POCKETBUILDER / DOWNLOAD

Get PocketBuilder App

For Android 10+ · ARM64. Not available for iPhone or iPad.

Installing outside Google Play (sideloading)
Android may warn you or ask you to allow installs from your browser. Only install files you trust. Keep Play Protect enabled.

Checking APK details…

Download APK ↓

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.
