Every time you want to use the device you have to delete the app and redownload it just to get it to connect at all. Then, once you do have it connected it keeps disconnecting itself every 5-10 seconds and you have to fully restart the device every time. There’s a very specific order you have to turn everything on or it won’t work. And there’s no indication of that anywhere, you just have to trial and error until you get it (open app, turn on device, turn on WiFi, go back to app, connect the camera) absolutely garbage. I hate this device so much. ### 1/5 — 断连，闪退 *2026-05-25* 好好的一个产品，做出这么垃圾软件，用脚写的吗？ ### 1/5 — Camera Image Terrible! *2026-05-18, version 4.5* The image of the camera to the app is horrendous! It doesn’t auto focus. ### 1/5 — 失望 *2026-05-17* 连接上设备一片雪白，里面的灯光开关也是摆设，国产软件就这？ ### 1/5 — Not connecting *2026-04-01, version 4.5* I did EVERYTHING the app said to do. Would not connect to my iPhone. So the item was useless ### 1/5 — 有bug快来修！ *2026-01-28* 连上WIFI但显示未连接设备 ### 1/5 — 垃圾 *2026-01-08* 垃圾 ### 1/5 — 用不了 *2025-12-13* 连上了就是不显示已连接，就是用不了 ### 1/5 — 卡 *2025-12-09* 我是不明白这种连接方式能卡？ ### 1/5 — Non parte la telecamera *2025-11-18, version 4.4* Non parte la visione sull’app nonostante sia collegato il Wi-Fi ## Most praised reviews (10 highest-rated) ### 5/5 — MUST GET THIS APP *2026-03-30, version 4.5* Very helpful gives you free Wi-Fi when u need it MUST TRYYY ### 5/5 — Très bonne application *2025-01-30, version 4.3* efficace avec la connexion par wifi, facile d’utilisation avec pour l’aspirateur à point noirs ### 5/5 — Ear camera works great! *2024-12-28* Easy to set up and super clear image. Great deal ### 5/5 — I Looked on Tik Tok, YouTube and here!!! *2024-12-27, version 4.3* Step 1. Download the app by scanning the instructions booklet. Step 2. Charge the device it will not connect without being charged. (Trust me this was the issue I had.) Step 3. Click the button at the bottom on the devices to turn it on.( it will blank with a blue light until you connect it to wifi Step 4. Go to settings on your phone Step 5. connect the Wi-Fi click on whatever says cooleer it should have a few numbers beside it as well Step 6. Give the app permission with a pop up notification read it carefully so you do it correctly Step 7. When you open the cooleer app up again it should switch from saying Wi-Fi not connected to Wi-Fi connected Step 8. Click power button it should turn green Step 9. You’re all set I definitely had to do this about 10 times I almost said forget but patience is a virtue lol Hope this helps don’t send it back it just take a little minute to get connected🫶🏽🫶🏽 ### 5/5 — Top *2024-09-25, version 4.2* Connecté très rapidement sur IOS, la qualité de la caméra est top. ### 5/5 — Works great *2024-08-27* For the people have problems connecting… u have to connect the scope as a wifi connection in settings then press the power button within the app. Hopefully this will help. ### 5/5 — Très bien *2024-05-13, version 3.8* Connecté sur IOS en 30 secondes ! L’image caméra est top, c’est bizarre au début… faut que j’essaie tous les outils pour un avis à l’usure mais pour le moment mais oreilles sont très propres 😊 Bon achat. ### 5/5 — 使いやすい‼️‼️‼️‼️❣️ *2024-04-13, version 3.7* とても使いやすくて気持ちがいいです ### 5/5 — Connect with no issue here’s how I did it *2024-03-24* 1 Turn on the camera 2 open the app 3 minimize the app and open your WiFi settings 4 connect to the WiFi named after your device 5 go back to the app 6 Click to initialize your device 7 use your device Simple and works great takes some practice to get the hang of using it but I like it so far And like I showed above connecting is simple with no password required just like they said ### 5/5 — Works great, a little confusing to set up *2024-03-17* At first, I was like most people here who were having trouble connecting it to the app, but after watching a TikTok tutorial, I found out you have to look for “Cooleer” under WiFi/networks on your device, not Bluetooth like I assumed. After I did that, it connected just fine! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
