I was going to recommend VoltPay, but it looks like voltpay.app just redirects to google's home page now... so, nevermind on that.
I use Zeus wallet and Alby to hold my coins. It's fasy and easy. Using just Zeus and holding the coins myself would be nice, but it is poorly documented, so much so that a person who has been using BTC since 2012 isn't comfortable with it.
