Repurpose your iOS device into an intelligent edge-AI security monitor. Keep a private, silent guard over your hotel, Airbnb, or campsite and get real-time alerts anywhere.
Coming Soon to the App StoreAlertCatcher uses your device's microphone and camera combined with local machine learning models to detect anomalies and keep you informed.
Processed 100% on-device using Apple's SoundAnalysis framework. Instantly classifies footsteps, door locks, breaking glass, crying babies, or alarms.
Leave one device in your room in Guardian Mode. Carry your primary device in Receiver Mode to receive real-time push notifications of any detected events.
Uses low-overhead camera analysis to detect visual movement. On trigger, it captures a 30-second video evidence clip with a 60-second cooldown to save storage.
Dims the screen to 0% brightness and blacks out the UI. This saves battery and allows the app to operate continuously and discreetly in hotel rooms.
AlertCatcher is trained to classify specific categories of acoustic anomalies in real-time:
Locks jiggling, footsteps, doors opening, sliding glass doors, breaking glass.
Smoke/fire alarms, carbon monoxide detectors, human distress calls.
Running water, showers, sinks, and burst pipes.
Baby crying (perfect for portable baby monitoring), loud impacts.
Dog barking/howling, cat meowing. Monitor your pets when away.
We believe bedroom and hotel room monitoring must be private. That's why AlertCatcher processes all audio and camera frames locally on your device. Zero audio, video, or raw monitoring data is uploaded to the cloud—only lightweight text alerts are sent to your paired Receiver device when a sound or motion anomaly is classified.
