Knuckleflow

Cardistry, taught properly

Learn the hands,
not the trick

Knuckleflow is a cardistry school in your pocket. Thirty flourishes — fans, cuts, springs and spins — each one drawn out frame by frame so you can see exactly what every finger is doing.

See what is inside

Who it is for

Anyone who has watched someone open a deck into a perfect arc and wondered how. There are no secrets in cardistry — nothing is hidden up a sleeve — so everything can be shown, slowed down and taken apart. Knuckleflow does exactly that, from the first grip to a sequence you built yourself.

What is inside

Grip Map

Drag through any move at your own speed. Coloured markers sit on each fingertip, and three camera angles let you watch from above, from the front, or from where your audience sits.

Drop points

Gold marks on the timeline sit exactly where cards usually hit the floor. Tap one and it tells you what to do differently.

Combo Composer

Every move in the library is in your palette from the start. Lay moves onto a beat grid, pick a tempo between 60 and 140, and the app shows you which transitions flow and which need a reset.

Daily drill

Five to ten minutes: two moves you are mid-way through and one you already own, so nothing you have learned goes quiet.

Skill tree

Four levels, thirty moves. Every one of them is open from the first launch: a line under a row may suggest which move usually comes first, but it is advice, not a gate.

Deck Lab

Written guides on choosing a deck, keeping one alive, warming your hands up, and practising without picking cards off the floor.

What it looks like

Real screens from the app, not mock-ups. Swipe to see the rest.

The Today screen: the daily drill with a Run it again button, a one-day practice streak, and the move currently in progress.
Five minutes a day, hands only
The Grip Map for the Thumb Fan seen from above: a hand holding an open fan of cards, with coloured markers on the fingertips and the finger key below.
A colour for every fingertip, from three angles
A drop point open on the Thumb Fan timeline, with the hint: the thumb is halfway through the arc, slow down here, this is where cards clump.
Gold marks where cards usually drop
The Combo Composer: a ten-beat grid above three moves, two of them marked needs a reset, with the palette of moves underneath.

The Library on the Foundations level: ten moves, each with its category and length and a ring showing how clean it is, and a line under some of them naming the move that usually comes first.
Thirty moves, nothing hidden

How a session goes

Open the app, take the drill it offers, and count your repetitions with the big button so your eyes stay on your hands. Mark each move as learning, getting there, or clean — you are the judge, the app never scores you. The streak forgives one missed day a week without ever taking anything away.

Privacy, briefly

  • No account. Nothing to sign up for, nothing to sign in to.
  • Everything you do stays on your device. Your progress, combos and sessions never leave it.
  • No analytics, no advertising and no tracking. The one thing the app ever asks for is permission to send reminders, and declining changes nothing else.

Works with the phone face down

Every move, animation and guide ships inside the app. Put the phone in airplane mode on a train and Knuckleflow behaves exactly the same.
