Who is Hot? has recently been updated so I thought I’d write about it. We did a little review of it on an iPhone 101 Episode but here’s a little more in depth review. First, I must tell you this is a weather app. I know the title may seem to suggest otherwise but this app has to do with temperature, not looks It takes all your contacts and based on their location, gives you their current temperature. With the previous version, this was based on address only but the new version also takes info from the first 6 numbers of your phone number, which includes the area code, to determine your location. Just remember that if you have a friend or family that has a cell phone from one city and has moved to another and kept their number this might make things less accurate.

When you first open the app it brings you to a list of your contacts sorted by name. The first contact is yourself; tap it to update your location. Across the bottom you can sort the list by first or last name, temperature, or distance from your current location. There is a nice scroll bar section on the right that will scroll you through your contacts faster by letter, temperature range or distance range. Each contact shows lots of info including an icon representing current conditions, city, state, and country, distance from current location, temperature and their picture. You can also tap the person’s name to see their contact info, or tap the current conditions icon for more details about their current weather from the Weather Underground iPhone formatted website right in the app.

The little “i” in the bottom right corner takes you to settings where you can turn off the feature that detects location by phone number. You can also switch to metrics. There is a scroll wheel at the top so you can pick which contacts the app uses. I can only see “All Contacts” so I’m assuming this works only with Exchange type contact lists. The applications seems to be getting a little cluttered but is still a fun little app.

Last but not least, you an tap the Weather Underground logo in the upper right corner to go to their iPhone optimized website right inside the app.
