Experience

Arkantos

https://github.com/njrafi/Arkantos
I developed a hobby Android application for browsing and searching video games.

The app fetches game information from the server and shows it on the UI. It currently has four screens (home, genre, game details, and favorite games). The home page contains one carousel showing the 15 most popular games and eight game containers showing games filtered by genre. The genre page shows all games filtered by that genre. The game details page shows the game name, cover, release dates, and summary. Games can be marked as "favorite" on this screen. The favorite games page shows all games favorited by the user. The favorite games are stored in a local database. Removing the app will remove favorite games as well.
