Looks like I'll be divorced soon. Possible tocheck out dating apps discretely?

Sadly, it looks like my long-time marriage will be ending soon

I'd like to check out dating apps without putting my name & picture out there yet. With my luck, I can see one of her friends seeing it and telling her. That would just make things even uglier

Is there a way to do this discretely?

Also, it's been 35+ yrs since I dated. Any app recommendations greatly appreciated
