Ventoid is an Android app that prepares Ventoy-style bootable USB drives over OTG, using a bundled checksum-verified Ventoy 1.1.18 release. It is an independent GPL-3.0-only project released on F-Droid, with no ads, analytics or network dependency for normal use. It requires Android USB host support and a visible USB mass-storage device, and it does not download ISO files.
