Tally Mark Counter

How the Tally Mark Counter Works

The Tally Mark Counter draws a vertical stroke for each tap and crosses every group of 4 strokes with a 5th diagonal stroke. The display shows the count as tally marks and as a number at the same time.

1. Tap to add a mark: Each tap draws one stroke, written as |.
2. Complete a group: The 5th tap crosses the 4 strokes, forming one bundle of 5.
3. Count by fives: Read finished bundles in 5s and add the loose strokes.
4. Switch styles: Choose the Western gate style or the Chinese 正 (zhèng) style. Both styles group strokes by 5.

Tally Mark Counter Formula

The Tally Mark Counter total equals the number of full groups multiplied by 5, plus the loose strokes.

Groups

Bundles of 5 marks

Loose strokes

Marks after the last full bundle, 0 to 4

Example: A tally shows 7 full groups and 3 loose strokes. Total = (7 × 5) + 3 = 38.

About the Tally Mark Counter

A Tally Mark Counter is a digital version of the 5-bar gate, the oldest written counting method. Tally marks group strokes into fives so the eye reads totals at a glance.

Tally marks date back at least 20,000 years, with notched bones such as the Ishango bone from central Africa. The 5-group pattern works on the fact that people recognize up to 4 objects instantly without counting, a skill called subitizing.
