Pretty much. Like you said, it's slow, drains battery and add a barrier to customer conversion. But also: Web apps don't have a direct access to the file system. Forget about filming or recording voice and saving that for anything serious. They can't respond to intents, making them completly isolated from the rest of the OS. They can't use the share function so your data is hard to extract, move around or ... well, share. They don't have access to the cryptographic facilities, or the authentification ones (e.g: no finger print unlock). They can't be directly filled in by other apps like lastpass. You can't even chose between security and convenience. The amount of data they can store is very limited, hard to manipulate, and the API changes from one browser to the other. Unless you have a bit of texte, though luck. Basically, anything that is not a simple CRUD service is useless offline, and slower online than the app version. Plus, how many people know that they can "add this app" to the home menu ? Not to say you should not offer a web version of your app. But it's an ersatz.
