Lane Lab: Bowling Practice

Bowl with a plan, without giving up your data. Lane Lab is an offline practice journal for ten-pin bowlers. It turns your own score, roll, and pin-leave history into a focused next-practice plan, while also providing the scorekeeping and gear records needed to make that plan useful. One paid download includes every feature—no subscriptions, ads, accounts, or required internet connection. Plan your next practice in Lane Lab • Lane Lab reads only the rolls and leaves you record on your device, shows the evidence behind each focus, and suggests a practical next step. • Save a suggested focus or create a custom practice plan, tap Start Practice to create its linked bowling session, and mark the plan complete after that session is finished. • Build a baseline before drawing conclusions, or focus on spare conversion, open frames, first-ball carry, and split decisions when your own sample supports it. Fast, flexible scoring • Record a final score, enter pins per roll, or capture the exact pins left standing. • Automatic ten-pin scoring with strikes, spares, fouls, splits, tenth-frame bonus rolls, handicap, Current Frame Scoring, and Baker team play. • Score 1–8 bowlers and 1–12 games in a session. • Autosave after every valid entry and resume an unfinished session at any time. • Correct any completed frame and let Lane Lab recalculate every dependent score. Stats that help you practice • Track average, high and low games, first-ball average, clean games, 200/250/300 games, and score distribution. • Review strike rate, spare conversion, single-pin spares, open frames, splits, and common pin leaves. • Filter the analysis by bowler or bowling ball and inspect score trends, pin leaves, and ball performance. • Get transparent on-device practice insights with sample-size gates—no cloud AI. Your bowling gear and history • Catalog bowling balls with weight, surface, layout, RG, differential, photos, notes, and status. • See each ball’s games, average, high score, strike rate, and related sessions. • Organize bowlers, teams, bowling centers, event types, tags, and reusable session templates. • Search and filter your complete history, then open any game for a frame-by-frame review.
