Manhattan District Attorney Cyrus R. Vance Jr. says Brandon Kiehm (keem) used a variety of scams on at least three women he met through the dating app.
He claimed he urgently needed money for cancer treatments for relatives - in one case his sister, in another, his mother.
Vance says one victim was especially vulnerable because she was herself a cancer survivor.
He conned one woman while he was out on bail.
Kiehm also stole $13,000 from a man who hired him as a dog walker and $800 from a neighbor.
He was sentenced Wednesday after pleading guilty in October to grand larceny, identity theft and scheme to defraud.
