One of the biggest worries for Americans traveling abroad is the fear of needing medical attention in a non-English-speaking country. HTH Worldwide, a health and safety services company, has a new mobile application to take care of that fear.

Dubbed mPassport, the subscription service has a database of some 4,200 English-speaking doctors and dentists in 180 countries as well as listings for more than 1,000 emergency care locations around the world, according to Mobile Marketer.

Geared towards vacationers, Americans living abroad, students and "globe trotters," mPassport works on any Web-enabled mobile phone. HTH charges $9.95 for 30 days, $15.95 for 60 days or $49.95 for a full year.
