Now I can hear the human repell? Not trying to repell myself too. ### 2/5 — Не работает *2023-08-09* Попробовала на своей собаке ноль эмоций, даже ухом не пошевелила ### 4/5 — От грызунов *2022-11-26* Работает!! Включаю с перерывами на несколько дней ### 2/5 — Dubious *2022-09-16, version 2.0* I am sitting right next to my dog with range at the highest setting, and he had no reaction at all. That doesn’t instill confidence this would work on rodents or insects, but how could you ever tell for sure? ### 3/5 — Как так *2022-07-11* Запустил приложение, жена ушла к другому. Бляха-муха! ### 3/5 — The first time I turned it on the rats ran second time and third time they seem undeterred *2022-01-20, version 2.0* Well I didn’t record first name is unbelievable I didn’t think this thing will never work and it unreal second night seem like it worth it they did work actually it was started getting really cold and they went there getting in the attic above our room and they took off I remember it ran they ran out of the attic that night so have a great today same undeterred as much but I shut up now so I will put another review in here tomorrow to let you know if I get another came home pretty late in literally two or three ran between my legs and they’re pretty big rats for like 1 to 1 to 4 pounds the big mom and dad were on top of the fridge raider with the babies about a half a pound each and we’re about 100 of them I swear it was insane and it freaked me out so bad I couldn’t sleep all night but once I turned on theThey seem to stop making noise Elise and kind of disappeared in the one above my bedroom took off and I could hear them run out of the attic so still good news I will let you know tomorrow how it goes thank you so far unbelievable that one guy second to last one and he was horrible he’s an idiot ### 4/5 — What..? *2021-10-15, version 2.0* So the app seems good, I like how it has several options, and it even gives a range meter, but, at the far right, there is a “Humans” option. Why? ### 2/5 — Не понятно( *2021-05-05* Не понял, работает или нет!!! Очень плохо что отключается постоянно! В использовании получается полный ноль! Или бди!!! А когда я бдю, то и сам могу Комаров щёлкать!!! ### 1/5 — Recover Windy app *2021-03-27, version 2.0* I purchased Windy app 0.99$ but today it didn't work. I love Windy more than others about windy because it combine compass and windy. I request developer recover it for me, please! Thank you so much! ### 1/5 — Does not work. *2021-01-22, version 2.0* I tried this app multiple times on rats when rats crawling through my room walls or when rats roaming around the kitchen to the living room and it doesn’t do the effect to any rodents at all. Plus, switching to canine sound is very horrible! Your ears will hurt so bad as the whistle for dogs. What’s worst is the the human alert sound is bad as the canine sounds but worser! The human alert sound will hurt your ears so bad and not just your ears will hurt, it’ll effect yourself getting a headache. I would give this a zero star. Everything thing on this app does not work. It’s a fail. ### 1/5 — Not good *2020-10-10, version 2.0* Bad and very very bad ### 1/5 — Does not work on squirrels *2020-10-10, version 2.0* I downloaded this because the review says it works on rodents. Well, squirrels are rodents. They sit up in my pines and eat green pine cones leaving a mess all over my cars and driveway. Anyhow, it doesn’t work. Totally useless for squirrels anyway. I’ll test it on our Florida mosquitoes this evening. If that doesn’t work, it won’t be wasting any more room on my phone. If it does work, I’ll up the stars. Ok, here’s my update after testing this thing on Florida mosquitoes...IT DOES NOT WORK! Totally a toy. Don’t download if you need the space on your phone. Honestly, it’s a joke. The reviews with anything other than 1 star are probably the developers or paid reviewers. Don’t waste your time on this. ## Most critical reviews (10 lowest-rated) ### 1/5 — Doesn’t work *2024-10-02, version 3.2* Simply doesn’t work ### 1/5 — Куль *2024-07-28* После того как включил, пришли тараканы человек 100 и попросили меня поставить лайк этому приложению, значит работает. ### 1/5 — Doesn’t Work *2024-02-17, version 2.0* Saw a mouse run under a mobile cabinet in my kitchen. Heard it eating on something. I started the Repeller on rodent setting and put my phone on the floor next to the cabinet. The mouse continued doing what was doing without noticing the sound. ### 1/5 — Funktioniert nicht *2023-09-15* Meine Hunde interessiert es nicht. Die reagieren nicht einmal ### 1/5 — Надежды нет *2023-08-25* Не работает, комары сожрали😅 ### 1/5 — не работает *2023-08-17* Пробовала все функции, муха спокойно сидела на динамике, а убежала я. Сижу с головокружением и тошнотой. Похоже приложение разработали насекомые, чтобы избавиться от надоедливых людей, никак иначе. Всем от души желаю навсегда избавиться от насекомых!! ### 1/5 — 🚫 *2022-08-12* doesn’t work ### 1/5 — Не работает *2022-06-20* Не работает ### 1/5 — Комар летает возле телефона при включенном ультразвуке на радиусе 6 м *2022-05-30* Комар летает возле экрана телефона при включенном ультразвуке на радиусе 6 м. ### 1/5 — Приложение ни о чем! *2022-05-18* Что за бред? Что за приложение? Во первых оно не работает в фоновом режиме,после блокировки экрана приложение просто самозакрывается! Во вторых ни каких Комаров оно вообще не отпугивает ни сколько,не тратьте зря время на это псевдоприложение! ## Most praised reviews (10 highest-rated) ### 5/5 — Отличное предложение *2023-08-04* Работает просто восхитительно, за отзыв мне никто не платил(для мамкиных хейтеров) . На счет тараканов , мышей и прочих не могу сказать. Но на комаров работает просто великолепно, возможно это также зависит от размера динамиков на телефоне. В любом случае скачивайте и наслаждайтесь, лучше чем любые опрыскиватели от комаров. ### 5/5 — Perfect classroom prank *2023-03-22, version 2.0* Only teenagers can hear this so you can’t get in trouble and you can annoy everyone ### 5/5 — 🙏 *2022-10-25* приложение прикольное, вроде как даже работает. Комары, кусавшие пол ночи и жужжащие над ухом пропали после активирования приложения. Наконец смогли спокойно уснуть. ### 5/5 — Good *2022-04-25, version 2.0* Good ### 5/5 — It worked! *2022-04-01, version 2.0* A rat was in my apartment walls driving me and my neighbors nuts. Haven’t heard anything since I downloaded the app. Also, FYI the human one works on people under 35. I couldn’t hear anything but my younger sister could 😂 ### 5/5 — Very great but needs more *2021-04-02, version 2.0* Please add cat repeller mode too ### 5/5 — Well they listen *2020-11-10, version 2.0* I wanted this for rats and mice Switch it on and the scrabbling stops so they can hear it and my cats don’t seem to I guess it needs to be on continually for it to have a lasting effect, but if they are annoyed enough regularly they may just leave ! I’ll be buying a plug in system now I know the idea works ! ### 5/5 — Useful *2020-05-20, version 2.0* Been using this app now for the past 24 hours now and I haven’t been hearing scratching in my ceiling since I downloaded it. Before I got it, I would hear something scratching in the ceiling and what worries me is the fact that squirrels and other rodents chew through anything they can get their mouth around. Thanks to this app, I bought more time for my mom to call in an animal removal service. I’ll keep you posted on the performance of the app as I continue to use it. ### 5/5 — Cool *2020-04-19* Très bonne Applicassions j’ai essayé parce que il y avait plein de cafards chez moi et en à peine un jour ils j’avais disparu je la conseille partout et ça devrait rester dans l’App Store ### 5/5 — Unbelievable *2019-06-05, version 2.0* The first ultrasonic insect repeller on iOS that actually works so far it works on flies ants mosquitoes even the dog heard it. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
