Sprint Lab - Sprinter Tracker

"Sprint Lab" is a training management and time measurement app designed specifically for track and field athletes competing in sprints like the 100m, 200m, and 400m. From daily workout menus to video-based form checks, detailed times for start dashes (SD) and flying sprints, and meet results, you can centralize all the data a sprinter needs. [Key Features] ◆ Slow-Motion Video Playback & Time Measurement Equipped with video analysis tools essential for checking your running form. You can play imported videos in slow motion or frame-by-frame, and measure split times directly on the video. This powerfully backs up your practical analysis on the track, helping you check ground contact time, stride frequency, and practice times. ◆ Track & Field-Specific Calendar & Training Log Record your training menus using sprint-specific categories like "Start/Acceleration," "Max Speed," and "Lactic Acid Tolerance." You can also easily input your daily condition (on a 5-point scale) and training intensity (%). ◆ Target Times Calculated from Your Goals By working backward from your goal times for the 100m or 200m, the app calculates and displays the "target times" you should aim for in your daily workouts. Having a clear pace metric creates a positive tension in your daily training and supports rigorous reflection. ◆ Radar Chart & A-F Rank Evaluation Visualize 6 different abilities—such as "Start," "Max Speed," and "Strength"—on a radar chart based on your 30m SD, flying sprints, and weight training results. It evaluates your current ability level against your set goal time using an "A to F" ranking system, allowing you to objectively grasp exactly what you are currently missing. ◆ Meet Results & Wind Speed Logging Record official times along with the wind speed (+ / -). You can also register upcoming meets (including their importance level and target times), making it incredibly smooth to manage your peaking schedule for crucial races. ◆ AI Coach Data Analysis (Daily & Weekly Reports) The AI comprehensively analyzes your inputted training content, intensity, fatigue level, and upcoming meets! It provides personalized feedback and advice, such as, "Your intensity dropped today, but it's perfect for tapering ahead of this weekend's meet," or "Since you've had consecutive high-intensity days, active rest is recommended for tomorrow." ◆ Time Prediction Tool Includes a tool to predict your 400m finish time based on your 200m or 300m split times. [Message from the Developer] "What specific training do I really need right now?" "Is there a disconnect between how my run felt and the actual time or video?" I developed "Sprint Lab" to solve these exact struggles faced by track and field athletes on the ground. Through daily coaching and facing my own training, I've packed this app with every feature I "truly wanted." I hope it becomes a trusted partner on the track for every sprinter aiming to crush their personal bests!
