DeNotes installs from your browser — there is no separate download and nothing to run. It takes one tap, and you can remove it the same way you would any other app.
On a browser that cannot install directly — Safari, Firefox — the button shows the steps for that browser instead.
Its own window
DeNotes opens like any other app, without tabs, a URL bar or the rest of the browser around your writing.
On your dock or home screen
It gets an icon where you expect one, and opens straight into your workspace.
Works offline
Notes you have open stay readable and writable without a connection, and sync when you are back.
Always current
There is nothing to update. Every launch is the latest version, because it is the same app the browser loads.
