HTML5 was touted as the panacea of mobile app development back in 2012 (IIRC). The big news was when companies like Facebook and Linkedin migrated their iOS/Android apps to HTML5. Only problem is that the big name companies have since ditched their HTML5 mobile apps and gone back to using native APIs. They cite performance issues (apps running out of memory and stuttery animation) as the reasons for the switch. This is not just limited to the big companies, and others are leaving the HTML5 mobile app boat.
