A true "native" app stores a copy of all its data on the user's device so it can work when there is no internet or even phone connection.
"Web-based"apps in fact are little more than a mini-website. No connection, no go.
Web-based apps have been used because they are cheaper and it's easier to update the data. Every time a user calls data, it is downloaded from the internet.
H-DAM is the best of both worlds.
H-DAM is a true native app, storing a full data copy on the user's device. That means the app is fully functional even if there is no internet connection, or even no phone connection.
But updates are from the master data copy stored in our cloud Data-vault. Updates (and data transfer from users) can happen whenever there is a connection, and only the changed data is transferred.
