This is an Interval or Circuit Lap Timer app to record lap times and calculate daily averages for groups of athletes, swimmers, cyclists, sprinters etc with an optional defined rest period between laps: the end of the rest period for an athlete is signalled to the coach by an audio-visual alert, even while the app is in the background. The coach can then advise the athlete to start the next lap and tap the appropriate start button when the athlete starts. This app has an interface for starting and stopping the athletes on an Apple Watch if present (iOS12.4+ and WatchOS4.3+). Setting the rest time to 0 enables split-time recording: each press of the Lap End button records the lap time but does not stop the timer. Tapping the Stop All button 'stops' all athletes but does not record a time. Press and hold the Lap End button to stop the lap and the timer. Total time is displayed in this mode. The app handles metric or imperial distances and optional pace calculations. All group members can be started at the same time or individually. Unlimited groups of athletes and athletes within each group are possible. Multiple groups can be on the go at the same time. The current day's lap times and averages for a group or an athlete's past lap times an be shared via email, SMS etc in CSV (comma-separated) format for easy loading into a spreadsheet program. The fifty most recent daily average lap times are shown alongside the current day's average lap time and lap information: lap time and optional pace - minutes per km or minutes per mile. Each athlete in each group can have a different lap length and a different recovery period - double-tap the athlete in the group list to modify the athlete’s lap length and recovery period. Notification of the completion of recovery period occurs even while this app is in the background. There is an optional 5, 10 or 15 second countdown timer when an athlete is due to restart to allow the athletes to be counted down to their restart. The total elapsed time can be refreshed in real time - there is a switch on the Settings screen. This option is not available when in Race Mode on iPad. There is an option to split athletes into two subgroups: those who have started and those who have stopped. The order of the athletes - if not split into two groups - can be rearranged. A 'Race Mode' feature on iPad provides a way to start multiple groups at the same time and/or start athletes individually, and then see them all and stop them as they finish. Started and stopped athletes are split into two groups for easier management. A CSV file with the names of a group's members can be imported into the app. Each line is a member's name, the file name must be the name of an existing empty group and have an extension of '.csv'. Eg: mail yourself the csv file and share it - this app should appear as one of the apps to which the file can be shared. A group can be cloned or deleted. REVIEWS Great For Sports Coaching - 4 stars Version 2.04 - Mar 8, 2016 (UK) [snip] Easy to use, accurate timing and an essential bit of kit if you need to time more than a couple of runners in training or races [snip] Lap timer - 5 stars Version 1.02 - Mar 14, 2013 (UK) Used this lap timer for a running session for a group of triathletes, we set up different rests for different athletes and set them all off. The app worked very well, last split available when they compete that lap. All their splits available at the end of the session. Will use again. App scrolls so you can add plenty of athletes. App does flash up the name of the athlete when their rest time is over.

This was a big selling feature for me and I was sad that it wasn’t functional. Additionally it would be nice to be able to see the cumulative lap data populate in real time for very short intervals instead of after the timer is stopped. **Developer response:** For the 'share' issue: only data for 'today' is exported from the main screen so if there is no data 'today' then no data will be exported. Past data can be shared from the screen showing each day's laps. Please ensure Mail is configured on your device (iOS stopped showing alerts when Mail is not configured). Please install version 2.08.01 which introduces a new switch that enables the display of real-time cumulative lap data. As with any app, if there are any issues or suggestions please contact the developer via the developer link on the App Store. ### 4/5 — Great For Sports Coaching *2016-03-07, version 2.04* I'm a running coach and have been looking for an app to time multiple persons doing lap times at different speeds and intervals. The latest version now gives the option of a warning period (5-20 secs) when an interval for a runner is coming to an end, has race mode, option to move runners up or down the group list (making it easier to keep track of who is expected to complete the next lap first), the ability to create groups by cloning them and a link to instructions. It shows lap times, average daily lap times and the ability to email results. Easy to use, accurate timing and an essential bit of kit if you need to time more than a couple of runners in training or races. Great for handicap races - you can group runners and start them at the same time per group! Used with 8 runners so far on lap intervals - no problems. ### 5/5 — Great multi-timer for any application *2013-04-22* I am not a trainer but I use this app to keep track of multiple sampling sites for agricultural field testing. The multiple timers allow me to record the time between samples taken at different places in the field multiple times a day with a single tap, and the CSV export allows me to easily get the data into excel for further processing. No more clip boards and sheets of paper flapping in the wind! It’s so easy to use. Definitely recommend for anyone needing to record the time or duration of multiple repeated events, in any application! ### 5/5 — Lap timer *2013-03-14, version 1.02* Used this lap timer for a running session for a group of triathletes, we set up different rests for different athletes and set them all off. The app worked very well, last split available when they compete that lap. All their splits available at the end of the session. Will use again. App scrolls so you can add plenty of athletes. App does flash up the name of the athlete when their rest time is over. ## Frequently asked questions about Circuit Lap Timer ### What is Circuit Lap Timer used for?
