### 1/5 — Can’t use

*2019-08-23*

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

### 1/5 — Can’t even open the app

*2018-10-22*

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.

### 2/5 — Okay attempt but not great

*2013-07-27*

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?

### 1/5 — K

*2013-05-15*

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