For me personally, I have a dry-erase board on my fridge and will note expiry/bb dates for items that are only fresh for a short time (i.e. the bread or almond milk I make). That way, everyone in my home can see it.

Pretty much all other food items like spices, flour, pantry ingredients, and frozen food are stocked in quantities that I would be able to use well before they "expire" (or diminish in quality). Some of these foods are fresh for years, so it doesn't really worry me that they'll go bad or anything.

Unless you've got a warehouse of food with moderate shelf life, I think there might be an easier way to do things without using an app, which I find just overcomplicates things. But even a simple spreadsheet, as already suggested, might be an easy option. Just my 2 cents.
