Simple Sprint Timer vs MaxSprint

I originally built this app for my wife, and wanted to share it in case anyone else finds it useful. It's still in very early beta — expect rough edges, and feel free to reach out with feedback. I've released the source code for free on GitHub in case anyone wants to tinker with it: https://github.com/jasonnmark/SprintTimer

MaxSprint is a sprint training platform for athletes who want to plan, execute and analyse speed training in one place. Built for sprint performance, MaxSprint combines workout building, individualised targets, Apple Watch, timing-gate compatibility, optional cloud sync, coach connectivity, readiness monitoring and sprint analysis. BUILD SPRINT WORKOUTS Create sessions for acceleration, maximum velocity, speed endurance, special endurance and more. Build workouts using: • Standard repetitions • Split and broken runs • Variable-distance and ladder sessions • Timed or walk-back recoveries Target times can be individualised using your sprint profile, training intensity and session demands. INTELLIGENT AUDIO PACING Use audio pacing to help control rep intensity without constantly checking a stopwatch. MaxSprint can pace around different phases of a sprint rather than simply dividing a target time into equal splits. TRAIN WITH APPLE WATCH Run guided sprint workouts from Apple Watch with rep progression, recovery timing and key workout information on your wrist. Planned workouts can also be delivered to Apple Watch and completed independently. You can also train directly from iPhone. TIMING GATE COMPATIBILITY Compatible timing data can be captured during live workouts and automatically added to your session. View results during training, compare performances against targets and retain data for later analysis. MaxSprint is not affiliated with or endorsed by Freelap. CONNECT WITH YOUR COACH Create an optional MaxSprint Cloud account to connect with MaxSprint Coach. Receive planned workouts, share completed training and keep workout information synchronised across supported devices. Cloud functionality is optional for individual training. PLAN AND TRACK TRAINING Work from planned sessions while preserving the difference between what was prescribed and what was completed. Review delivered volume, sprint-quality exposure and performance over time. MONITOR TRAINING READINESS With your permission, MaxSprint can use relevant Apple Health data together with training history to provide a personalised readiness assessment. Depending on available data, this may consider: • Sleep duration • Resting heart rate • Heart rate variability • Recent training volume and intensity • Sprint performance • Optional questionnaire responses • Optional countermovement jump results Readiness information is for training and informational purposes only and is not medical advice. ANALYSE YOUR TRAINING Review: • Individual repetition performance • Fastest and slowest repetitions • Split times • Target versus actual performance • Training history • Planned versus completed training • Sprint-quality exposure • Performance trends BUILD YOUR SPRINT PROFILE Create an athlete profile using your performances and training data. Track sprint times and use your current ability to guide training targets. PRIVACY-FOCUSED BY DESIGN MaxSprint does not sell your personal information, use it for third-party advertising or share it with data brokers. HealthKit access is optional and controlled through Apple's permission system. If you create a MaxSprint Cloud account or connect with a coach, selected account, athlete profile, planning and training information may be securely transmitted and stored to provide cloud synchronisation and connected features. SPRINT TRAINING, IN ONE PLACE Build the session. Train with purpose. Capture your performance. Understand your readiness. Analyse the result.
