9 essential travel apps you need to download before you leave home

Make sure you're fully prepared for any eventuality by downloading these apps before you head off on a trip. 

Making calls when you’re abroad can cost you a fortune. WhatsApp is pretty good for keeping in touch with people, and you can use it to call your contacts, but if you don’t have a stable internet connection, you’re out of luck. Rebtel doesn’t require internet to make calls – it uses local lines to make calls. This means an international call will only cost you as much as it would to make a local call. If the person you’re calling also uses Rebtel, the call is actually free. Handy.
