ABC mouse

Has anyone tried ABC mouse with their toddler? On their website it says it's $60 for a year, which is less than what I pay for Netflix (that I hardly ever use.) I feel like it's a good deal but not sure how much it helps. I'm a stay at home Mom and always looking for new and fun ways to teach them. Also, what age would be the earliest to start?

Thanks ladies! Their 2nd birthday is around the corner I may have to get a second tablet for their birthday and get it! They don't understand phones or tablets too well but then again they don't get much screen time, so I'm sure with a little time it'll kick in😊
