The mosquito repel feature . It has been scientifically tested that 20,000 hz ultrasonic frequency does not repel mosquitoes 😠so No, ultrasonic devices emitting sounds at or above 20,000 Hz do not repel mosquitoes; scientific evidence and numerous studies, including a systematic review by the Cochrane Collaboration and field studies by the EPA and universities, show these devices are ineffective at preventing bites. The idea that high-frequency sounds deter mosquitoes is a persistent myth, and some research suggests effective mosquito sounds are at much lower frequencies, around 150-500 Hz, which is in the audible range for humans, not the ultrasonic range
So I was at the sink washing up and my phone fell into the water but it was still working just the audio was not, I went straight to this app hoping the water removal button would work and thankfully it did, just make sure you take off your phone case and turn your volume all the way up, thank you to the people who made this app❤️❤️
Could be better like saving your favourite frequencies, but no
Using a compact screen - can only see bottom tips of frequency numbers that are above the top of the screen. ‘Subscription’ fee seems extortionate
Not too bad!!!!!!!!!!!
Options on how you dial to the desired number would be helpful. The speed at swiping up and down is really fast. A keypad to type in number and also being able to save numbers used frequently would also be useful 👍
Great app. Would be good to add favourite frequencies. I use it for noise generation and wall attenuation testing with a huge Bluetooth speaker.
Too hard to adjust
Happy so far
The app was simply a dream to use because it seemed know what I was thinking… outstanding.
