Taken from the readme of the app on github:
The current release provides only basic functionality, with several key features to be introduced in future versions, including:
App and device verification based on Google Play Integrity API and Apple App Attestation
Additional issuance methods beyond the currently implemented eID based method.
These planned features align with the requirements and methods described in the Age Verification Profile.
There is an issue opened to remove this as it’s basically telling us that to verify our age in the EU an American corporation has the last word, making it not only a privacy nightmare but a de-facto monopoly on the phone market that will leave out of the verification checks even the fairphone (european) with /e/os.
There is no app. Read the readme from the beginning. Even cited it here. Show me the he app in the app stores! YOU CAN’T!
THIS IS A REFERENCE IMPLEMENTATION NOT AN PRODUCTION READY APP! THIS IS EXPLICITLY STATE ON THE PROJECT README!
