Anyone tried that Calm app or am I wasting money?

My wife keeps suggesting meditation and I'm skeptical but I downloaded Calm last week for like $80/year. Did 3 sessions so far and honestly the 10-minute ones actually help me wind down before bed. Not a miracle but cheaper than therapy and I can do it at 9pm without leaving the house. Wondering if anyone else uses it or if there's a better app out there.
