This practical software has only one purpose: keep away mosquitoes. When activated it causes your iPhone or iPod Touch to send out a frequency between 7,000 and 9,000 Hz capable of keeping away gravid female mosquitoes (that is those biting). Ideal for outdoor use, during a dinner or an evening walk, also usable at home. This frequency can be heard by both human ears and pet ears, so that we suggest to set volume at an indispensable minimum level, particularly whether you are in a close place. Obviously it must not be listen to directly on the earphones.
