Free clear-aligner wear tracker for iPhone and Apple Watch
Alinear is a free companion for life with clear aligners. Tap when your trays come out, tap when they go back in: it tracks wear time, reminds you after 20 minutes out, and keeps your tray schedule. iPhone and Apple Watch. No account, no ads, your own iCloud.
Pace needs two or more snapshots. This launch has 1, so velocity and momentum read as unmeasured rather than zero.
A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
