OnUrMark is a seamlessly integrated timer & data management tool which will revolutionize the way training times are made and stored for runners, swimmers, cyclists and any coach looking to log their athletes. The unique design, utilizing volume buttons to mimic a stopwatch, allows anyone to accurately time multiple runners, cyclists, swimmers or anything moving, then easily store and export the data. Simply put, it allows the user to focus on the athletes and not what they’re supposed to be hitting on the screen. This removes the need for professional athletes, coaches and trainers to use multiple time keepers and inconvenient training books, and also gives the public at large the ability to easily record races and save their data.
