Built an AI shopping list after my wife promoted me to Head of Weekly Shop
I recently took a couple of weeks of annual leave, and instantly my wife promoted me to Head of Weekly Shop.
I spent 45 minutes writing a "proper" list, did 3 full laps of the supermarket hunting down everything on it, came home two hours later feeling pretty pleased with myself... until Laura reminded me I forgot dishwasher tablets and the bear card things the kids like. So we built an app to fix it.
For two weeks, Laura became unofficial Head of Product, telling me exactly what was annoying her about the shop. Me and my pal Claude, who luckily was also on leave, would build it. Laura would test it, pick it apart, and we'd go again.
What we ended up with is plenti. It started as us just trying to stop forgetting dishwasher tablets, but the problems and the fixes kept coming thick and fast, so a list turned into an app.
It's a personalised AI shopping list that learns what you actually buy and builds it for you in seconds. No more 45 minutes writing it out, no more 3 laps of the shop hunting for things you missed. Works standalone, but if you're a Sainsbury's shopper it connects straight to your account and gets even better.
It's iOS in the UK only for now (sorry), but it's live on the App Store. Small subscription on it, purely so the AI running costs don't quietly bankrupt me: £1 covers your first shop, then £7.99/month if you stick with it.
If you, or anyone you know, does the weekly shop (willingly or otherwise), I'd genuinely love for you to try it and tell me what's broken. Also happy to talk through the build, it's Supabase, Expo, and the Claude API doing the heavy lifting.
