“I plan to use mine to record long distance phone interviews. There are often really interesting moments in conversation that would be lost with conventional note taking. With RECAP, I can capture those moments, no matter where I happen to be.”

How It Works

RECAP S2 sits between your phone and your headset. It captures both sides of the conversation and sends the audio to any recording device — a computer, digital voice recorder, or even another phone.
  1. Connect — Plug RECAP into your phone’s headphone jack (or use a Lightning/USB-C adapter)
  2. Plug in your headset — Talk normally through RECAP’s headset port
  3. Record — Connect the RECORD port to your computer, voice recorder, or mixer
That’s it. No batteries, no Bluetooth pairing, no apps to install. RECAP works the moment you plug it in.

Why Hardware Instead of an App?

Phone manufacturers have made it increasingly difficult for apps to record calls. Apple blocks it entirely on iPhone. Android has restricted call recording access in recent OS updates. Even apps that still work often capture only one side of the conversation, or require cloud processing.RECAP bypasses all of that. It captures the analog audio signal directly — both sides, every time, on every phone. No OS restrictions, no app permissions, no cloud dependency.
