I recently bought a refurbished OnePlus 6 for €75 off EBay. LineageOS works like a dream.

PopOs! Familiarity, stability and the fact that it fulfils 95% of my needs perfectly.

My wife and I use SimpleNote. I know it’s not a proper grocery app but it works really well. One person can create the grocery list initially then share with another. Either of us can then add to the list if we think of things we need or tick the box if we have bought it. Instantly updated on each others tablets, phone, desktop automatically. It’s free too!

I have proton for many years since I started de-googling. Very happy with it.
