Sex Apps

I’ve heard of apps for couples where you swipe either way on sex things you want to try. Does anyone know what it’s called or know of other sex apps out there?

Mine isn't so much a sex app, its called tiny decisions (ios), its a spinning wheel that you can make up whatever you want, e.g. I have a his and a hers wheel with things like massage, spanking, oral, tickling, masturbation etc. you click the button, the wheel spins and lands on an activity, do said activity, rinse and repeat.

Adds a bit of playfulness to some sex sessions, although we don't get the opportunity as much as I'd like

It could be Nookii or Kindu https://www.lovehoney.co.uk/blog/2018/02/16/6-apps-that-will-shake-up-your-sexual-routine/

I saw one called Desire recently which I thought was worth a look…
Have used Kindu before that was a good laugh and let you add custom entries to the pre-made lists…
