The iphone/ipad app works. Unfortunately, there is a problem with the android version. One user reported that it works with android 4.3. It does not work with android 4.2.2 or 4.4.2. When connecting to the card, a html status message is shown on the web page sayng Error 401 authorization required. This implies that the app does not present the default user name and the password which I used correctly. Google play says that the app is compatible with my seven android phones. This is wrong. None works with the app. However, the card is reached and works well with a web browser also from android phones so the app isn't really needed. Using a different port than 80 as an external port in port forwarding in the router, the card is reached with a web browser also over the internet.
