I've just recently thought about dating as well. I have been separated from my AXH for almost 2 years as well and going through a divorce. He already has moved on (surprise, surprise). I have also tried the online dating app. I was into for about a day then I realized it wasn't for me. I just keep telling myself that God will put the perfect man for me right in my path. I would suggest to just be patient (even though it's hard) and let destiny take it's course.
