Wanderlust is a travel budget and expense tracking app just launched on the Google Play Store. Create a trip, set a budget, record your expenses and see a graphical breakdown by category, country or time period. Tag expense locations and display them on a map.
Finding a simple expense tracker that didn't tangle up business, flight schedules, and lodging was hard. I can do that. I'm glad I found Wanderlust as a simple expense tracking that sync's across tablets and my cell.
I'm looking forward to a web-based version sometime soon.
