Travel Mate needs clarification that it's server-based (maybe with antifeatures)
The description of this application sounds like "the app" itself provides a number of "key features"; however, at least some, and possibly many, of these features are ultimately obtained from nonfree network services, such as "the current trend of the city on twitter can also be seen. (It is extracted from Twitter using Twitter and Yahoo! APIs)". It even lets you book hotels, which I doubt can be done via free services alone.
The other thing is potential tracking: the description made no mention of the fact that to use any of the app's features, I would have to "create a new account" on a server, with my "First name", "Last name", "Email id" and a password. This server, per se, appears to be hosted at https://github.com/project-travel-mate/server with the same license as the app, so NonFreeNet probably does not apply to it, but since it's claimed that the entire "platform basically uses a mash-up technology", and goes as far as providing "best music, novels, depending on the mood of the traveller", I cannot imagine how it would achieve this without tracking on the server side; and this tracking would be associated to my full name and email address.
So I think this app and its backend should be investigated more thoroughly, but even if in the end, neither NonFreeNet nor Tracking apply, I do believe the description should be updated to indicate this is a sign-up service, and not a standalone app.
