I have been using this website latestgovtjobs.in and also using it's mobile app "Sarkari Naukri Updates App". I must say it's really a nice app. You should try it if you're looking for a government job in India. This app doesn't hang your phone or annoy by sending so many notifications. It's lite and doesn't kill phone battery or memory.
I have noticed that they keep every information for years so that we can check the previous exam dates, their syllabus etc.
Really Good Work!
