New: Your Balls and Line Learn From Your Games
For each oil pattern, the app compares how often you strike with each ball and shows your strike rate right on the ball cards. With Pro, your results factor into grade and rank, along with a reason. With Plus, the Pattern Briefing cites real numbers from your games.
Line Tracking
Set your stance and target board, make moves mid-game with one tap, and keep your history in view. With Pro, your starting line adapts to the lane condition, and "Your Experience" in pattern analysis shows your proven line and what your moves get you.
Lane Condition During Your Game
View the oil pattern while you bowl. With Pro, set the lane condition yourself or let the app detect it, and coach tips and ball picks adapt. Entering how many bowlers are on your lane makes the estimate more accurate.
Drills Overhauled
Condition Ladder is fully playable, Pattern Scout suggests patterns you haven't bowled yet, and Pattern Scout, Transition Tracker, and Ball Comparison each have their own notes field.
Name Your Sessions
Custom names like "Week 8," with quick suggestions and renamable anytime.
