Not vey loud. It states "loud in silent mode" but there is no menu or setting to go to, to increase it. Waste of my time!
Good to have it
I luv it This is so grate to have it saved me from being kid naped. Also perfict for scarin the crap out of every one!!
S.O.S. Whistle I wanted a whistle in case of trouble while out alone, or if separated from others during hiking trails. This will be excellent!
Perfect For Emergencies Anyone who downloads this app, don't make the mistake of leaving your earphones on.
Does what it says But no more. Other whistle apps have much more options, different types of whistles, SOS signals and take far less storage space to boot.
Review upon request, increased the output of the whistle sound.
