mTrip plans your daily itinerary when you tell it what city you’re visiting, where you’re staying, and what you hope to fit in. There’s a $6 app for each of the 28 cities the service covers, but no roaming charges apply. An “augmented reality” feature uses your phone’s camera to highlight points of interest you might’ve overlooked. (Android, iPhone)
Telicost-Lite helps you avoid overage charges while traveling. It monitors your phone use and alerts you when you’re being charged for roaming or approaching your plan’s monthly limits. (Android, BlackBerry, iPhone)
