On my travels lately we have been using extensively a few apps which some of you may need or want when you travel as well. I am not so excited by any of the lame efforts of gamification, so ignoring this GAM (Game Spam) the apps are:
Everyone knows about WAZE and if you don't, go get it now and never get lost or late anywhere you drive.
Like WAZE, MOOVIT does for you bus users and train users what WAZE does for drivers. A bit confusing of a UI but once you get used to it you will not stop. It handles multiple language inputs as well. Very useful when visiting countries for conferences.
Google Maps, no link, it's on your phone already, yes the basic keeps getting better. We now say in Google we trust as it has bus details as well as traffic.
What's App also has been extremely helpful in helping us in discussions with friends and family, groups or individuals. Cell phone based, needs a phone number, but so much easier and less battery drain than Skype or almost any other IM.
Google Translate app is also extremely useful if you do not speak the local language.
How did we survive before? Well, when you live in the same place for over 10 years you may not have a need. When you move to a new country or just visit for a conference or vacation, best to have as much help, in your native language, as possible.
No doubt there are more useful ones, currency converters come to mind, and hopefully you will all provide more for me and others to look into as well.
