About this app
Five balls. One oil pattern. Which one do you throw tonight?
Strike Zone is the bowling app for league bowlers and serious hobby players – your digital bowling coach with ball database, arsenal analysis, oil pattern strategy, score tracker, and AI coaching.
Bowling Ball Infos
Over 3,000 bowling balls with complete specs: core, cover, RG, differential, MB. Slot assignment and personal fit recommendation for your player type and arsenal. USBC status at a glance.
Arsenal with 8-Slot System
Every bowling ball is automatically assigned to one of 8 slots – from Tank (heavy oil) to Spare. Arsenal analysis with grade breakdown, lane condition spectrum, and an interactive arsenal map. Add the same ball multiple times with custom names for different layouts (league, backup, spare ball).
Ball Recommendations & Comparison
Personalized bowling ball suggestions based on your player type and arsenal gaps. Compare up to 6 balls at once with radar chart and specs table. A neutral second opinion – no pro shop sales pressure.
Oil Pattern Coaching
Over 1,300 oil patterns with analysis and coaching tips. Line play, target arrows, breakpoint, and speed recommendations for fresh, carrydown, and burn. A–E grading for every bowling ball on every oil pattern. Pattern logbook for personal notes on each lane.
Game Tracking & Score Tracker
Frame-by-frame scoring with visual pin display. Foul tracking, ball changes, game notes. Formats: multi-bowler, Baker Doubles and Team, Scotch Doubles, No-Tap. Match Play with opponent score for league competition. Pocket hit tracking for high, flush, light, and Brooklyn.
Bowling Stats
Average, high game, trends. Strike rate, spare rate, split conversion, single-pin rate. Spare heatmap with color-coded hit rate per pin. What-if analysis. Breakdowns per ball, per oil pattern, per location. Season statistics. Export as CSV or PDF.
Training Center & Bowling Practice
Live Coach gives real-time tips after every frame in practice. Spare tips with the 3-6-9 system, lane adjustment cues, ball switch suggestions. Skill Tree with 4 areas and 5 levels. Drills, weekly quests, XP system, and algorithmic training plans.
Challenges & Community
Challenge other bowlers – as a 1v1 match or open challenge. Play your game, share the link. The opponent's score stays hidden until after you play. Find bowlers near you, compare arsenals and stats. Public bowler profiles with deep links.
Ball Management & Layout Editor
Surface tracking with resurface phases. Layout editor with 4 systems: PAL, Dual Angle, VLS, 2LS. Document drilling sheets as photos. USBC flag for tournament-ineligible balls – know which balls are USBC-approved for sanctioned league and tournament play.
