Check your copy

On any computer with the downloaded file:

sha256sum gibbr.apk  (Linux/Mac: shasum -a 256 gibbr.apk)

The output must equal the hash above, character for character. One byte different means the file was modified — delete it and download again from gibbr.app only.

On-chain anchor Base

These hashes are written into a Base blockchain transaction. Nobody — not even us — can quietly change them after the fact: the anchor is permanent, public, and timestamped by the chain.
