YASNAC (short for Yet Another SafetyNet Attestation Checker) is an Android app that demonstrates SafetyNet Attestation API.
The API key used by YASNAC has a quota of 10,000 times per day. If the quota is exhausted, you will see an error and you will not be able to use it until the quota is restored the next day.
YASNAC is written with Jetpack Compose. You can find the source code at GitHub (RikkaW/YASNAC).
