The global
hamster wheel
championship

Every turn counts. Clip the tag to the wheel and your hamster's speed, distance and records go straight onto the world ranking — while you sleep.

01 · How it works

Mount, plug, sleep.

Two pieces of hardware and zero setup. No pairing, no app running in the background, no phone left by the cage.

Step 1

Mount the tag

A coin-sized gyro tag clicks onto the outside of the wheel with the mount for your wheel size. Works on any wheel — plastic, wood, metal, flying saucer.

Step 2

Plug in the gateway

A small listener by the cage picks up every rotation the tag broadcasts, 24/7. Phones can't scan Bluetooth in the background — the gateway can. It ships with every tag.

Step 3

Wake up to the numbers

Distance, top speed and personal bests are computed server-side and land on the leaderboard. Hamster days run 12:00–12:00 so a night run is never split in two.

02 · The tag

Measure while you sleep.

Hamsters run at night. The tag sits on the wheel, the gateway listens by the cage, and the numbers are waiting in the app in the morning.

Season 1 hardware

“Nisse ran 2.3 km last night” — without the app even being open.

A coin-cell gyro tag on the wheel broadcasts every rotation over Bluetooth. No pairing, no app in the background, no phone left by the cage at 3 AM.

Sensor

Gyro, not a magnet

Measures rotation directly, so it works on any wheel — plastic, wood, metal, flying saucer — with no counterpart to align.

Battery

Months on a coin cell

Low-power firmware sleeps between laps and reports its own battery level, so the app tells you before it runs out.

Privacy

Nothing to pair

The tag only broadcasts. No connection, no account on the tag, nothing to configure on the wheel.

Leaderboard

Race the world

Season standings by species and wheel size. Your hamster's night run shows up next to hamsters in Tokyo and Toronto by breakfast.

03 · The feed

Every night, on the board.

This is what season 1 looks like in the app: each night's run lands in the feed and on the world ranking by breakfast. The names below are sample data until the first tags ship.

Ranking

World cup and home league

Standings by species and wheel size, plus a home league per country. Your hamster's night run shows up next to hamsters in Tokyo and Toronto.

Records

Personal bests, automatically

Longest night, top speed, longest streak. The tag measures, the app keeps score.

04 · Health

Health, not just speed.

Reduced wheel activity is one of the earliest illness indicators in rodents — well established in laboratory animal science. A baseline turns a toy into an early-warning system.

Baseline

14-day rolling median

Every hamster gets its own normal. Seasonal, age and species differences are built in.

Alerts

Deviation alarms

“Nisse ran 60 % less than usual three nights in a row.” Simple statistics, genuinely useful.

Vet

Exportable history

A one-page activity report you can hand your vet — the kind of data they never get to see.

A baseline needs every night, not just the ones you remember to check. Reserve the tag →

05 · FAQ

Questions

Is it safe for the hamster?

The tag weighs about as much as a coin and is fixed on the outside of the wheel, away from the running surface. The battery compartment is sealed — hamsters chew on everything, and we design for it.

Which wheels does it fit?

Standard spoked wheels, solid wheels and flying saucers — the tag ships with a mount for your wheel size. Tell us your wheel diameter when you reserve and the right mount is in the box.

Do I need the gateway?

Yes. Hamsters run at night and phones don't scan Bluetooth in the background, so the gateway is what makes 24/7 measurement possible. That's why it ships with every tag — there is no tag-only option.

When does it ship?

Reservations fund the first production batch. No payment is taken now; we email you with a firm date and price before anything is charged, and you can cancel any time.

Which phones does the app support?

iOS and Android. The tag doesn't care which phone you have — the gateway does the listening, the app just shows the numbers.
