do i need to report gambling wins if i've lost more than won on the app i use and they didn't send me a tax form

Yes, you should report all gambling winnings to the IRS, even if the app does not send you a tax form. You can deduct gambling losses up to the amount of your winnings if you itemize your deductions.
