Availability
Downloads depend on your Apple Account storefront. The app is listed in 172 countries or regions, but it is not currently available on the China mainland App Store, so mainland China accounts cannot download it.
How it relates to the case studies
The case pages are method demonstrations: one real Amazon US category written out in full — demand, competition, cost, compliance and the unknowns — free to read and cite. The app is the self-serve version of the same decision card: you photograph your own product and it returns the same kind of judgment. The walking pad review is the worked example of the method the app runs.
FAQ
Is Ryndix: FBA Product Verdict free?
The download is free. Scanning uses consumable scan credits bought through Apple in-app purchase (1 Product Scan and 5 Product Scans). There is no subscription and nothing renews automatically.
Which devices and iOS versions run the app?
iOS 17.0 or later, on iPhone, iPad and iPod touch. The interface is available in English and Simplified Chinese.
What does one scan return?
One GO, OBSERVE or NO-GO decision card for the product you photographed. Measured signals, stated assumptions and missing evidence are labelled separately, so an input that could not be measured is shown as a gap rather than filled in with a plausible-looking number.
Is Ryndix Scan a different app?
No. Ryndix Scan is the short name for the same app. The App Store listing is named Ryndix: FBA Product Verdict and the bundle ID is com.ryndix.scan.
How is the app different from the published case studies?
The published category reviews are method demonstrations on real Amazon US categories, written out in full and free to read. The app is the self-serve version of the same decision card, applied to a product you scan yourself. The walking pad review is the worked example of the method the app runs.
Is the app available in my country?
Downloads depend on your Apple Account storefront. The app is listed in 172 countries or regions, but it is not currently available on the China mainland App Store, so mainland China accounts cannot download it.
Who handles a refund for scan credits?
Scan credits are sold by Apple, so refunds are handled by Apple through reportaproblem.apple.com, not by Ryndix.
How do I delete my app account?
In the app: Account, then Delete Account. That removes the profile, scan history and unused credits; the retention limits are documented on the privacy page. Support requests go to [email protected].
