Field Recorder cannot record after upgrading to iOS7!
Most people will automatically tap "No" without even thinking about it.
When you try to record, you will experience no sound being recorded and the meter will show no activity.
To fix this, you have to give Hindenburg access to your mic in the privacy settings:
- Click the home button
- Find the "Settings" icon
- Scroll down to "Privacy" and tap it
- Scroll down to "Microphone" and tap it
- Scroll down to "Hindenburg" and turn the microphone on for the app.
