Pin the digit as it rolls.

A moment of precision, then a result.

Chikinion trains reaction and digit precision through offline graded drills.

One reel, three commands.

The live digit moves against a lit Prompt. Watch the reel and pin when the two match.

The session timeline records what happens as you practice.

Start a generated drill on an axis.

Tap when the live digit matches the Prompt.

File the result after a successful pin.

Each result receives a grade from S to D and updates its axis. Progress keeps the five-arm radar and past results together.

After five results, drills spotlight the weakest axis until its rolling mean exceeds the next-weakest.

Choose a local Program to change axis emphasis. Roll speed adapts to recent grades, and Settings lets you tune its bounds.

Chikinion keeps its drills, Programs and history on the device, with no account or cloud sync.
