Yakadir is a unique iPhone application developed by HEROIC SANTE, falling under the Lifestyle category. It revolutionizes the way opinions are valued by converting them into practical projects and monetary rewards. Users can share their thoughts or personal experiences related to the French healthcare system and earn points that can be used to fund various projects. With each contribution, users accumulate "yakas" that can be later converted into direct bank transfers.

Yakadir offers flexibility in expressing opinions either verbally or in writing, ensuring user anonymity and no mandatory account creation. The app, which is free to use, encourages active participation in sharing feedback. Moreover, Yakadir plays a civic role by forwarding relevant information to healthcare stakeholders to drive positive changes in the healthcare system.
