I have been using a website called Fishnotify and Windy.
As to where to go fishing, I've recently subscribed to TPWD fishing reports. They tell you what people have reported catching, sometimes even what bait or lures used. Salt strong has a pretty sophisticated app for finding where the fish are biting. I tried it a few years ago, but found the $100+ yearly subscription too steep for me. At most, I go fishing twice a month when I can, so I can't justify spending that much money.
