The only active modification for Amino, originally released on May 31, 2023. Now open source.
It has a wide range of useful features. You can read more and view screenshots on Havoc. The project has been discontinued and has not received new features or QoL updates since August 7, 2024, when its biggest update was released (see the changelog...). Feel free to explore the code or create your own forks.
Amino introduced AppAttest in version 3.25.0 and enforced it as of June 22, 2024, which means you can no longer use the sideloaded app. With Eevee Amino Tweak 6.0, you can spoof your device as an Android and let it handle certificates on its own. However, it requires you to enter a Firebase AppCheck token every 24 hours, obtained from a rooted Android device. You can also open aminoapps.com links in the app with Open in Amino Safari Extension.
