矯正ログ / SmileProgress

Usage is simple.

1. Take a photo with your mouth open
2. Only the mouth area is automatically cropped out, excluding the face
3. You can compare with past photos in Before-After format

Whether you take photos daily or once a month, it's fine. They are automatically arranged in chronological order.
You can easily record daily changes during the orthodontic period, and you can also share them anonymously with the whole world.
