## Cosduck Reviews in United States

### *---- "x"
whenever i try to apply i get an 'error:regionnotallowed'
-- Kabaws, 2025-06-15

### ***** "Really good app"
I love this app, love all the products and the campaigns.
-- Loopyyy, 2025-06-05

### ***** "Great app!"
UPDATE: they support team finally got back to me via email and fixed my problem. The app works and is great! Every creator who specialize in kbeauty/ Asian beauty should run to install it😤😤.

I was emailed about cosduck, and later when other creators said good things about it, I installed it. I would love to use the app, but it literally does not let me apply to ANY campaigns at all, even the ones that JUST opened. I would go through the first two checks and the last “apply” button, it would show an error saying “permission denied” every time. I’ve emailed, reported issue, and DMed them, to no response - this and 2 scheduled emails are my last resort :((

### ***** "Genuine Review"
I’m not sure why the other review didn’t like this app but I was emailed by a cosduck pr manager and I was skeptical at first but to gain my trust, they sent me the money first to buy the product. After that, I started using my own money to buy the products, and they have sent me my money back after I finished my video. This app is really good for smaller influencers like me, I don’t have a large fanbase but I enjoy reviewing their products 🤍 If you are worried this review is fake, you can message me on Tiktok @odettefleurs for confirmation! I love this app, def recommend

### **--- "Products Great but Customer Service and App Unreliable"
I’ve loved getting to sample various K-beauty products in exchange for a review. My refunds are usually timely. However, there have been a few times that the app has glitched and I have not been able to complete a campaign. Additionally, two of the products I requested by shipping were sent several weeks late and one never arrived. Finally, I updated my password but have still had issues logging in on another decide. Each time I email Cosduck about these issues, I do not hear back for several days or weeks, if at all. This has resulted in an inability to complete campaigns in a timely manner due to glitching or delays, which then restricts me from participating in new campaigns for several days and receiving my refund. My hope is that in writing this review, I will finally hear back from the Cosduck team.

### *---- "."
I can’t even enter my TikTok account, when I do it and go into the app, it has not updated and still asks for it.
-- skibidi boilet, 2025-05-14

### *---- "WHAT. IS. THIS. APP."
Bro I stg I had to delete and redownload every single time I have to get in this app because it signs me out of my account and won’t let me back in unless I delete and restart. I have a video due tonight and I need to submit it but now I can’t.
-- soiree .e, 2025-05-08

### *---- "Make it less glitchy!"
I loved doing campaigns on cosduck! However, these days my app is super glitchy and when I try to apply for a campaign, it lets me check the circle on the first 2 steps, but then the screen goes blank and only says next on the bottom. 
Then, it started asking me to log in. I would Put in my correct user and password. Then, it would show the buffering sign and not actually log me in. 
It’s so frustrating! I really enjoy doing these campaigns🙌.  
Please fix this 🥲🥲so I can do more campaigns.
-- SHAME IS THE GAME, 2025-05-04

### **--- "Bad"
I don’t like this app because it literally kicked me out and I can’t go back in my account for some reason and this app has access to my tik tok so im worried about what’s going to happen to my tt account
-- JENEHEEJJEJEJJEJSUUDUDUYDYDF, 2025-05-02

### **--- "constant bugs, no one responds"
I loved this at first but now my account is restricted due to “late” posts, the problem the products never shipped, therefore I cannot make a video on a product I haven’t received. Now I’m restricted from applying for more campaigns and locked out of my account. I have sent so many emails and no one ever responds.
