Shopping lists you can hand across the room.
Jot a shopping list, put an approximate price against each item, and watch the running total. When you're both at the shops, point one phone's camera at the other's screen — the whole list jumps across your Wi-Fi and merges into the list already there.

A shopping list, and a quick way to share it.
Make as many lists as you like. Add items on one line, tap to tick them off, swipe to remove, and nudge a quantity with the − and + buttons. Clear what you've ticked, untick the lot, or duplicate a list for next week — and there's an undo when you slip.
Give each item a rough price and a quantity. Listaity keeps a running total in the header so there are no surprises at the till.
The receiving phone shows a code on its "Receive Mode" screen. Scan it from the other phone and the list is on its way.
The list goes straight from one phone to the other on your local network. Nothing is uploaded and there's no server in the middle.
Not on the same Wi-Fi? Tap Share and send the list any way you like — email, a message, a cloud drive. Open it in Listaity on the other phone and it merges just the same.
New items are added to the matching list on the other phone; prices and quantities it already has stay put, and ticked-off items sync across so both lists agree on what's still to buy.
Tick “keep the other phone in sync” at the top of a list and sharing also removes anything the other phone has that isn't on yours — so the two lists end up identical. Off by default.
After the first QR scan the two phones remember each other. Next time, the receiver just opens “Receive Mode” and the sender picks it straight from a list — no code.
Start typing and Listaity suggests items you've added before, with their last price and quantity. Suggestions survive clearing a list, and you can edit or remove them in Settings.
Give the phones you share with familiar names, and pick one of six colour palettes from Settings.
No account, no analytics, no internet — only your local network. Each phone has its own certificate and pins the other's, so the transfer is TLS-encrypted end to end, and a paired send can't be replayed or redirected.
Both phones on the same Wi-Fi, both with Listaity installed.
On the phone that should get the list, tap Receive Mode on the Lists screen. It shows a QR code and a short pairing code.
On the other phone, open the list you want to send, tap Send, and point the camera at the code.
The list folds into the matching one on the first phone — new items added, ticked-off items synced. Both phones show what changed. From now on those two phones can skip the scan.
Download listaity-debug-b10.apk, allow installs from your browser or files app, and open it. Install it on both phones. This is an early sideload beta — a debug build, not on the Play Store yet — so the QR sharing is the part most worth trying.
