Windows: With camera remote control tools, you can take awesome photos, including self-portraits and time-lapse photos. DigiCamControl gives you access to almost all camera controls from your Windows PC or through a web browser. It currently works with most Nikon DSLRs and has experimental support for Canon cameras.
Android: Most phone recovery apps require you to install the app before you lose the phone. Android Lost, however, can be remotely installed, and it comes with a slew of useful features beyond just locating your phone.

Android: AirDroid already controls your phone from any web browser, but the latest version of the app offers more useful features, like a new “find my phone” service that pinpoints your device via GPS, and complete remote control of your device’s camera. Plus, it no longer requires your phone be on the same network to connect to it.
