Nextdoor is a community-building app for those who live in your area. Available for download free of charge, this social networking tool will let you bond with your neighbors quickly and conveniently. Using your smart phone's location services, the app will track your district and the users within it -- this then creates a private platform for your group to post announcements and photos. From organizing a crime watch unit to finding a babysitter to spreading the word about a lost pet, the app serves great social causes.

Today's urban lifestyle makes it hard to get to know our neighbors. Attempting to bring back tight-knit community bonds, Nextdoor provides an opportunity for you and nearby residents to discuss important matters. The motive behind the creation of this app is heart-warming: "When neighbors start talking, good things happen."
