Mihiluze is an Android application developed by Euskal Irrati Telebista that allows users to participate in the "Bai edo Bai" challenge, the final phase of the ETB1eko Mihiluze competition. Through this app, viewers will have the opportunity to participate from the comfort of their own homes.

The main objective of the competition is to have fun while improving one's Basque language skills and knowledge. Similar to the TV contestants who win cash prizes, users of this app can earn points. The app also allows users to compete against others in their household, friends, or family members. After each round of Mihiluze, users can check the overall rankings to see how many points they have earned individually or as part of a team.

At the end of each week, the user with the highest score will be rewarded with a prize. Mihiluze provides an interactive and entertaining experience for users to engage with the ETB1eko Mihiluze competition.
