  • Feedback


Look and feel of the app is neither very great nor very bad, it can be called just okay. When I run the app for first time after installing, it asked for registration i.e. Name, Mobile and Email. I think registration details should not be mandatory as I doubt many people will exit the app at this point. I myself has put some garbage values as I did not feel any need to give my personal information to the app. I liked the Venue section of the app much as it gives details of the halls and what’s inside the hall. Pragati Maidan is very big area and the app helped me in finding the hall and stalls of my interest.


Overall the app is good. I would recommend you to install the app if you are planning to attend the New Delhi World Book Fair.

I myself have started learning French since last week on my Android mobile. I only give 10-15 minutes a day and have covered 2 lessons and learned 12 French words. It’s a nice feeling to learn a new language without worrying much about time and money. I would highly recommend Duolingo.

Duolingo iOS application can be run on iPhone, iPod Touch and iPad. Android app at present is compatible with phones while a tablet version is coming soon.
