### 2/5 — Used to love it

*2025-02-28, version 3.2.1*

This was my fav app to annoy my young neighbors in the morning after they’d been loud all night. Now I can hear the human repell? Not trying to repell myself too.

### 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!!

### 2/5 — Не работает

*2023-08-09*

Попробовала на своей собаке ноль эмоций, даже ухом не пошевелила

### 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
