Is this mobile app listing legit? 7 red flags to check first

Short answer: you cannot prove a listing is legit from the listing alone, but you can tell quickly whether its numbers hold together. For a mobile app, check the 7 rules below first, send the seller the matching questions, and only then pay for verification. The free checker runs all 33 rules on pasted listing text in about a minute.

What usually goes wrong with a mobile app listing?

Mobile apps depend on the App Store and Google Play, on paid installs, and often on a short history. Ask how users are acquired and what it costs.

"Legit" means two different things. A listing can be honest and still a bad deal, or polished and still untrue. The rules below test the first part: whether the published numbers agree with each other and with comparable listings. Only access to the seller's accounts (read-only Stripe, analytics, Search Console, the platform dashboard) can test whether they are true.

The 7 checks that matter most, with the question to send

Rule	Severity	Ask the seller
Platform dependence	MED	What do the platform's terms say about transferring the account, and has it ever been suspended or warned?
One channel above 60%	MED	What happens to revenue if the main traffic channel halves? Has it ever?
Under 6 months old	HIGH	Can you show every month since launch, with where new customers or readers came from?
Under 12 months old	MED	Can you show monthly revenue and profit since launch, with the main source of new customers each month?
No churn figure	MED	What were monthly customer churn and revenue churn for each of the last 12 months?
No connected data source	MED	Can you connect the revenue and analytics accounts read-only, or screen-share them live?
Multiple above the typical range	MED	What justifies a multiple above comparable listings: growth, contracts, or something not in the listing?

Rule names and severities come from our published 33-rule set (rules.json). The questions are our suggested wording.

Is the asking price in a normal range?

Our October 2026 sample had too few listings of this type to publish a type-specific figure (we publish only groups of 8 or more). Across all 36 listings priced $10k–$150k, the median ask was 26.8 months of stated profit (2.23× annual profit), and 36% of listings that stated an age were under 12 months old. Asking prices, not sale prices (data and method).

How do you check it in 10 minutes?

Paste the listing into the free checker and note payback and every flag.
Send the seller the questions for each flag raised. A seller who answers clearly and offers read-only access is a good sign; one who avoids the question is a flag in itself.
Compare the answers with what the listing claimed, then decide whether this listing deserves paid verification.

FAQ

Can a free checker tell me if a mobile app listing is a scam?

No. It tells you whether the published numbers are consistent and complete. Fraud is ruled out only by checking the seller's accounts directly, ideally on a live screen share or with read-only access.

Which red flag matters most for a mobile app?

The high-severity ones in the table, when they appear: they mean a number is missing or contradicts another. After those, the type-specific risks above (platform dependence first).

Should I pay for due diligence on this listing?

Only once it survives the free checks and the seller's answers. A $79 first-pass memo (free to request, paid after delivery) ranks every flag against your own limits; human reviews cost more and work from seller documents.
