ShadowRecord

ShadowRecord is the ultimate "Time Machine" for your ears.

Have you ever zoned out during a meeting, only to realize someone just said something important? With ShadowRecord, you can press a button and capture the last minute of audio after it happened.
Designed for journalists, students, and professionals who value privacy and battery life.

✨ KEY FEATURES:

🎙️ Shadow Mode (Retroactive Recording)
Keep the app running in the background. It listens without saving, keeping a configurable buffer (up to 5 minutes) in memory. When you hear a "Eureka!" moment, tap save to capture the past audio instantly.

🧠 Smart Voice Activity Detection (VAD)
Don't fill your storage with silence. The intelligent VAD engine automatically detects when people are speaking and ignores door slams, typing clicks, and background hums. It only records when it matters.

Optimized for long sessions. ShadowRecord uses Android's latest low-power audio APIs and respects "Transient Audio Focus," meaning it won't interrupt your music until necessary.
