Aligner tracker: how much out-time you have left today

Because the decision is about the time out. “Worn 19 hours today” is a result you can no longer change; “35 minutes left” answers the question of whether you can still have that coffee before putting them back. With a 22-hour goal the budget is two hours a day, and all meals and cleaning have to fit in it — seeing the remainder as a number makes people noticeably more likely to fit.

Fix the interval — there is a “Fix” button on every removal from today, and an unusually long interval is caught and queried by the tool immediately, while you still remember how it went. This is not falsification: the point of tracking is to know your real wear time, not to have pretty numbers. Trackers where editing is impossible simply get abandoned after the first forgotten press.

No, and this differs from how people usually think about it. Teeth move while the tray grips them tightly and pushes in the intended direction; every removal lets them drift back a little. “Total hours per week” is not the quantity that matters — continuity is. So a shortfall yesterday is not made up by extra effort today; it shows up in whether the next tray seats properly.

Do not, and see your orthodontist. A tray that will not seat completely means a tooth has not reached the position that was planned: the next tray is calculated for that new position and will seat even worse. The discrepancy then accumulates, and it usually ends in an extra refinement stage. Sometimes the clinician asks you to stay on the current tray longer, sometimes to step back one; that call is theirs.

Yes, the history is kept in this browser on this device and survives closing the tab and reloading. It does not travel between phone and computer, so keep the record on one device — usually the phone, which is in your hand at the moment you take them out. Clearing site data in browser settings erases the history.

Usually between 7 and 14, and your orthodontist decides: the interval depends on how much movement is built into that step, on your age and on bone density. That is why the number in the settings is yours rather than ours. Trays are normally changed in the evening, before sleep: a new tray sits tightly and presses a little for the first few hours, and that period passes less noticeably overnight.
