Smartphones are already capable of capturing great photos and video. What should you do about the sound though? The Sennheiser Memory Mic is a wearable omnidirectional condenser microphone that connects to your iPhone via Bluetooth and records/stores up to 4 hours of audio.
This microphone comes with a magnetic clip, so you can wear it easily.
