As a college student, I can assure you that looking for a house to rent in a college town is wicked hard. Even with using apps like Craigsphone on my HTC EVO 4G, replying to a Craigslist post as soon as possible is still difficult.
Or at least it was until I found Craigslist Notification. This handy app will push updates to your EVO, letting you know when specific listings are posted. If you aren't looking to rent a place for the next school year, it can help notify you about free couches, job listings, rare items . . . it's up to you!
Craigslist Notification lets you enter in very specific searches and then will collect the relevant posts and push a notification to you when an item is posted.
Whatever your reason for needing up-to-the minute updates, Craigslist Notification is your solution.
