Mosquito Shield Watch

Too many mosquitoes? Try this sound-based deterrent on your Apple Watch. This app emits specific high-frequency sounds designed to disturb mosquitoes, especially fertilized females (the ones responsible for bites). Two sound modes included: 22 kHz Mode (ultrasound) Inaudible to humans. Frequently used in so-called mosquito repellent devices. May disturb some mosquito species. ~700 Hz Mode (audible buzz) Mimics the sound of a male mosquito. Studies suggest this can repel fertilized females, which generally avoid males after mating. Fun fact: around 80–95% of female mosquitoes in any given area are already fertilized. The male-like buzz may discourage their approach. Great for camping, evenings out, travel, or summer nights outdoors. No ads, no in-app purchases. Important disclaimer: This app is not a scientifically proven mosquito repellent. It emits two sound types that may disturb some mosquitoes, but no guaranteed effect is provided. Scientific consensus on sound-based mosquito repellents remains inconclusive.
