I waste 2 hours every Sunday meal-prepping for nothing

ok so every sunday i spend like 2 hours cooking for the week and by wednesday half of it is in the trash bc i got bored of eating the same thing. i wish there was an app that took whatever i already have in my fridge + my macros and gave me a meal prep plan that actually varies day to day. not another recipe app, i have 5 of those. something that plans the ACTUAL week and tells me exactly what to batch cook. does this exist??
