Hattie Retroage, 83, says she loves using the app and definitely isn't looking for someone her own age.
The New Yorker was married for more than 25 years and though she and her ex-husband had a 'wonderful sex life', she missed the intimacy of casual dating.
And now she only dates younger guys.
Hattie has opened up about her love life and claims younger men these days get off on the idea of dating an older woman.
Speaking about her sexual escapades, the mum-of-two said: "Younger men, they get off on getting a woman off - very different from when I was younger.
"I screw, I sleep with, I make love with many men and not one of them has said, 'I want you for my life'."
The pensioner says people often refer to her as a 'cougar', but she wants to reverse the negative preconception people have of her lifestyle.
She said: "Cougars, as I see them, are not beasts of prey, they are an exquisite animal. I'm never on the prowl. I never approach a man, men always approach me."
The outgoing gran says she has a steady flow of lovers that she has connected with via dating apps such as Tinder.
Hattie first started using the app eight months ago, and says she has met close to 50 men. Wow.
Her Tinder bio says: "Hattie, 83, fascinating older beauty.
"Seeking a steady younger friend/lover for a shared life of adventure and passion. No pro-Trump and no players."
The youngest man she says she has been with was aged 19 - though she says that she thought he was older at the time.
Hattie is now dating a beau called Shaun, 33, which makes him 50 years her junior.
After separating from her ex-husband, Hattie set up an advert in the local newspaper in a bid to find younger men to sleep with.
And it didn't take long for the offers to come rolling in, with Hattie claiming she was inundated messages - and even began 'auditioning' potential suitors.
Now, almost a year on, she is just enjoying the ride.
She says: "I'm not agonising. I'm grateful that at this age and this stage that I have as many lovers as I want.
"My life goal is to change the awful, decrepit view of ageing - view and experience, and turn it into something exciting. A life-loving adventure.
"The depth of life, you can't avoid it. But the shallowness of good sex, that's what is good enough for me."
