A second opinion before you pay

Second-hand apps make buying fast. That's great, until it's a scam, a price that's too high, or a purchase your budget didn't need. This site slows you down for one minute and gives you a calm verdict.

From listing to verdict

1
You show the listing
Paste the link, add screenshots, or type the details. Seller info comes from a screenshot of their profile.
2
Fixed rules check the item
Price against market value, condition, seller age and reviews, and classic scam patterns.
3
You describe your situation
Tight month or comfortable, impulse or planned, to use or to resell. How often you'll really use it.
4
Mamie gives her opinion
Our AI reviewer reads the same facts and adjusts the score a little, up or down, with pros, cons and advice.
5
You get a verdict
A score out of 100 and a plain answer, from STRONG BUY to POSSIBLE SCAM.

Rules first, Mamie second

Transparent rules
The score is a fixed calculation. The same listing and answers always give the same rules score.
A small nudge
Mamie can move the score by at most 10 points. She advises; she doesn't decide.
Scams stay scams
When the rules see a scam pattern, the score is capped at 29, and Mamie can't lift it out.

What it isn't

Not financial advice: a second opinion, you decide.
Not affiliated with Vinted, eBay or leboncoin.
Not a guarantee: a clean score doesn't prove a seller is honest.
