Description

YASNAC, or Yet Another SafetyNet Attestation Checker, is an Android app designed to showcase the functionality of the SafetyNet Attestation API. This API allows developers to verify the integrity and security of Android devices. YASNAC utilizes an API key with a daily quota of 10,000 requests. Once this quota is reached, users will encounter an error and will be unable to utilize the app until the quota is reset the following day. Developed using Jetpack Compose, YASNAC offers a modern and efficient user interface. Jetpack Compose is a declarative UI toolkit for building Android apps, which simplifies the process of creating interactive and visually appealing interfaces. The source code for YASNAC can be found on GitHub under the repository name "RikkaW/YASNAC". YASNAC serves as a valuable tool for developers looking to explore the capabilities of the SafetyNet Attestation API. By providing a simple and intuitive interface, users can easily understand and test the functionality of this API. With its daily quota limitation, YASNAC ensures that the API key is used responsibly and prevents excessive usage that could potentially impact other users.

**SAFETYNET API HAS BEEN DEPRECATED BY GOOGLE. THE APP WILL NO LONGER WORK AS INTENDED** The app was great and all, it was clean and used to show the exact details i needed to ensure safetynet... but upon Google discontinuing the api, I can't find any other tools to attest their new play integrity api... hope to see another app like this from this dev soon...

Beautiful app. Every other app in existence: take notes. Make it simple to use, ad-free, and follow system theme. This is a good pair with the inware app.
