UpToUs for iPhone
Open iTunes to buy and download apps.
UpToUs for iPhone lets you keep up to date with all of your UpToUs communities. Find contact information for other members and contact them by phone, text, or email. Check signup lists to track snack schedules, volunteering and other activities. Check your calendar for upcoming events. View and post announcements.
We use this for our team communication. It's useful and most importantly, it's simple! I like how interactive this site is, and the tech support is quick and efficient!
Worse than the first LinkedIn app
Of course, the site is no comparison to the first LinkedIn to start with.
