Meet your new tiny friend

He's got eyes for you.

Pump Buddy is a pocket-sized round-screen friend for your keys. He blinks, he sulks, he counts your reps, and he remembers you.

Move your cursor or finger. Tap his screen. Pick a look.

The real thing

Not just pixels. He's real.

A hand-finished star shell around a round screen. Here he is on a desk, counting down a rest and keeping score of the day's steps.

FAQ

Good questions.

What does pre-order mean, and when will mine ship?

Each Pump Buddy is built and tested by hand in small batches. Batch 1 is 20 units and ships within 2–3 weeks of your order. If anything slips, we email you before you have to ask, and you can get a full refund any time before he ships.

How long does the battery last?

His 2000 mAh battery gives approximately 28 hours of use per charge. He charges over USB-C, so a top-up is quick and uses a cable you already own.

Is he waterproof?

[TBD: water resistance rating]. Until it's confirmed, keep him away from swimming pools and showers.

How do I change his colours?

Plug him into your PC and use the Windows control app. Pick the eye white and each pupil, save up to 8 looks, and switch between them whenever you like.

Does it work on Mac or Windows?

The control app runs on Windows. [TBD: Mac support]. Once your colours and skill wheel are set, he works on his own without a computer.

What's in the box?

Pump Buddy, a USB-C charging cable, [TBD: keyring / clip] and a quick-start card.
