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.

This has to be the best app you can use to set up your workouts Whether its cardio, calestenics, or weight lifting, it can seriously help you. Especially for people like me who have a hard time remembering their workouts.

I've used this app for years and I really like it. But, since I upgraded to Android 14, this app will not work at all. I have had to find an alternate app as I am a fitness instructor. Hoping and waiting for a fix to whatever bug was caused by this android upgrade. I'm having similar issues with other apps on this android version. I use a google Pixel 6 phone.

Very buggy. Not very intuitive to use. If you make changes to a timer and don't remove the star icon and reset the favorite you will lose all your changes. Sometimes my timer starts from the wrong side when I'm doing multi-segment until I reboot the tablet and clock. The workout shouldnt move to the timer screen unless I explicitly move it. Having said that I LOVE the idea of this app with the timer but it's too buggy for me to give it a 3. A few app fixes and it could easily jump to a 4.

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.

Works great, many great features. Super convenient with the phone. This timer is suited to someone who wants more details out of their workout, or just someone who wants the convenience of using their phone, not a remote and the power and flexibility of software and an app that can customize multiple settings and save all your scenarios for future use. You might be able to do some of that with a remote, but it would be cumbersome and require a manual. The timer build quality itself is excellent.

Easy to use but the signals don't go off when the phone is locked. Unless I press a button on my phone, I don't know where I am in my workout. I blew through several rests before I realized what was happening. Fix that and this would be a 5* app. I really like this but will uninstall if no feedback can be provided on this... Thx.

Love almost everything about it other than there is not a way to turn down the voice cueing without completely turning it off. If you connect the timer/app via Bluetooth to a stereo along with music the beeping and voice is much louder then the music itself (obnoxiously). I have received complaints from neighboring businesses due to the beep and voice (not music).
