What You Might Want to Know
Which aligner brands does SmileDiary support?
SmileDiary supports all mainstream aligner brands including Invisalign, Angel Align, Smartee, and more. No matter which brand you use, SmileDiary can manage it.
Do I need to register? Is my data safe?
No account is needed. Your treatment data never reaches our servers: it stays on your device, and with a Pro subscription it is also synced to your own iCloud account. The app only sends anonymous crash reports and usage statistics, as described in the Privacy Policy.
What's the difference between Free and Pro versions?
The timer, calendar, photos and timeline, statistics, progress videos, export, and backups are all free, with no ads. Pro adds the Live Activity on the Dynamic Island and Lock Screen, Siri and Shortcuts, Home and Lock Screen widgets, the Apple Watch app, and iCloud sync.
How to ensure I meet my daily wear time requirement?
SmileDiary helps you record your daily wear time and sends reminders when approaching your set goal. You can set personalized wear goals and reminder times based on your doctor's recommendations to build good wearing habits.
Is the progress video a paid feature?
No. Progress videos are free for everyone: pick same-angle photos and the app turns them into a time-lapse with music, in portrait or landscape, ready to share.
What if I switch phones or delete the app by mistake?
Export all records and photos as a ZIP file from Settings and import it on the new device. The app also keeps automatic backups of its database. Pro users with iCloud sync on simply sign in to the same Apple ID on the new device.
Which devices are supported?
iPhone and iPad running iOS 17 or later. The Apple Watch app works alongside your iPhone.
Can I manage more than one treatment plan?
Yes. Set up separate plans for different phases, such as a refinement round, and switch between them at any time.
