Pada pembuatan aplikasi menggunakan metode pendekatan software waterfall dan menggunakan pemodelan Use Case serta Class Diagram dalam perancangan aplikasi. Aplikasi dibangun menggunakan framework React Native dan framework Laravel dan diuji menggunakan metode blackbox testing dan aplikasi telah berhasil dirancang bangun dan berhasil di uji coba dengan hasil sesuai dengan yang diharapkan. Untuk mengetahui tingkat kemudahan penggunaan sistem dilakukan dengan metode Usability testing dan didapatkan hasil sangat baik. Kata Kunci : Lukisan Wayang Kamasan, Aplikasi Android, Kode QR AbstractKamasan puppet painting is one of the handicrafts that is a Balinese cultural heritage.
