What's the best iOS app for tracking Invisalign wear time and progress?

My Invisalign is a specialized iOS app developed by Align Technology, Inc. for individuals undergoing Invisalign clear aligner treatment. It addresses the core needs of orthodontic patients by offering tools to ensure treatment adherence and visualize results. The app features a daily wear time tracker that logs hours aligners are worn, aiming for the recommended 22 hours per day. Users can set customizable reminders for tray changes, reducing the risk of missed transitions. A progress photo timeline allows for regular documentation of teeth movement, enabling side-by-side comparisons that motivate continued use. Real-world scenarios include busy adults relying on push notifications to reinsert aligners after meals or students using the photo feature to monitor aesthetic changes over months. Direct messaging with orthodontic providers facilitates quick consultations, potentially minimizing in-office visits. Reviews indicate strong user satisfaction, with many highlighting the app's intuitive design and effectiveness in maintaining routines. However, some users report occasional lag or slow scrolling after updates, which can impact messaging and navigation. Despite these performance quirks, the app remains a practical choice for Invisalign patients seeking structured support throughout their treatment journey.
