Travel planning app
Joornie is a travel app that I wish I had while doing road trips through the US and Eastern Europe.
The main issue I faced is when looking at new places is that blogs and travel books just want to dump all information available. That's what best for their SEO and to be able to claim to be the most complete. Instead, I want to provide a curated resource that offers people advice rather then just all the available options.
For instance, it's not recommended to use Airbnb in Bosnia. Rather, Booking.com homes is much more popular and affordable. Or, did you know that instead of taking a Bosphorus cruise in Istanbul you can a better experience using the public transport ferry at about one tenth the cost. These are my specific recommendations to what you should do.
