Don't Leave It! vs PullApprove

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.
