Ultrasound Barrier

I've tested the 5 targets except for 1 -- the rat, and I can say that none of which was affected. Therefore it is just a gimmick. Also, I could hear the sounds emitted for all targets and it does not annoy me even a bit. Very not recommended.

I could give it 2 stars because it is easy to use and intuitive but it simply doesn't work. It does not repelled flies nor mosquitoes. Annoying ads that make the experience of using this app even more frustrating. 1 star is good enough.

For several months I have rats running in the ceiling. Started using this app last week and I have been using this every night, I don't hear them anymore. An app that really works effectively! Kudos to the people who made this app possible!

It works, excellent. Thank you much. After I installed and then played the sound, without even 5 secs all the mosquitoes were all gone, perfect app in our area.

My phone speaker is heating up. I'm not sure if it's working, just afraid that my phone will break if I continue using. 😞 I really want to use it since there's an annoying rat on the terrace. But I think you need to test it on new phones and see how it's reacting on the phone itself.

I've been using the app for 1day & seems to be working well for the mosquitoes! it wud be the Perfect repellent app if it included an option for spiders! and you could use the buttons simultaneously & also worked in the background❗

I down loaded the Barrier APP only to find its all in written Chinese. However, we tested it with roaming flies at our table. Well, it was 120% effective with one fly standing still for 30 minutes lost. Thank you for your app.

This is a nice app but I uninstalled it after a few minutes. When I tried, it the rat under my bed ran but it really hurts my ears. I do not recommend to people with sensitive hearing. But at least the rat is not in my room anymore, I think it's in my sister's room by now😅

Believe it or not, I had trouble with mouse chewing the room ceiling wood every night, they go away after I use this app. Thank you

At first I was surely sceptical but I still try this apps. It doesn't work 100% but this apps do the job quite okay compare to other apps.

It takes five minutes to work, but after that it deters flies. Flies won't come around even with food out! I use it at outdoor restaurants and this app works very well on flies.

Well we were sitting here tipping a few beers and ya the flys were drinking as much as us turned the app on and BAM!! no flys to seal the deal we brought a pizza to the table ... and I put my life on this no flys . As o I had to write the review and turned app off and the flys were back u make the call . I do recommend this to anyone.

Literally had a mosquito land on my arm, I put the speaker next to it and it didn't move. Either no longer functional or mosquito mode doesn't work as advertised

Works, I actually got sleep after being fed on most of the night by mosquitoes. Now just to expand this app to be rid of jerks with bad pick up lines.

I was just targetting mosquitoes but it appeared all kinds of insects are affected too. I can hear them crawling away from my room. Very effective against mosquitoes. Trust me. Lots of love from the Philippines.

Yes, it's true... Nice Apps... Just connect to external speakers and you will hear the annoying Sounds...

This app is brilliant, at the moment I started it, the rat came out instantly and I was able to chase it out with no harm

It's ok I guess for what it is. I personally feel the name is a little misleading. I was looking for a barrier from ultrasonic noise harassment.

i can hear all the sounds it makes me headace ,is there anyone who can here the sound like me none of my family cannot hear the sound,i only heard ,its so anoying sound so thin and thick but this will peopably 100% work sure cos i can feel the sounds but makes he headache

Repels them perfectly!!! i used to get bitten by mosquitoes every day but now they dont come anywhere near me thanks to this app. Everyone should get this ready for summer!!

This app . . . . Add pop out while I click youngsters causing me panic snd suffering from headaches. Quite effective

Doesnt work . Played it right next to a mosquito an he was just chilling . Like his listening to a nice soundtrack . Rubbish app

trust me it works! just connect your phone to a speaker. if you just let the sound come from your phone it's useless

I turned on mosketo and could not hear anything then turned on youngster because of curiosity and i still hear ringing 🔔🔔🔔🔔🔔🔔🔔🔔📯

I uses it and I had flys nearly drinking my beer activated it works ... I love it works well for me then that's that used to bother me don't bother me no more okay

5 star . Only drawback is volume isn't loud enough...otherwise excellent !!
