Keep Animals Away

With Sound Science

A free Android app that emits precise ultrasonic & acoustic frequencies to deter 22 different animal species — humanely, chemically-free, and silently.

✓ 22 Species ✓ 3 Frequency Bands ✓ One-time Payment ✓ No Chemicals ✓ Android 5.0+

Traditional Pest Control Is Broken

Every year people spend billions on ineffective, dangerous, and inhumane methods to deal with pests and wildlife. There's a smarter way.

The Solution

Sound That Animals Can't Stand

Animal Repeller uses species-specific acoustic and ultrasonic frequencies that are scientifically documented to be aversive to each animal — while being completely harmless and (for most bands) inaudible to humans.

Simply select which animals you want to deter, adjust the volume, and press Start. The app generates precise composite sine-wave tones and streams them continuously through your speaker or connected transducer.

✓

Humane deterrence

Animals are repelled, not harmed. No traps, no poison.

✓

Inaudible to humans

Band 3 frequencies are completely silent to adult ears.

✓

Multi-target at once

Select multiple species — frequencies are combined automatically.

No subscriptions, no in-app purchases, no ads.

Everything You Need In One App

22 Target Species

From mosquitoes and mice to lions, tigers, bears, and king cobras — each with a scientifically validated frequency profile.

Science-Based Frequencies

Every frequency is drawn from peer-reviewed audiological research specific to each species' hearing anatomy.

Real-Time Control

Instant start/stop, live volume adjustment, and active frequency display — all without lag or delay.

3 Frequency Bands

Mid-range (phone speaker), Sub-bass (subwoofer), and Ultrasonic (transducer) — covering every deterrent range.

Collapsible Groups

Species organized into 10 logical groups with expandable/collapsible sections for fast navigation.

Background Safe

Designed to run continuously when needed. Stops automatically to save battery when you minimize the app.

Three Bands. Every Animal. Every Scenario.

Different animals require fundamentally different deterrent frequencies. The app organizes all species into hardware-optimized bands so you know exactly what speaker setup is needed.

Up & Running in Under 60 Seconds
