Send a planned workout from iPhone, then progress through warm-up, reps, recovery, components and cool down on Apple Watch. Enter manual times, use Ready Now or Hold, and review completed reps without reaching for your phone.

Timing

Capture what happened. Keep the best result.

MaxSprint supports manual result entry, audio-cued timing and Freelap capture. If a more precise electronic result arrives after a provisional time, MaxSprint can use it for the final workout record.

01

Manual

Enter a rep time on iPhone or Apple Watch when hand timing is the right fit.

02

Audio cue

Run supported workouts against planned cues while preserving targets and rep structure.

03

Freelap

Capture compatible Freelap timing data and splits inside the workout workflow.

Freelap is a third-party timing system. No partnership, affiliation or endorsement is implied.

Capture + Analyse

Compare like with like.

Review rep times, splits, target adherence and completed volume. MaxSprint separates starts, flying sprints, training efforts and race performances so unlike results are not silently treated as the same test.

Training intelligence

Context for today, grounded in your sprint history.

With permission, MaxSprint can combine sleep, morning resting heart rate and HRV with an optional questionnaire, recent training load and sprint-specific history.

  • TodayReview recovery markers alongside completed and planned work.
  • Decision supportOpen the scheduled session, build training, or reconsider quality work when context is suppressed.
  • DescriptiveLook for repeated patterns rather than treating one score as a verdict.

Training information only. MaxSprint does not diagnose injury, illness or readiness to participate.
