This is an interesting download for iOS users – iMotion HD, a free time-lapse & stop-motion app for iOS.

Features:

• HD 720p capture and export
• Universal binaries iPhone / iPad / iPodTouch
• 4 capture modes (time-lapse, manual, wifi remoted*, microphone)
• Portrait and landscape orientations supported
• Useful capture tools (Onion skin, Grid, Manual Focus*, …)
• Video and photo exports: Photo Library, iTunes Sharing Folder and Email (in app upgrade)
• YouTube direct upload
• iMotion Gallery sharing
• Quick and smooth interface
• Autosave and direct preview
• Unlimited movie size
• Retina Display
• Multi-tasking

iMotion HD works with all iOS devices with camera:

• iPad 2,
• iPhone 4,
• Phone 3GS,
• iPhone 3G
• iPodtouch 4th generation

If that’s not cool enough for you, a free WiFi remote app, iMotion Remote, is also available that lets you preview and control iMotion HD.

Note: I hesitate to call this a free app because one of the most important features, exporting, is a $1.99 paid in-app upgrade.  🙁
