A product name and a release version answer different questions. The name helps identify the app. A version describes a release within that product's own versioning system. Numbers such as 91, 365 or 777 in a supplied name should not be treated as the current version.
Match the package first
Before comparing releases, establish that both files belong to the same app. Look for documented publisher and package information. Two similarly named products can use completely unrelated numbering schemes, so a larger-looking label does not establish a valid update.
Read each field for its purpose
File size describes a particular package, while device requirements describe what the publisher says the app needs. Neither field proves authenticity. Update notes explain changes only when they come from a relevant release source; a generic latest label is not a substitute.
Keep a useful comparison
Note the installed product, its available version information, the source of the proposed update and any documented changes. If the new source gives a different name or cannot explain the relationship, resolve that discrepancy before replacing the existing installation.
Why some fields are absent
This directory hides unverified numeric details rather than filling them with guesses. Updating a saved version field does not rewrite the app's editorial guide. Read the APK review guide for the broader source check and the installation guide for setup decisions.
Android 5+ is not a release number
The owner-supplied Android 5.0+ minimum describes the phone operating system. It is separate from the APK version. Likewise, the stated 100 MB minimum free storage is not a claim that the APK file is 100 MB. Release versions and file sizes remain empty until the owner provides them.
