Slice to watch for packages and bargains

Jennifer Welsh, BI Science editor

App I can't live without: Slice

Why I love it: Slice scans your email for notifications and tracks packages as they make their way through ordering and sending and arriving.

It will say “arriving today” or “4 days away.” It’s not perfect but it's an awesome concept. It also tracks everything you’ve ever bought and lets you know if things are recalled or the price drops.

Free. iPhone/iOS and Android.
