PREVIEW
Download freely, then verify your email in the app for welcome credits while signup places are available.
On a computer? Scan this with your Android phone to open the same download.
Before installing, carefully compare your downloaded APK’s SHA-256 with the SHA-256 in the VirusTotal report. They must match exactly. A scan does not guarantee that an app is safe.
A report may not yet be available for a new release.
SHA-256 and how to check it
Loading checksum…
Windows: Open PowerShell and run the following, replacing the path with your downloaded APK:
Get-FileHash -Algorithm SHA256 -LiteralPath "C:\Users\YourName\Downloads\pocketbuilder.apk"
Android: Use a trusted checksum tool to calculate SHA-256 for the downloaded APK. Compare the entire result with this checksum and the report’s SHA-256. Letter case does not matter. If they differ, do not install that file.
Inspect the code your agent creates. Choose whether to enable assisted testing. Read the illustrated installation guide before installing, and turn scanning back on immediately if you pause Play Protect.
