Now njump.me shows a list of selected Android/IOS apps on mobile, along with the usual web clients. So you can quickly switch app and don't be trapped by the default association.
For newcomers this permits also to discover new apps; in fact, if an app is not installed, the user is redirected to the configured apps store where he can preview it and learn more.
As usual, Njump remember your most used apps and show them in order; the favorite is only one click away, without opening the menu.
