- Swim Pace CalculatorCalculate swim pace per 100 m or 100 yd, speed and projected time.Open calculator
- Swim Stroke Rate CalculatorCalculate strokes per minute from a counted stroke interval in the pool.Open calculator
- Swim Distance per Stroke CalculatorCalculate average distance per counted stroke and strokes per pool length.Open calculator
- Swim Split PlannerGenerate cumulative and interval splits for a target swim using any entered course length and checkpoint interval.Open calculator
- Swim Race Split Analysis CalculatorAnalyse ordered cumulative swim checkpoints, segment pace, fastest and slowest segments, variability and first-versus-second-half balance.Open calculator
- Swim Set & Send-Off CalculatorReconcile repeat count, swim time, send-off, between-repeat rest, final arrival and complete set duration.Open calculator
- Swim Workout Distance & Time CalculatorTotal labelled swim blocks into session distance, active swimming time, rest time, repetitions and average active pace.Open calculator
- Swim Repeat Set CalculatorSolve a repeated swim set's work distance, active time, between-repeat recovery, total duration and average work pace.Open calculator
- SWOLF CalculatorCalculate the conventional per-length SWOLF sum while retaining length time, stroke count, pace and distance-per-stroke as separate measurements.Open calculator
- Critical Swim Speed CalculatorCalculate a transparent two-trial critical-swimming-speed line from entered longer and shorter maximal efforts without generating training zones.Open calculator
- Swim Stroke Index CalculatorCalculate average velocity, distance per complete stroke cycle and stroke index from one consistently measured surface-swimming segment.Open calculator
- Swim Stroke Metrics Reconciliation CalculatorReconcile average velocity, complete-cycle rate, cycle length and elapsed time from a measured segment and counted cycles.Open calculator
- Pool Length, Lengths & Distance CalculatorConvert a measured pool length and completed lengths into total distance, round-trip equivalents and any partial final length.Open calculator
- Swim Performance Comparison CalculatorCompare two recorded swims by time, distance, pace and speed without extrapolating either result into a prediction.Open calculator
- Target Swim Time CalculatorReverse-solve target finish time, pace, speed and proportional quarter checkpoints from entered distance and pace per 100.Open calculator
- Swim Pace Band CalculatorApply a visitor-entered faster and slower margin around a reference swim pace and show the resulting per-100 and projected times.Open calculator
- Swim Set Comparison CalculatorCompare two swim sets by total distance, active time, rest time, session time, active pace and work density.Open calculator
- Swim Session Density CalculatorCalculate active-swimming share, rest share, distance per session minute and average active pace from an entered session record.Open calculator
- Swim Pace Decay CalculatorMeasure first-to-last pace change, fastest and slowest repetition, mean, population variability and total active time across ordered repeats.Open calculator
- Swim Start, Turn & Surface-Time CalculatorReconcile total race time into entered start, turn, underwater and surface-swimming time with explicit shares and residual checks.Open calculator
- Swim Underwater Segment CalculatorCalculate underwater distance and time shares, underwater speed and remaining surface distance and time from measured race segments.Open calculator
- Swim Relay Split CalculatorTotal labelled relay legs, compare each split with the team mean and report fastest, slowest and spread without selecting a lineup.Open calculator
- Swim Time-Standard Gap CalculatorCompare an entered performance with a visitor-entered event standard and report signed time, pace and percentage gaps.Open calculator
- Open-Water Loop & Distance PlannerCalculate complete loops, partial final loop, total course distance and estimated elapsed time from an entered measured loop and pace.Open calculator
- Open-Water Current Scenario CalculatorCompare still-water speed with an explicitly entered aligned assisting or opposing current component as a bounded mathematical scenario.Open calculator
