You are planning on taking an active vacation by visiting a foreign city and touring its sights. How much will it cost per day?
An app that lets you choose a city, the activity level (how many museums, sites, etc. you would like to visit per day), eating habits (how many hot meals, etc.), and where will you stay (to calculate travel expenses), and gives you a from-to list of expense possibilities for each item.
Has this ever happened to you? You return from a vacation and don’t remember what you did on what day.
An app that alerts you whenever you arrive at a place to take a photo and caption it, and when you leave alerts you to write a short note (text or audio) about the place you just visited. At the end of the trip, you have a textual and visual timeline that you can export as a video, an HTML page, etc.
You are about to fly for a vacation and realized you don’t know enough about your destination.
Sell small cheap tablets at airports that have comprehensive written and video information about destinations, plus a GPS navigation software. You pick up the tablet with your destination or have multiple destinations uploaded to the tablet on the spot in minutes, and when you finish your vacation, you still have a tablet you can use for other things. You can also sell internet access packages to include with the tablet for the destination mobile system.
