So there are LOTS of great travel apps out there, like Tripit (to tame all those wild, travel-related emails and cage them in a single itinerary) and Kayak (to research alternatives to that canceled flight!), but my current favorite is WhatsApp.

One of my pet peeves is being hit up for international texting charges, both when I’m traveling, and when I’m home and just want to exchange a quick text with a friend or relative overseas. And even more frustrating than the 50c per text charge, is the fact that I often don’t even receive the texts I’m sent. So I send a text, wait for a response, and wait… and wait… Grrr!

Yes, it’s not even a ‘real’ travel app, but WhatsApp allows me to exchange texts for free with friends on non US networks, at no charge, with no delivery issues.  And when I’m traveling I can use it over WiFi and not incur any data roaming charges. And I can even attach photos… What’s not to love?

Found a travel app you just love? Do tell…
