Phone recording apps are unreliable. Apple blocks call recording on iPhone. Android has restricted it in recent updates. Even apps that still work often capture only one side, require cloud processing, or charge monthly fees.
RECAP S2 is a hardware adapter that bypasses all of that. It sits between your phone and your wired headset, capturing both sides of the conversation directly — no apps, no OS restrictions, no subscriptions.
Why a Phone Recording Device Beats Apps
Most people searching for a way to record calls hit the same wall: software can’t reliably do it anymore. Here’s why hardware is different:
- Works on every phone — iPhone (all models), Android (all models). No OS version restrictions.
- Captures both sides — Apps often only record your microphone. RECAP captures the full conversation from the audio signal.
- No monthly fees — Pay once ($99), use forever. No subscriptions, no cloud storage fees.
- Works with any calling app — Regular phone calls, WhatsApp, Signal, Zoom, FaceTime, Teams, Messenger — anything that plays through your headset.
- No announcements — iOS 18’s native recording plays a tone to the other party. RECAP does not. You are responsible for following recording laws in your jurisdiction.
- Works offline — No internet connection needed. Audio stays on your recording device, not in the cloud.
How It Works
RECAP is a passive analog device — no batteries, no Bluetooth, no software to install.
- Connect RECAP to your phone — Plug into the headphone jack (or use a Lightning/USB-C adapter for phones without one).
- Plug in your headset — Talk normally through RECAP’s headset port.
- Record — Connect the RECORD port to your computer, digital voice recorder, or mixer. Press record.
That’s it. RECAP works the moment you plug it in.

Frequently Asked Questions
Does RECAP work with the iPhone 16?
Yes. RECAP works with every iPhone model, including iPhone 16, 15, 14, 13, SE, and older. Phones without a headphone jack need a Lightning-to-3.5mm or USB-C-to-3.5mm adapter.
Can I record calls without the other person knowing?
RECAP does not produce any tones or alerts. Unlike iOS 18’s native recording, there is no announcement. You are responsible for following call recording laws in your jurisdiction.
What’s the difference between RECAP and a voice recorder app?
Voice recorder apps capture your microphone, which only picks up your side of the call (and often poorly). RECAP taps the audio signal directly, capturing both sides at full quality. It also works regardless of OS restrictions that block recording apps.
Does it work with WhatsApp and Zoom calls?
Yes. RECAP captures any audio that plays through your wired headset — regular phone calls, WhatsApp, Signal, Zoom, FaceTime, Messenger, Teams, and any other calling app.
Is there a monthly subscription?
No. RECAP is a one-time purchase ($99). There are no monthly fees, no cloud storage charges, and no premium tiers. Your recordings stay on your own devices.
How is this different from AI voice recorders like Plaud?
AI voice recorders like Plaud Note are standalone devices that sit near your phone’s speaker during calls. They record via proximity microphone, which means audio quality depends on speaker volume and background noise. RECAP connects directly to the audio signal for clean, consistent recording of both sides. RECAP also costs less ($99 vs $159+) and has no subscription requirement.
