Why track wear time
22 hours worn leaves just 2 hours for everything else.
Orthodontists and aligner makers usually ask for 20 to 22 hours of wear a day. Meals, coffee and brushing add up faster than you think, and a few long breaks a week can leave a tray that doesn't fit. A wear time tracker shows you the real number instead of a guess.
Know your out-time budget
The app counts down the out-time you have left today, so you can see whether there's room for that long lunch. How long can aligners be out?
Switch trays on the right day
Seven days, ten or fourteen: set each tray's length and get a reminder on change day. When to switch aligner trays
