🍣 For conveyor-belt sushi, restaurants & all-you-can-eat

How many pieces did everyone eat? Let the counter say.

Someone creates a table, everyone else joins with a 4-character code, and from then on the whole table sees, live, how many pieces each person has had. Great for sushi restaurants, conveyor belts (kaiten-zushi), and all-you-can-eat buffets — for bragging rights, friendly competition, or just knowing how much the table ate.

How it works

Four steps, no sign-up, without ever leaving the table.

1

Create a table

Open the app, give it a name, done. SumSushi gives you a 4-character code for that table.

2

Share the code

Everyone else types it into their phone to join. As soon as you're in, you see who else is at the table.

3

Tap to count

Every time you grab a piece, tap the nigiri. Your counter jumps instantly, and everyone sees everyone's count, live.

4

Compare the stats

You can see who's ahead at any moment. When you're done, a summary with the total and each person's share closes out the table.

No internet, no servers — really

SumSushi has no backend: the phones at the table talk directly to each other over Bluetooth Low Energy. It works just as well on a sushi belt with zero signal as it does in your living room.

Why SumSushi

A small, honest app: it does one thing, and asks for nothing in return.

No server

Not a single byte travels over the internet. Everything runs over Bluetooth, straight between the phones at the table.

Real privacy

No data from anyone is collected or processed. No analytics, no tracking. Read the privacy policy.

No accounts

No sign-up, no passwords. The only thing the app asks for is a name — whatever you want it to be.

Works with zero signal

Great for spots with bad wifi or basement restaurants: Bluetooth doesn't need a single bar.

No ads, ever

A one-time payment of $0.99/€0.99 and that's it: no ads, no subscriptions. We'd rather charge once than fill your screen while you eat.

Live stats

Every diner can see, at any moment, how many pieces they and everyone else at the table have had: great for curiosity — or competition.

Inside the app

Cozy, simple, and built to use one-handed while you eat.

Frequently asked questions

What exactly is SumSushi for?
For keeping a live count of how many sushi pieces the whole table has eaten. It doesn't calculate prices or split any amount — it's a shared piece counter, built for per-piece sushi restaurants, conveyor belts (kaiten-zushi), and all-you-can-eat buffets, where what matters is how much each person ate.
How much does it cost?
$0.99/€0.99, one-time payment. No ads, no subscriptions — pay once and it's yours for good.
Do I need internet or mobile data?
No. SumSushi runs entirely over Bluetooth Low Energy, directly between the phones at the same table. It doesn't use wifi or mobile data for any of this.
How many people can join a table?
A whole table, up to about 8 diners at once, each with their own color in the list.
What happens if my phone locks or I step away for a moment?
You reconnect automatically when you're back and pick up your same counter, without duplicating your row. If the app fully closes, it recovers your table on its own when you reopen it.
What data does SumSushi collect?
None. There's no server to send anything to, and no analytics inside the app. All the details are in the privacy policy.
What devices does it run on?
SumSushi is a native iPhone app (iOS 26 or later). Everyone at the table needs the app installed and Bluetooth turned on.
