Digital organization advice between coupon apps and shopping list?

Hi all! I’ve been couponing for a while now but I’m hoping you guys could enlighten me on organizing all the data.

My current routine is having my shopping list broken down by stores and what item items to get from each store. The disorganized part is that I have multiple coupon apps so I’ll write next to the item which app to redeem the coupon from.

If I happen to have a paper coupon I’ll note that down as well. It’s not that bad, but I feel like keeping track of all this could definitely be more streamlined.

Thoughts?
