Alby works great with Amethyst. I have it configured for automatic Zaps. You'll need a desktop to set up Alby though. Once it's setup, you can configure #[8] for Android for easy mobile payments beyond just using automatic Zaps in Amethyst. Alternatively, you can use Wallet of Satoshi.

I will setup your recommendation it sounds good, but for the time i will take the wallet of satoshi! Thanks
