ProVelocity Swing Analyzer vs Sideline Score

ProVelocity turns your phone into a precision swing analyzer. Using advanced acoustic detection, it listens for the distinctive double-click of your resistance bands at full bat extension to measure exactly how long your swing stays on plane — then calculates your On-Plane Efficiency (OPE) percentage. HOW IT WORKS Mount your resistance bands, place your phone 3-5 feet from your swing path with the microphone facing up, and swing. ProVelocity's audio engine filters out background noise using a bandpass filter tuned to the click frequency range, then detects whether your bat produced a single click or the coveted double click — meaning your swing entered and exited the hitting zone on plane. ON-PLANE EFFICIENCY OPE is the core metric that separates good swings from great ones. ProVelocity calculates your theoretical swing time based on physics — your bat length, batter height, resistance load, and barrel mass — then compares it to your actual measured time in the zone. The result is a clear percentage score. Hit 80% or above and you're ready to increase resistance. Below that, the app tells you to dial it back and refine your mechanics. PROGRESSIVE RESISTANCE TRAINING ProVelocity is built around a simple feedback loop: swing, measure, adjust. When your efficiency climbs above 80%, add resistance. When it drops, reduce it. Over time, you build real bat speed through progressive overload while maintaining proper swing mechanics — not just swinging harder. EQUIPMENT PROFILES Pre-configured profiles for baseball, softball, and cricket bats. Select your bat length (30" to 33"), choose from 5 lb, 7.5 lb, 8.5 lb, or 15 lb resistance bands, enter your height, and the app calculates your expected swing speed and total swing radius automatically. SWING HISTORY Every swing is logged with date, speed, time in zone, and efficiency percentage. Track your progress over weeks and months of training. See exactly when your mechanics improved and how your efficiency trends over time. WAVEFORM VISUALIZATION After each swing, view a detailed audio waveform showing the decibel levels captured during your swing. See exactly where peaks were detected and understand what your swing sounded like to the algorithm. TUNABLE SENSITIVITY Training in a noisy cage? Quiet backyard? Adjust the decibel sensitivity threshold and click window timing to match your environment. ProVelocity works wherever you train.

Most youth sports tournaments don't have a scoreboard. Sideline Score is the one in your pocket. Built for parents on the sideline of football tournaments, baseball diamonds, basketball gyms, and soccer fields, Sideline Score is the fast, no-fuss way to keep score during your kid's game — so you stop doing math in your head and start watching them play. WHY PARENTS LOVE IT • One-tap scoring. The score is the biggest thing on screen, exactly the way it should be. • Configurable scoring rules per tournament — touchdown points, PATs, interception scoring, all dialed in once and then forgotten. • Save every game. Browse them later that night, or three months from now. • Personalized to your family. Your kids' names. Your team's colors. The app feels like it belongs to you. • Works offline. Sideline reception is unreliable; the app isn't. • No accounts to create. No ads. No tracking. SUPPORTED SPORTS • Football — Tackle, Flag, and 7-on-7 • Baseball, Softball, and Tee Ball • Basketball • Soccer • Lacrosse FREE TO TRY • 1 child, 1 team, 1 sport, up to 8 games • Curated team-color palette • Local-only storage on this device PREMIUM ($2.99, ONE-TIME PURCHASE) • Unlimited children, teams, and games • All sports unlocked, switchable any time • Full team color picker • iCloud sync across all your devices • Family Sharing supported YOUR DATA STAYS YOURS Sideline Score is a single-purpose tool. Your family's data lives on your device and, if you upgrade to Premium, syncs through your private iCloud account. We never see it. The only thing the app sends us is anonymous, privacy-first usage statistics — never your names, teams, opponents, or scores, and never anything that can identify you. Built for parents, by a parent. Made for the moment your kid scores and you want to remember it.
