DoorMind — Smart Door Sound Monitor
Never wonder "Did I lock the door?" again. DoorMind turns your iPhone into an always-on door sound detector — quietly listening in the background
so you don't have to think about it.
How It Works
DoorMind uses your iPhone's microphone to detect door sounds in real time. The moment it hears a match, you get an instant notification — even when your screen is locked or the
app is running in the background.
Teach It Your Door
Every door sounds different. That's why DoorMind lets you record your own door sounds as templates. Record 3–5 samples for the best accuracy, and DoorMind will learn to recognize
your specific door — not just any door.
Perfect For
• Reminding yourself to lock the door before you leave
• Getting alerted when someone arrives home
• Making sure you haven't left your phone behind
• Monitoring a door in another room without being there
Key Features
• Real-time door sound detection with instant notifications
• Background monitoring — works even on the lock screen
• Custom sound recording for personalized accuracy
• Live sound level meter so you know it's always listening
• Recent events log to review past detections
• 100% on-device processing — your audio never leaves your iPhone
Privacy First
All audio processing happens entirely on your device. DoorMind never records, stores, or transmits your audio to any server. What happens in your home, stays in your home.
