Interval training timer for CrossFit, HIIT, Bootcamp, MMA, Boxing, and Circuits

Say hello to the future of interval training timers! The GymNext Flex Timer is the world's first interval training timer app that also controls a wall mounted LED display. It's great for interval training workouts like CrossFit, HIIT, Bootcamps, Intensity, MMA, boxing, and many others. While traditional wall-mounted LED timers provide a great, easy to see display, they are plagued by difficult to use remotes that are easily broken or lost. Alternatively, smartphone timer apps provide a much simpler, more powerful approach to control and setup, but the in-app display is difficult to see from around the gym. Enter the Flex Timer - the best of both worlds! Combining a highly visible LED display that can be seen from all over your gym with the most advanced, easiest to use interval timer app available. You're going to love it! Check out these great features: * use the app standalone without an LED display or combine it with our Home or Gym Edition timers and you'll never squint to see the time remaining again * 11 highly customizable timer modes including Standard, Round, Interval, Tabata, EMOM, Sets with Rest, Stopwatch, Multi-Segment, Shot Clock, Scoreboard and Beep Test to cover virtually any workout you can think of * save your favorite workouts for instant recall in the future * go hands-free with Android Gear to control the timer from your wrist * use Chrome Cast to display the timer on a television screen or monitor * hook up your bluetooth heart rate monitor and you can track your heart rate as you workout or setup zones to let you know whether your pace is appropriate * connect to multiple clocks around your gym and simultaneously control all of them or hook up to them individually and run separate classes * run multiple different timers at the same time * with bluetooth control, you can now start, stop and pause your timer from acute angles and around corners - no more line of sight restrictions High Praise for the GymNext Flex Timer: "This will eventually become the standard for all gyms" - Garage Gym Reviews "All our coaches love the clock" - CrossFit Barrie "We got the Gym Edition and we love it to death" - Wolverine Strength & Conditioning Download the app and try it out for yourself. You won't be disappointed. You can purchase a GymNext Flex Timer LED display at http://www.gymnext.com or on Amazon.com. -- We love to hear from our users so that we can build the features you want.
