TV-Browser for Android is an EPG (electronic program guide, NOT FOR WATCHING TV) with more than 400 TV and radio channels mostly from Germany, Austria, Switzerland, Denmark and Poland (additional some from other countries). The data will be downloaded from the Internet (maximum three weeks ahead) at a user selected time. The data is then ad-free and off-line available.
Different views are giving you a good overview of the programs, you can add programs to the calendar, search for programs and create Favorite programs.
P.S.: It would be nice if you contact me when you ran into problems before giving a bad rating for the app.
