Flex Timer

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
* eight highly customizable timer modes including Standard, Round, Interval, Tabata, EMOM, Stopwatch, Shot Clock 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 or Pebble to control the timer from your wrist
* 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 timer 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"

"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.

Love it! I found lots of HIIT timers, and countdown timers which weren't really what I wanted. Then I found this and it had exactly what I needed which was the EMOM (every minute on the minute). It's even better than I hoped as I can use the round timer to adjust the intervals between rounds - it's super flexible! I haven't used the heart rate features but will do at some point. And there are timers for pretty much every sport you could ever need to time. Excellent app!

It was hard hard to use when we first got it. Then it was a breeze to set up. NOW IT IS HORRIBLE! Whatever update the app received a few weeks ago made setting up my workouts in accessable. For example, if I wanted 10 rounds of HIIT, the first 3 rounds at 45s, the next 3 rounds at 30s, and the remaining at 60s.....I cannot do it anymore. I was able to before this update. Now I have to stop and set up and use a different timer EVERYTIME. The multi segment doesn't work. Who designs this app¿

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).

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.

Everything was going great until whatever update or "fix" the app has undergone recently. Now I'll be over halfway through with a workout and the timer will just shut itself off. Please fix this, it was such an amazing app until this happened. I can't play music anymore because it will just shut itself off.

I love it, and use it quite often for interval/circuit training. I wish it had a pyramid setting that I wouldn't have to enter every interval at a different time, making it a bit more time consuming. Also would be nice to save favorites when you finish a workout you intend to repeat.

Nub. C. Jun 30, 2019     

Look no further. Seriously this is easy to use and it works well. I use it mostly for boxing and ab routines with occasional hiit and tabata. I've used for so long (1 year+) and I plan to keep using it. (fyi I use while I'm listening to music and it integrates well with that) Kudos to the creator of this app for making something so useful to people.

Sam. E. Oct 1, 2019     

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.

Jen. May 4, 2022     

Great features but creating custom timers is really confusing. Sometimes changes will save and sometimes they won't. I still can't figure out why. Not intuitively designed.

Tay. L. Mar 23, 2020     

This app is perfect. I can set up any type of workout very easily. Any type of workout! Tabata, EMOM, circuit rounds, with or without rest periods. And it doesn't have to be open to use it, so I can mess around with my music apps while using it.

Jos. S. Apr 16, 2021     

The app's connection with the physical timer is terrible. Each day I go to use the timer, I have to force stop the app and then restart my phone. Otherwise, it will never find the timer. When they do connect, it is great. But having to restart my phone in order for the app to work is absurd.

Nik. S. Jul 7, 2020     

It's good, but interface could be better, it's not very intuitive and the app is a bit buggy at times. I like that you can customize all the timers and save them for different workout routines. It's a big help for all my workouts!

Tra. L. Jun 6, 2020     

Works Great!! Just a little difficult to figure out in the beginning with how to truly set up the timer for the rounds and rests. Other than that one toy get it, it works phenomenally. Great download and easier to use than others. Try it for sure.😁

Sha. C. Sep 14, 2019     

Has been working great until lately. All of the sudden it keeps shutting down if I try and edit a favorite timer. One suggestion is to be able to adjust the order of favorites timers. I'd prefer them to be alphabetized or allow us to reorder them on our own.

Mab. S. Dec 26, 2018     

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

Ran. E. Sep 30, 2020     

I will have to retract my previous review on this app. The app crashes on me consistently now and I'm not about to complete one full circuit of my workout without having to get up and restart my timer. It will say 'go' but will never countdown to the next round; it just crashes. 2 stars and I am getting a new gym timer app.

Fir. L. Jul 29, 2020     

Stand alone app = 5 * Actual timer = 5 * The connection between the 2? Zero * ALWAYS loses connection (Not during use, After the timer is closed). And is absurd to try and reconnect. Update: dev emailed me that link. It's for S10 phones. I don't have an S10. The issue is with disconnecting or closing the timer. Every time I try and reconnect I have to unplug the timer 6 times, force close, clear caches, and cross my fingers, etc. Waste a bunch of time and ultimately won't connect anyways.

Dan. V. Aug 4, 2020     

The audio beeps interrupt music. You can either turn them all off or all on but you can't select which ones to keep (for example keep start and stop round but not the countdown). No way to prevent them from interrupting music playing in other apps.

Ste. S. Jun 1, 2020     

Nice flexible timer! There is an issue with Bluetooth connectivity and my Samsung Galaxy Note10+. The problem is with the phone and not the app, so can't fault Flex Timer for that. Clearing the Bluetooth cache fixes the issue, but it's kind of irritating.

Mad. M. Apr 20, 2021     

This timer has seen me through a rough year. It's intuitive, flexible and easy to figure out. It has a BIG timer and talks back to you. I use it 5+ times a week. The only addition I world make is the ability to label an interval. Thanks dev!

Ale. E. Feb 13, 2020     

If you're looking to waste your time, then this is the app for you. I spent 1.5hrs creating a few interval trainings, and saved them to my favorites once completed. Next morning when I went to workout, they were all gone! Complete waste of time. Do not use

kal. p. Jul 28, 2020     

Best timer app ever. So many options to help me use my phone ALOT less during work outs and get through them alot quicker. I don't have the clock to connect to but I use my blue tooth head phones and there's a narrator counting down and stuff . Love the app so far.

Cy. Sep 27, 2020     

I wanted an app that would continually clock 30 seconds on it's on (intervals). This app not only allows for that, but you can customize the intervals to run through sets as well. It's great.

Fel. O. Jun 5, 2020     

The Emom timer keeps beeping three seconds before each round, I've disabled it a thousand times, changed it, erased and and re set the timer again... I want one beep every minute, not three. At the same time those three beeps add to the minute instead of being part of the minute so you do one minute and three seconds (of beeps) each round, what makes it impossible to coordinate with external timers.

Mar. M. May 20, 2020     

This is an awesome timer. I do a nice 12 round chest blast routine I found online. I set round internal and rest in between. I really like that the Flex Timer has a countdown before each round, and it's audible. You can also save a favorite routine. Cool app, 5 stars!
