Anti Pest plays high-frequency tones often advertised as repellents for mosquitoes, rodents, and other pests. Here is a clear look at what to expect, how to use the app, and what the science actually says.

The honest answer: scientific evidence is mixed, and effectiveness varies by species and environment. Some users report a noticeable reduction in bites. Treat the app as a complement to other measures (screens, fans, repellents), not a guaranteed solution.
At normal phone volume, the tones are within the range a typical phone speaker can produce safely. Children and many pets (especially dogs and cats) can hear higher frequencies than most adults, so they may be more aware of the sound. If a pet looks distressed, lower the volume or turn the tone off.
At reasonable volume the risk is low. As with any audio, prolonged playback at very high volume close to the ear can be uncomfortable or harmful over time. Keep the device a few feet away and use moderate volume.
Hearing range narrows with age. Most adults stop hearing tones above 15-17 kHz, while teenagers and children can often hear up to 18-20 kHz. The "mosquito tone" presets are deliberately in that upper range.
Yes, but use the lowest volume that you find tolerable. Place the device on a table rather than next to your head, and consider setting a sleep timer.
Modern iPhone speakers can play tones into the upper kHz range, but output level falls off at the very top of the spectrum. The app picks frequencies that real-world iPhone speakers can reproduce reasonably well.
Outdoor performance is much weaker because sound disperses quickly and wind affects propagation. The app is best used in small to medium indoor spaces, like a bedroom or a porch with limited airflow.
Ultrasonic tones to deter mosquitoes and pests indoors. Chemical-free, runs on your iPhone.
Set up the app for sleep without keeping yourself awake.
If you have a pet that reacts to the sound, lower the volume or move the device to another room.
