Armchair Traveler: Tripda for iOS, Google Play Connects passengers and drivers to share rides and expenses in 13 countries, including the U.S., Argentina, Brazil, Chile, Colombia, India, the Philippines, Uruguay and more. Female drivers and passengers who are concerned about safety can select a “ladies only” option. What’s not: I wanted to see which rides I was missing out on but couldn’t find them anywhere. [...] I’d like to see the rides people are offering from my general area in the near future.
