5 out of 5 stars

Nice timer but……
First off this timer is very nice. Works from an app on your phone and is easy to use. I like it but had to get a replacement on the first one because shipping was so crappy that the box was open and things were missing. Beside that it is a nice timer and I would recommend it. The cord is only 5 ft and way too short so I ordered a longer extension for it .

Thank you for your feedback

    We love our gym timer. It works great. The app is very easy to set the workout of your choice. I highly recommend this product.

    This timer is everything and more. Features that I love: 1) integration of Bluetooth to pair with your phone, 2) Simple platform that is easily programmed from your mobile device, 3) Display and sound is very clear and crisp, 4) It allows for use of an HR monitor, 5) Your ability to play music from other apps while using the timer, 5) The quality of the timer build and how it was designed, 6) Customization settings that allow you to program your timer the way you want. If you are looking for more structure to your workout, this is it. Although one of the more pricey options, it is well worth the investment. Pull the trigger, it is worth the investment and wait. I purchased a used one on here and it came quickly. The brand new option was back ordered and was mot going to arrive on time (I waited a month to no avail).

    Reliable and helpful in my home gym. The interaction with bluetooth is fiddly but once you’ve set it up and your timer is counting, it’s reliable and works well. If you’re connecting its audio to a separate bluetooth speaker playing your ipod songs, it can lower the volume of the song to send its own audio of a male or female voice that counts down the start and tells you your workout is done, then the song resumes its regular volume. Sometimes this process doesn’t work right and the song volume stays low. The app is starting to advertise other products, in the app itself, which is annoying, and I hope they stop this practice. Don’t sell to me while I’m using your app that I paid for! Just don’t. Overall, the product works well for timing your workouts and getting jacked. I wouldn’t purchase another one if they continue to advertise to me.

    The device has great potential and worked great. Once I hit the year mark, the timer just died and constantly beeps and and flashes on 12:00. It won't connect any more and just beeps and flashes. So great while it lasted but not worth the price to last a year. I would not recommend this device

    EDIT** it's now a a bit of time later since my post. I got in contact with customer service with 24 hours. They were very respectful and fast. They made sure the device problem was resolved and addressed. It has been working great since they sent their resolve out for a part. I am very pleased with this.

    I was really excited about getting this clock for my home gym. I used it one time and left it unplugged after use. My phone disconnected a couple of times while I was using it. I ordered the extension cord and plugged it back in after mounting and now it won’t turn on. I requested a return and refund through Amazon and may order another and give it a second chance. I really like the clock and ease of use with the app but I am a little unhappy with only getting one use.

    Edit:

    Second one has been working great. Updated the firmware out of the box and there’s been no issues! Great clock.

    $150 is a lot for a timer. There are cheaper alternatives if you need a budget solution. That said, if you're building a serious home gym, this is worth the premium price. You're going to spend way more on equipment than on your timer. And how you relate to and manage time during your workout is important.
    The build quality is excellent. It connects to iphone instantly and reliably. The app has many features and settings that can be adjusted. I like that it includes a "prelude" option so that you can click start and still have time to set up before beginning your set. I do think the app could benefit from a cosmetic upgrade.

    It's cool that you can connect an Apple watch or heart rate monitor. It will display it on screen for you. However, if you also want to track your HR in a separate app, the timer loses access to the HR data. It's annoying but there's nothing they can do about it as it's an iphone limitation. Overall, I'm happy with the purchase.

    This is amazing and well worth the money. I was previously using my phone or laptop for a timer, and wanted something more official and that reminded me of a real gym (in my home gym). The app is super intuitive and I love you can “favorite” different timers for easy future access. The beeping on this thing is super loud and there’s no way to adjust the volume (from what I’ve found). It’s great if you have music or other noises going on, but may be too loud for super early morning or late night workouts (for your neighbors if you live in an apartment complex like me). The app works as a standalone timer as well if you travel. Super stoked to use it for my next workouts!

    This timer is AWESOME! Love that pairs to my phone and it does so super easily and quickly. The ability to create timers in almost any configuration is the best thing about this device – you can share the timer with others and never have to worry about someone overwriting your preferred timers. Another BIG win for this unit is the volume – even without it being connected to a speaker you can hear the 85db speaker clear across the room, with radios and people at volume, too. Can't say enough good things about this timer – well worth the extra money you'll spend over the others on Amazon, some with larger displays but without the volume or flexibility. BUY THIS TIMER – you won't regret it.

    At first it was great: Very clear, the app had numerous settings and options and perfect for the home gym or even a gym . However, the app has stopped connecting with the timer. I have done all the trouble shooting options multiple times: permissions, blue tooth, location, factory reset, re-installed etc. Even tried 2 different phones – Still will not connect. I really can't be bothered to waste anymore time (no pun intended) on this. The return window expired 16 months ago and they are out of stock. Very poor and would not buy again anyway. One for the scrap heap!

    Chi usa questi timer da palestra, sa l'odio nel settarli col telecomando…
    Questo si setta in un attimo tramite l'app, ha anche dei timer già preimpostati.
    Se il telefono è collegato alle casse, gestirà anche gli audio del countdown e la musica, volendo si può anche "proiettare" su un monitor esterno tramite mirroring.
    Il costo è un po' più alto di altri prodotti, ma secondo me li vale tutti
