Hybrid app
An app that is really a web page in a native shell — one codebase for every platform, at the cost of feeling like a web page.
The appeal is obvious: the web developers you already have can build the app, and fixes ship without store review because the content loads from the server. The bridge to native code gives access to camera, contacts and notifications that an ordinary web page lacks.
The criticism concerns details that are hard to imitate: scroll momentum, transition animations, how the keyboard pushes the view. Facebook abandoned its hybrid app in 2012, calling it their biggest mistake. The boundary has blurred since — React Native and Flutter are not hybrids in this sense, since they draw genuine native views.
