Turn your iPhone into a cable release trigger with the Triggertrap Mobile Application. You need to buy a special dongle ($10), a dedicated cable ($10) and the mobile application for $10. You will spend about $30 on a medium grade shutter release cord, but this app has so many more features than what you might get with a medium grade option.
The Triggertrap features:
- Timelapse
- Eased timelapse (Tutorial)
- Sound sensor
- Shock & Vibration sensor
- Metal & magnetism sensor
- Facial recognition
- LE HDR (Tutorial & limitations)
- LE HDR Timelapse mode
- Distance-lapse mode (Tutorial)
- Motion detection mode
- Cable Release mode
- Star trail mode
