Dear Mr. Shaik.
First of all, congratulations on this achievement. I downloaded the app and the first impression is that it is super-fast. (9MB!) The first screen shows how you want to log in: Steemconnect or FB. Is assume most people who are interested in this still don't know what STEEM is. Maybe put a link below with: "What is STEEM" with some Q&A on that page? Explaining the benefits of using the blockchain to post your content. I think you would be the first Dapp on the chain that does that.

I like how you use the word sustainable a couple of times. This is also not very common in an environment where most people think short-minded. To tackle the 'no revenue´ first months and to create an instant income; why not integrate affiliate links on some destinations? If people create a waypoint, they have an option to include the Tour/activity/excursion that they did over there. Like, miss @livinguktaiwan went on a booze cruise on PhiPhi Island, she adds the affiliate link which she can select from a menu based on the destination. You get a commission each time another traveller wants to have the same experience as her. (this is what you sell basically, an experience)

You can even take this one step further and give the author a percentage of the income her post makes by tracking the outgoing link from that post. This way the author is incentivised to make amazing content because the more people see her post, the more she can earn in perpetuity, not only the first 7 days of her posting. Partners to work with (I work with them in real life) GetYourGuide - Booking - Viator, but I am sure there are more in the world, I just don't need others.

I wish you loads of success
