How to Record Interviews on iPhone and Android

For journalists, researchers, podcasters and recruiters, a clean interview recording is the raw material everything else is built on. You need it to be reliable (no half-captured conversations), easy to transcribe, and — for sensitive subjects — private. Here's how to record interviews well on iPhone and Android.

What makes interview recording different

Interviews raise the stakes compared with casual recording:

  • You can't redo it. A dropped recording can mean losing the entire conversation.
  • Transcription is essential. You'll quote, reference and analyze it later.
  • Confidentiality matters. Sources and subjects expect their words handled carefully.

So the priorities are reliability, transcription, and privacy — in that order.

A reliable capture workflow

Using BlackBox:

  1. Test first. Record 30 seconds, play it back, confirm levels are good. Do this before every important interview.
  2. Tap Start recording, then set the phone on the table between you and your subject.
  3. Recording continues in the background, so a notification or app switch won't interrupt it.
  4. Afterward, find the session in the hourly timeline and play it back on the waveform.
  5. Tap Transcribe to generate text.
Reliability tip: On Android, set the app's battery usage to Unrestricted so long interviews aren't cut short. See the Android background recording guide. On iPhone, keep Low Power Mode off — details in the iPhone guide.

Transcribe without exposing your source

Uploading a confidential interview to a cloud transcription service may breach the trust — or the agreement — you have with your subject. BlackBox transcribes on-device, turning the conversation into time-stamped text without a single byte leaving your phone. That's a meaningful difference for journalism, HR, legal intake and research.

Protect the recording

  • On-device storage with no account keeps the file under your control.
  • Face ID / passcode lock on your library guards sensitive interviews.
  • Selective export means you choose exactly what to share and with whom.

Interviewees should always know they're being recorded. Beyond basic courtesy, many jurisdictions legally require consent, and ethical guidelines in journalism and research demand it. State clearly at the start that you're recording, and keep that on the tape. Our recording consent guide covers the legal landscape.

The bottom line

Great interview recording comes down to reliable background capture, on-device transcription, and tight privacy — plus always getting consent. Set your phone down, stay in the conversation, and let the recorder do its job. BlackBox handles capture and transcription on both iPhone and Android, entirely on your device.
