Shot Focus Bowling vs Bowldyna Studio

Shot Focus Bowling is the all-in-one practice, league and tournament companion built for serious bowlers. Whether you're grinding spare shooting on a league night, breaking down your form on video, or dialing in your starting board for a fresh oil pattern — Shot Focus gives you the tools to understand your game at a deeper level and improve faster. SHOT TRACKING & SCORING Log every frame with a full digital scorecard and tap-to-select pin interface. Record the ball you used, pocket hit type, splits, and lane assignment for each game. Every shot builds a practice history you can analyze over time. LANE SIMULATOR Enter your breakpoint distance, breakpoint board, and arrow target — Shot Focus instantly calculates your slide board and setup position. Switch to Spares mode to map the perfect angle to any pin combination. Built-in pattern visualization shows oil zone and board highlights for any house or sport condition. VIDEO ANALYSIS Record or import video of your approach, trim to the exact swing you want to review, and draw reference lines directly on the frame. Build a visual library of your form over time and spot trends you'd never catch with the naked eye. SKILL CHALLENGES Structured practice drills that score your spare shooting accuracy, consistency, and focus — the same way a coach would. Track your results session over session and watch your conversion rates climb. ARSENAL MANAGEMENT Build a detailed profile for every ball in your bag — weight, RG, differential, cover stock, drilling layout, PAP, and surface finish. Compare performance across balls in any condition and know exactly which one to reach for. SCORE & SHOT ANALYSIS Deep stats across every session: running average, high game, low game, strike %, spare %, pocket hit %, balance, drift, and accuracy trends. Arsenal Analysis shows how each ball performs in head-to-head comparisons. LEAGUE TRACKING Look up your USBC league or any league on leaguesecretary.com, track your series and average across a full season, and keep your stats in one place alongside your practice data. PRACTICE CALENDAR See every practice session on a visual calendar. Identify gaps in your training schedule and stay accountable to your improvement goals. CLOUD SYNC Sign in with Apple or Google and your entire profile — balls, sessions, games, league data — syncs across all your devices automatically. Never lose your data.

Bowling, from feel to physics. Bowldyna Studio measures your throws from video and puts those numbers straight into a physics simulation — what actually happened, and what would happen if you changed something. Record a throw and the app measures ball speed, rev rate, axis rotation and the path down the lane. Once enough throws are in, it estimates the oil on that lane and proposes, for each throw, where to stand and where to aim. "Why did that miss the pocket?" "Why does the same line hook differently from one game to the next?" "How much does rev rate — or the oil pattern — really change the path?" Bowldyna Studio turns differences you can only feel into a path, a number, and a mechanism you can look at. THROW ANALYSIS - Analyze a recorded video, or run the camera live - Automatic ball speed, rev rate, axis rotation, axis tilt, release board and launch angle - Breakpoint, pocket position, entry angle, pins contacted and pins fallen - Calibration is four points traced onto the lane edges - A clean lane picture is built automatically, with people and the ball averaged out, so the points land on the lane edge - Within a session, the next recording starts from the four points you already set - One visit is one session: throws accumulate instead of scattering - Export the analysis as CSV - Everything runs on the device. No video is uploaded anywhere LANE OIL ESTIMATE (Pro) - Works out where the oil was depleted and where it was carried down, from your own throws - Heatmap of the estimated oil change - The gap between simulation and measurement, before and after the estimated oil is applied, in boards - The confidence of the estimate, and how much of the lane it accounted for - After an estimate, every throw gets a strike course drawn over its measured path — changing only where you stand and where you aim - Hand the measured lane straight to the simulator SIMULATION - Ball speed, rev rate and rotation direction - Release board, launch angle, axis rotation and axis tilt - House ball / my ball - Ball library for keeping several balls - Coverstock, surface, RG, differential, core, PAP and layout - House, flat, short, long and custom lanes - Lane library for custom lanes - Oil pattern visualization - Breakdown and carrydown, overlaid - Continuous skid, hook and roll - Ball path, pocket position and entry angle - Ball-to-pin and pin-to-pin collisions - Full lane view and pin deck view - 3D View (Beta) for pin action - Strike / spare route search (Beta) - Edit standing pins and target pins - Save and load throw conditions and profiles - 12 languages FREE Throw analysis from recorded video and from the camera, the core throw settings, path simulation, the house and flat lane presets, and the result readouts. Strike / spare route search (Beta) is free for now as well. BOWLDYNA PRO A single in-app purchase permanently unlocks the lane oil estimate, detailed ball specifications, PAP and layout, custom lanes, breakdown and carrydown, pin physics, 3D View (Beta) and the other advanced controls. There is no subscription. The current version shows no ads. RECORDING TIPS Put the phone on a tripod or something else that will not move, and frame the whole lane from the foul line to the pins. 60 fps is recommended; 30 fps costs rotation accuracy. A ball with visible patterns or logos measures far better than a plain dark one. PLEASE NOTE Bowldyna Studio does not guarantee any particular result or any improvement in your score. Measurements and estimates alike carry error from the lane surface, from oil that keeps changing, from the condition of the ball, from your release, and from how the video was shot. The confidence shown by the strike / spare route search describes how stable a line is inside the current simulation model. It is not a promise that the line will strike on a real lane. Treat what this app measures and simulates as a way to study your throws and understand the physics of bowling.
