why do you think it's silly?
The offline functionality could have been implemented with the website too.
I don't see any benefit in this use case for an app. But it has the downside that an app has possibilities to screw my system or track me unnoticed. So if you do not need special native features and you are not a computationally expensive product, please built a good offline capable website and not an app.
Please tell me where the app has "it's uses" here?
