Project Summary

MobiDev built a web app and native iOS and Android mobile apps for a music score library, including a PDF viewer, real-time social features, and subscription/payment handling. The iOS app used Swift, PDFKit, and Core Data while Android development used Kotlin; the vendor recommended a new large mobile database that improved app speed. The apps have received strong user ratings and the engagement (started July 2017) is ongoing.
