Answer three questions — what can go in the box, what has to stay out, how picky they are — and Lunchbox Tin builds the week, matches what goes with what, and hands you the shopping list.

How it works
No blank screen, no setting up a database of your child's food before you get anything back.
Cold only or is there a microwave. Nut-free, dairy-free, whatever your school and your kid need.
A main, side, fruit and sweet for every pack day, arranged so each box actually works together.
One shopping list grouped by aisle. Each morning, a checklist of exactly what goes in the bag.
What's in it
Not a random draw. Crunch against a soft main, protein when the main is light, something tangy to cut the salt — and it tells you why each box was built that way.
Nut-free, dairy-free, cold-only, plus anything else you list. Excluded foods are flagged in your list, never silently dropped, so you always know why something stopped appearing.
Every planned box rolls into one list grouped by aisle, with quantities. Tick off what the pantry already has and shop the rest. More than one kid? One list covers them all.
The next school day as four things to tick off, with a flag when the box needs an ice pack, a sealed container, or is missing any protein.
On your phone
Designed at phone size first, because that's where lunch actually gets planned.
Install it
There is no app to download. Add it to your home screen and it opens full-screen with its own icon, works with no signal, and keeps everything on the device.
What's coming
Sync between two parents' phones, a much bigger idea library, and a reminder the night before are what's next. Leave an email if you want to hear when they land — that's the only thing this page collects, and it's used for nothing else.
