User reviews

Can’t use

The app won’t let you finish the login page.

Can’t even open the app

Try to sign in and it goes to a blank page. Try to view stuff without logging in and you get nothing. Seems like I wasted my time.

Okay attempt but not great

Okay first attempt but needs more features.

Pro:

Ability to see scaled temp charts on the iPad. Ideally Hilton's would make this available by teaming with iNavx but they have not.

Con:
Nice to be able to create Waypoints but how do you save them? Am I missing something?

K

Does not work on iPhone 5. After logging in and clicking on the link to pull up the maps it closes.
