Chrono Dents is an iPhone application designed to help users control the duration of their toothbrushing. With a built-in timer, users can set it for either 2 or 3 minutes to ensure a thorough cleaning.

But what sets Chrono Dents apart is its unique feature of providing accompanying activities during toothbrushing. Users have the option to watch YouTube videos, such as live music performances, magic tricks, or children's songs. Alternatively, they can listen to popular national radio stations like France Info, Chérie FM, or Fun Radio. The app even offers the ability to listen to songs from up-and-coming artists.

To motivate children to brush their teeth twice a day, Chrono Dents incorporates a star rating system. This feature rewards children with stars for each successful brushing session, encouraging a healthy dental routine.

In addition, Chrono Dents includes a "weekly summary" mode that allows users to track the brushing habits of each family member. This feature provides a visual representation of the days when teeth were brushed, helping families monitor their oral hygiene.

Chrono Dents is a free application available on the iPhone platform, making it accessible to a wide range of users. With its toothbrushing timer, engaging activities, and family tracking feature, Chrono Dents aims to make dental hygiene a fun and interactive experience.
