TenthFrame: Bowling Scores

Pin-level stats for league bowlers — no subscription.

TenthFrame records every game frame by frame, then turns years of league nights into stats that actually match the numbers in your notebook.

Score a game in one tap per ball, or tap the pins you leave standing for pin-by-pin detail. TenthFrame reads the deck and flags real splits from the pin geometry — head pin down, remaining pins in two or more non-touching groups — not from a fixed list. The 10th frame, fouls, and fill balls all follow standard ten-pin scoring rules.

STATS THAT MATCH YOUR NOTEBOOK
Every number uses one written-down formula (spelled out in Help), so it lines up with the way you count by hand:
- Strike rate = strikes ÷ first-ball opportunities (a ball to a fresh deck in the 10th counts too)
- First-ball average = first-ball pinfall ÷ frames (fill balls excluded)
- Single-pin spare conversion = single pins you picked up ÷ single pins you left
- Spare conversion, plus game and series average (scratch or with your handicap)
Filter every stat by date, league, house, or ball, and watch the trend line move.
