4. Lookout (iOS)
If you’re looking for the ONLY all-in-one security application for your iPhone, then Lookout! is where it’s at! Lookout! is an application that helps you find your iPhone in the unfortunate case that it’s stolen. However, the application is so much more than that. For starters, the application auto-saves your last location and periodically backs up contacts. This way, you never have to worry about losing phone numbers and always have a running log of where your phone is. The app is linked with its own website, so you can access it from your computer or another device at any time.
