Calculator For Runner (CalcForRun) vs Multi

This is a calculator that allows all runners to simply calculate their lap-time and pace. It feels the same to use as a typical calculator, but it can also carry out for different operations for calculating time. Furthermore, it also has a special screen used to calculate a runner's pace prepared below. - Judging by the distance(km or miles) traveled and time elapsed, the calculator can determine the pace and speed of a runner. - Judging by the pace (or speed) and distance(km or miles) traveled by a runner, the calculator can determine the time elapsed. - Judging by the pace (or speed) and time elapsed, the calculator can determine the distance(km or miles) traveled. ----- Ver2.2 Update ----- - Track mode has now been added to split time tables On occasions where distance equals 800m(0.8km)/1000m(1km)/1500m(1.5km)/2000m(2km)/5000m(5km)/10000m(10km), split time tables can now be displayed on the basis of track distance, instead of 1km intervals. - A search function has been added for crossing times at cheering points A mode has been added to estimate cheer point crossing times, calculated from estimated finish times or crossing times for the preceding lap point. Calculate from estimated finishing time / Calculate from crossing time for preceding checkpoint ----- Ver2.0 Update ----- The calculator is compatible with four inch displays and the iOS7 screen. The user can change the settings from full-marathon, half-marathon, or a user-determined distance with only one touch. The user can insert seconds, minutes or hours into the time display. The pace calculating screen can also be used to show split-times. Using the backspace button, the user can return to their entries prior to their current one. ----- Calculation Rule ----- Measuring time requires choosing seconds, minutes or hours as the lowest unit of calculation. The numerical value of time for addition will be calculated using seconds. In the case that numerical values are subtracted from time, calculations will be done using seconds. Numerical values cannot be subtracted from time. When the numerical value is divided by time, speed is calculated. The multiplication of numbers and time will become time. However, in the case that the previous calculation's result was speed, the numerical value of distance shall be calculated. Time cannot be multiplied by Time.

All basic features are available for free! Perfect for coaches, athletes, and anyone who needs to measure multiple times simultaneously! As a runner myself, I created this app from the perspective of athletes and team managers who want precise and flexible timing tools. A multi stopwatch and interval timer for team managers, race timing, training, games, business time tracking, and anyone who needs to time multiple people or events at once. Built for track & field, swimming, cycling, motorsport, fitness training, games, work-from-home billing, and everyday timing. Record lap and split times, manage multiple stopwatches, save results, and review past sessions in the calendar. ■Stopwatch Features Run 20+ stopwatches simultaneously (device-dependent) Record lap and split times for multiple people or lanes Save and review data with a built-in calendar view Copy or export timing results for Excel and Google Sheets No-look lap timing for fast-moving races where you cannot keep watching the screen Useful for track & field, swimming, cycling, motorsport timing, games, events, and business workflows ■Video-Synced Timing (Premium Feature) Sync stopwatch time with video playback: slow motion, fast-forward, or pause Measure finishes and lap times more accurately Review sprint finishes, swimming touches, race moments, or close results frame by frame Easily record multiple athletes' lap times by pausing the video and logging times ■Interval Timer Supports up to 99 repeats and 5 customizable intervals Set sound alerts, vibration, and background operation Perfect for Tabata, HIIT, circuit training, study sessions, cooking, and daily routines ■Recommended For Track & field coaches and team managers Swimming coaches and lane timers Runners, swimmers, cyclists, and athletes PE teachers and fitness trainers Cycling, motorsport, keirin, and other race timing Games, events, billing, business tasks, and any situation that needs multiple timers How to Use Switching Modes: Swipe horizontally to toggle between Stopwatch and Timer. ■Stopwatch Tap START, STOP, LAP, or RESET as needed Save data via the bottom-left data icon -> Save -> add a title Tap the stopwatch screen to rename players or lanes View saved data: tap Data -> Calendar -> select a marked day -> choose a title and name ■Timer Add up to 5 intervals by tapping the "+" button Set repeat count by tapping the repeat icon Tap the sound icon to toggle sound or vibration Countdown begins automatically when the timer starts Reset any time with the RESET button Sound Effects: Courtesy of OtoLogic
