Teenager Repellent: Ultrasound
This technique is already used by police and local authorities worldwide to fight off loitering youth. Teenager Repellent offers the same technique now for your mobile phone, and because of the portability you can even use it on the road, trains, subways, or at the park.
Turning on the high frequencies sounds will make the area around you unattractive to teens without causing discomfort to adults. The sound of the app can almost exclusively be heard by young people till around 25 years.
HOW TO USE:The app has six different high frequencies: 14 , 15 , 15 , 16 , 17 , 18 , 20 KHZ . Depending on your age and the condition of your hearing it's possible that you can still hear some frequencies. Only turn on the frequencies that you can not hear.
RANGE:The effective range is dependent on your phone's speakers. Tip: Connect your phone to external speakers for more range.
Teenager repellent is a free anti loitering technique. Use is at your own risk.
--------------------------------------
SAFE:Research in the UK, Netherlands , Germany and Belgium have shown that no hearing damage is caused with normal exposure to high frequency (ultrasonic) sounds.
MEDIA:An estimate of more than 3500 councils, shop owners and police in the USA are currently fighting loitering youth with high frequency (ultrasonic) devices, also know as mosquito boxes. The technique has also has won the Innovation Prize Police ( PIP ) in 2006.

Everytime I try to use it the pop up ads get in the way and take to their site. It is so frustrating. I understand you need as but not every .5 second, as I try to turn it on. Also a button that allows all to switched on/off at once would be nice.
Four stars because the amount of ads you burden the user with TAKES AWAY from the experience and actually interferes with the abillity to use the app itself! I was going to rate the app less than what i did because the ads are that annoying however this is the only app in here of its kind i could find so i gave it a 4! Its ridiculousness for that many ads! Lay off a little and people might actually use it more thus increase your revenue for being user friendly!
So many ads popping up the app was useless. Didn't appear to work but was so annoyed by the ads everytime I tried to figure it out. Uninstalled after 3 min and 10 adds
Too many pop up ads while I'm using the app. Before and after would be fine but these are too intrusive. Uninstalled 5 minutes after first installation.
So far it seems to work. I can only hear the lowest frequency wich is perfect. Will be trying it later with some annoying kids.
Liked the really loud music advert I was spammed with after a minute. Nothing is ever good enough for me, especially this poor excuse of a calculator.
No way to know it is working if you are an old fart unless you test it on unsuspecting youth. Perhaps add an audible beep for old farts so they know when the sound has started. To all those saying you can't hear it I suspect it is because you is an old fart!
invasive adds ruin the experence Create a situation where there is no discretion when you go to use the app because a advertisement can come on over your speaker and front you off how ridiculous to do this to a really good app I would be happy to pay to get rid of those ads and are now looking for a new app with similar kind it is not broken this way thank you for trying but these new advertisements make the app useless to me personally
Too many ads The frequency in which the ads come up in this app pretty-much render it almost unusable.
Tooooooo many nagging pop-up ads. A few here and there I can accept, but you're taking the p!ss. Uninstalling.
Ridiculous number of ads. Whether it works or not is immaterial, you can't use it because it's always trying to sell you something. I appreciate it's a free app, but it's ridiculous
Ads. I mean ADS!!! if you press one frequency ..AD!.. Unclick that frequency ..AD!.. Click another frequency Aaaaaaaand you know what's coming...AD!!!... I mean ..AD!.. It's ..AD.. annoying. ..AD!..
Does what it promises BUT alongside very annoying continually interrupting adverts. Pick another app.
Does the noise but the ads are intrusive, and verging on trying to trick the user to install suspicious software.
Would be a goog app if the ads didnt get in the way. Not useable with the ads.
It works but... the adds are way over done to the point that it damages usefulness.
Usefull informative outstanding.commendable hubriis.Next generation software .Completely off the scale .Dynomite!.Graphics are 1st grade material.
Way too many ads. Practically unusable due to the ads.
Ads pop-up everytime you touch the screen. Pain in the @ss!
Doesn't exactly make you inconspicuous to the people you want to deter with the crazy ads blasting out!
Not sure about deterring kids but kept my cat entertained trying to find the 'mouse' 🤷♀️
Nice and helpful app, accept for all the unnecessary popup ads.
The app may work, but the ads are really annoying
Doesn't actually do anything other than display loads and loads of adverts
Too many ads popping up when playing with this
I think your app is meant to do good in certain cases. But when applied to my circumstance the loiter's know exactly how to turn your app off. You need to work this out, for they only laughed at it upon turning it off. May i also say you should give its user the choice to have it played in the background .....or not. One last suggestion. Seems high pictched frequency apps are not as kuel as they once were. Ultrasonic sounds or subsonic sound is all the rage now. Incorporate both.
