Don't Leave It! vs Noted

Don’t Leave It! is the patent pending reminder app, so you don’t leave your location without bringing your personal items with you.

Don't Leave It! is a free proximity-based reminder app that creates an invisible perimeter around your stuff. When you cross that perimeter, the app reminds you to take whatever item you've chosen. The user experience is simple and useful: Just pick an item you don’t want to leave without (e.g. purse or jacket or backpack, etc.), set how far you can walk away before getting an alert (e.g. 60 steps), and Don’t Leave It! will remind you to bring your item when you walk away.

Noted is a social music discovery app that helps you find music you like from people you know.

Noted is a social stream of good music chosen by friends that learns as you engage.

Noted combines multiple music-libraries, friends and a “special sauce” that learns your musical taste as you interact to allow you to discover new music from your friends and share your favorite songs with your followers.
