We analyzed 1,664 negative reviews to understand why users abandon the most popular Marketplace apps — and what they want instead.
Specific, exploitable gaps in the top Marketplace apps on the App Store.
Search algorithm completely broken, hiding seller inventory and destroying sales for long-time users
"I've been selling on Poshmark since 2015. It used to be such an amazing platform. This is where I do 95% of my business. I used to make SO much profit on this app. Sales have completely depleted within the last few years"
"I HAVE NOT MADE A SALE SINCE JULY2025! I've been on Poshmark for over 6 years. It used to be a good selling app until Jan. 2025."
Terrible seller support and unfair dispute handling that allows buyers to abuse return system
"the support team SUCKS for the sellers. I've messaged the support team FIVE different times about an issue and have been completely ignored 3 out of"
"I used to love this app, but the way disputes are handled is completely unacceptable. I received a final decision in my favor after a full review with photos and listing details. A day later the buyer opened another 'Item as not described' case"
No protection against inactive sellers and unhelpful support system that takes too long to respond
"they do not filter sellers correctly so you will get inactive sellers and it's up to you to find out if they are active or not. Mercari does very little to protect you from inactive sellers"
"Mercari health center and support system needs a lot of work their employees don't know what they're doing. They take super long to review help request."
Arbitrary permanent bans with no recourse and failure to enforce their own authenticity guarantees
"This afternoon I got an email from eBay stating that my account was permanently suspended, 'because of recent accounts activity that had raised security concerns.' So I contacted an assistant to see why my account was suspended and what I did to get"
"when attempting to have eBay resolve the issue and adhere to THEIR OWN guarantee (Authenticity Guarantee) they're nowhere to be found. I've tried mu"
Excessive spam/ads and privacy concerns with tracking user data even after paying to remove ads
"The free version has an obscene number of spammy ads. More on that later. If you pay to remove the ads, their terms state they still track & sell all your web activity"
"very hard to report people and click on something that you're not interested once and they'll keep sending you notifications about it until you delete the entire app"
Sellers frustrated by rising platform fees (seller fees + shipping costs increasing while sales decline). Buyers note inflated prices compared to alternatives like Amazon. Fee structures unclear and changing frequently without warning.
Sellers express willingness to pay for features that actually drive sales (better search visibility, analytics, promotion tools) rather than cosmetic updates. Current pain is paying high fees while getting worse service and fewer sales.
