Experience
Avoid Town
Cruise ships visit the Cayman Islands on a regular basis and the thousands of passengers they bring in every day are an important part of the islands' tourism product. However, for residents, lots of ships also means loads of traffic downtown.
Wouldn’t it be nice if you could check how busy town was going to be? And if you’re in a rush, maybe you should avoid town entirely? There should be an app for that, right?
Yep, we thought so too! Check Avoid Town before you leave and don't get caught out again.

Bliss Yoga

Brainfeed
Brainfeed is an educational iPad app made for kids 7+ years old. Behind the scenes, a team sifts through the massive amounts of video available on the web and curates the very best of educational video that is both age-appropriate and curriculum based.
