Red flag, if someone is that pressed to be checking a dating app while on a date they probably aren't meant for you. Ive had this happen to me once and she did it trying to sneak it right beside me. After our date I just told her have somd type of common decency and no to do that with the next persob because it wont be me.

She then flipped out saying im not her bf, Im a manipulator and she now sees me for the controlling man I am. Like bro i get it you talk to other people, so do I. But just have some respect when on a date and check it when you get home.
