Better apps for FWB?

After meeting with a few women in my age range I have come to the conclusion that a long term relationship is not realistic for a newly divorced 66 yo. I think a special friendship is more honest.

I spent 20 years in a sexless marriage and I dont want myself or the woman to get too comfortable about not pleasing the other.

Is there some other dating app where fwb arrangements are more common than on Bumble?
