HIITList

Management summary : Extract sprint intervals from GPS tracks or HealthKit workouts - automatically. Forget these start-stop-lap buttons. More details : You are a sprinter. Your trainings? Intervals. High intensity. 12*60 meters - 8*300... . Pushing a stopwatch button or waking your phone slows you down, so you don't. Comes HIITList : just power your watch and HIIT. When finished, just let HIITList do the analysis. (Note : from version 2.0 on, you can use your iOs device to record your training. Continued use of GPS running in the background can dramatically decrease battery life.) Features : - Define the intervals you want to track : 60m, 120m, 150m, 300m... . Minimum start speed (to avoid flying starts screwing up your sprints), minimum elevation, minimum speed for an interval to be considered etc... . - Import tcx/gpx files from iCloud drive, internet or eMail attachments. HIITlist scans them and detects the intervals. - Or you can record your trainings using your iOs device. - View performances by training or by interval. - Interactive Graphs and maps. Warnings : - This version was tested with GPS devices that use one second recording. Tracks registered using smart recording might produce faulty results. Support will come in a later release. - HIITList uses GPS coordinates. Indoor workouts are NOT supported. - Currently, HIITList is metric only (athletics tracks are metric, so are Olympic distances. Not sure if there is demand for miles. But we'll add it at users request). - Speed is expressed in km/hr, not min/km. (Again, we'll add if upon user request). - You'll need a GPS device with a barometric altimeter to differentiate between flat tracks and hills. Define your intervals with a large enough (+10mr) maximum ascent and descent for devices without barometers. - GPS devices have an error margin of a few meters. And one second recording means your start will be missed by up to half a second. So do not expect spot-on times. For reference : a 100 meter race electronically timed at 13:68 was estimated at 13:76 by HIITList. A 200 meter race electronically timed at 27:38 was HIITListed at 26:83. All these races were run with a Garmin ForeRunner 610. You can find some examples on https://hiitlistapp.wordpress.com/.
