SlothCam is the only iOS webcam app which supports both iCloud syncing and AppleTV/Airplay (iOS5 only). SlothCam is a fully customizable webcam browser for all iOS devices. This app was inspired by my popular Mac OS Dashboard Widget and allows you to view multiple live webcam feeds on your iPhone, iPad or iPod touch. Simply add your webcam URLs to the app, and swipe left and right to change views, just like the Apple photos app. SlothCam has a clean simple interface that allows you to view your webcams full screen. SlothCam comes with a few built in sample webcams, but the purpose of this app is for you to add your own. There is no limit to the number of cams you can add, and this app can be personalized for many possible uses. For example, you can use it to monitor local traffic conditions, check on the weather in your home town, keep an eye on surf conditions, etc. Any webcam which has a JPEG image stream is supported. You can also use SlothCam to monitor any image file on the web which is periodically updated such as satellite images, weather data, etc. SlothCam works on all Apple iOS devices. Buy one copy of SlothCam and run it on your iPhone, iPad, and iPod Touch! You can even export the settings from one of your devices and import them on the others. With SlothCam you can: •Save any webcam image directly to your device's photo album. •Save a series of webcam images. •Import and export webcam lists using email. •Migrate your settings from the Dashboard widget to the iOS app. •Enter webcam lists on your Mac or PC via a webpage and send them to the iOS app. •View your list of webcams as a slideshow. •Sync webcams between devices using iCloud syncing. •View your webcams on an external monitor or TV using AppleTV and Airplay.
