Compare bowling balls
Which ball, and when.
Four cards put your balls side by side using the shots you log: where in the set each one is best, how it holds up as the lanes change, where you throw it, and whether your ball changes paid off.
- On Android, or in any phone's browser
- Pro free for your first 30 days
- No card to start
Sweet Spot Pro
For each ball, the six frames in a row where it struck most often across the three games, and how far it stays within a strike of that. Read left to right, it is a plan for the night: which ball to start on and when to change. Narrow it to one bag, one oil pattern or one house.

Ball Duels Pro
Your balls on one lane: where you stand, the arrows you hit and the breakpoint, each ball's line drawn side by side with the number of shots behind it.

Night Shift Pro
Each ball's strike rate on fresh lanes, through the transition and late in the night. The leader in each part of the night is bold, unless the gap is small enough to be chance.

Swap Story Pro
Every time you change balls: what you put down, what you picked up and why. Then the part that matters: your strike rate on the first balls before the change against after it.

Good to know
- Log the ball on each shot to fill these in. It is always optional
- A number is never hidden for being early. Thin samples are marked instead
- By Ball ranks your balls on strikes, knockdown, 10-pins and splits
- The Caddie reads the same numbers for your whole arsenal
Questions
How many shots does it take?
The cards fill in from your first logged night. Numbers built on only a few shots are marked so you know to treat them as early.
Do I have to log my line?
Only for Ball Duels, which draws where you stand, aim and break. The other three only need the ball.
Are these free?
They are part of Pro. Every new account gets Pro free for 30 days, no card needed.
