My 19 month old is not talking & sometimes it worries me

Ok so my daughter is 19 months she is very smart , playful & happy . She loves to laugh , play on her ipad & her favorite show is "Word Party" on Netflix (Her father & I are over it lol) Buttttt she is NOT TALKING . Sometimes it worries me but then sometimes it doesn't. She is able to play "smart shapes" on her ipad which is a learning game that teaches your child shapes & colors . She also can play a Alphabet learning game that teaches your child letters & words. & for a 19 month old she exceeds at both. She brings us her juice cup ,walks is to the kitchen , to the fridge , closes the fridge but wont say "Juice" . She points to what she want . She brings us the ipad if she needs help. Come get us if her show goes off . Plays w/ her toys by herself but my baby is just not talking . Im accepting all comments, opinions & all because I just don't get it . The only thing she says clear as day is "Daddy". She was walking by 1 . She feeds herself . Off her bottle & paci . We took her to the dr for her 18 month check up & the dr at first offered to get her tested as far as speech once we mentioned she wasn't talking but once she seen her on her ipad w/ her learning games her exact words were "there's nothing wrong with her" just to be more reality based w/ her like point out red around the house (so on & so forth) to just talk more to her but both her father & I both do . Any tips ?
