About this app

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

Works great for me. Very flexible. If I don't find what I want in a preset, a lot of times, I can find it in another preset. The one thing that would be really great to see if it could voice out the interval name. I have a separate app that I use for stretching. It will read the Name of the interval. Eg. Prepare for Bridges. Prepare for swimmers.

I LOVE THIS!!! Everything I was looking for in a gym timer, and then some. First and foremost, I like that the sound is played thru headphones rather than the phone speakers which is just plain rude to other people in the gym. And, you have the option of hearing verbal cues (from possibly the coolest guy on this planet) to tell you when to start, stop and rest. You have the option to use a timer beeping sound instead if you prefer that, but why would you lol Easy to use ... 5 Stars

Great garage gym timer, great interface with the app. Only downside is it'll error and not show what's on the app. It's annoying when it happens, but it's not very common. And, you can never lose the remote. Had the large timer donated to our CF gym in Kuwait (Crossfit Spartan Shield) it was a huge improvement from what we had before. That's what made me want one in my garage gym. Best timer on the market. I also rely like the ease of use on the app and all the different functions.
