wear time adds up on its own. No sign-up. No ads — not one, even on the free version.
■ Two taps a day
Tap Take out when you eat or brush, and Put in when they go back. Forgot to tap? Fix the times afterwards, or add a whole period from scratch. Overlapping entries are merged for you.
■ A ring that is one whole day
The circle is 24 hours, and the arc grows with the time you wore them. A single notch marks your goal. The arc keeps growing past the goal, so 22 hours and 24 hours never look the same.
■ Progress photos, no limit
Front, side, upper, lower. Your previous shot from the same angle is overlaid faintly so every photo lines up. Take as many as you like — they stay on your device and never reach the Photos app.
■ Retention mode
When you move to a retainer, numbered tray changes stop and the daily goal switches to a default suited to night-time wear.
■ One page for the clinic
Show your wear time in three seconds at your next appointment (Pro).
Free: wear-time logging, fixing entries afterwards, unlimited progress photos, comparisons, aligner numbers and change dates, a reminder when they are left out, retention mode, and the last 90 days of charts.
Pro (a one-time purchase, no subscription): the full chart history, off-time patterns by weekday and hour, the clinic PDF, CSV export, cost tracking, and automatic backups.
Note: this is a log for wear time and photos. It gives no diagnosis and no treatment instructions. The daily goal is a value you set yourself, not something the app recommends. Ask your dentist about how your treatment is progressing and when it will end.
