The anime personifies the app’s customization engine as three “Hacka Dolls” — the personal entertainment AI and main navigator Hacka Doll #1 (played by Miyu Takagi), the anime expert Hacka Doll #2 (Kaya Okuno), and the knowledgeable otaku Hacka Doll #3 (Nanami Yamashita).
The app inspired a television anime titled Hacka Doll the Animation in 2015.
The official blog of DeNA’s Hacka Doll app announced on Wednesday that it will end service on August 15, with a final version update scheduled for later this month.
The app delivers a customized feed of news for each user.
