Ok but not working 100%
Response from developer
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.
Great For Sports Coaching
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.
