Barcodehammer is an Android app for reading and creating barcodes and QR codes, made by Eric M. Kok, Eric de Magiër.
Three lengths, each in a block of its own, so you can lift one out without cutting and pasting. The texts are meant to be used word for word.
Barcodehammer scans and creates barcodes and QR codes. Everything happens on your own device: no account, no sign-in, no ads.

Pro is a one-time purchase, not a subscription, and adds four things: the ticket vault behind your fingerprint, bulk scanning with counts and an Excel list, SVG and PDF export, and searching a shared PDF. That PDF gives you every code on every page as a list: save it as text, or put the whole group into the vault at once under a name you choose. Exporting and sharing then runs at 2048 instead of 512 pixels.
The line is never drawn at the type of code: every code can be created, read and shared in both versions.

Tickets sit in an encrypted file of their own. Its key is wrapped by a key in the Android Keystore that can only be used straight after a fingerprint, face, PIN or pattern. So the lock does not sit in front of a screen you can skip: without that confirmation there is nothing to read, not even for someone who takes the file off the device. That takes Kotlin code of its own and Android 10 or newer; if it cannot be done, the app says so and builds no vault.
There is no account and no sign-in, and there is nothing to sign in to: there is no server behind the app. Scanned codes and the history stay on the device. The app shows no advertising, in neither version. The one-time purchase runs through the Play Store app on the device.
The built app file contains the INTERNET permission.
Barcodehammer does not ask for that permission itself and makes no connection
of its own: Google's scanning library puts it in its own manifest and the
merger takes it over. The app and this site say so in as many words instead of
promising "offline", because someone who reads through the permissions should
not come across anything there that has not been told.
A code appearing neatly on the screen says nothing about the content. For a scanned code the app therefore does not report that it is valid: the recognition of the operating system only hands over codes with a correct check digit, and a tick would be false reassurance. For typing something in by hand that check does make sense, and there it is.
