  • Excellent Tool for Improving Breath-hold Jan 4, 2019

    By Mr3-D
    I’m just beginning to train for free-diving, and this app has already helped me double my breath-hold time. I especially like using the CO2 exercise table, and the fact that the app automatically updates my settings when I use the built-in stopwatch to set my new records. Doing these tables everyday will definitely help you improve your static dry apnea times.
  • Gets the job done, but worth the $??? Feb 5, 2018

    By Chi Chi Gonzales
    UPDATE: timer is now defaulting to 23:05:00 vs 00:05:00 as the developer has indicated is the default below. No response to emails sent with screenshots of such. While it’s a minor issue, there’s simply no need for a timer to even go to these ranges. A better setup would be to emulate that of the recent change to iOS where a user can set hours, minutes, and seconds. First, I don’t free dive but needed something that would give me focused breath control practice. This app is pretty simple but gets the job done. For my purpose, at least. I use it for a guided relaxation breathing practice because I’m lousy about doing it on my own. It does have a couple quirks: 1. The timer isn’t labeled so you have no idea that the left number is HOURS and the right is MINUTES. And for some reason, it defaults to 17:05:00. 17 HOURS!?!?!? 2. The instructions for the app are lacking and some of the App Preferences (AM/PM time) have no explanation of what they do so you have to toggle them on/off and “search” for what change took place. Overall, don’t know that’s its worth $2.99 though.
  • Worth Every Penny Jun 5, 2018

    By Fesslertime
    It’s a quality app! They could probably ask for a higher price; I have to say it’s worth every penny because they’re only asking for pennies! I tried to save money by using free breathing exercise apps before this, and they were much more frustrating. This doesn’t lock you out, give quality workout instructions, and looks great!

    I loved it first I kept doing the hold your breath port and I got 20 seconds and I felt like I was going to die then I stared doing practice and I got 27 seconds and it was so easy and I didn't feel like I was going to die.
  • Highly recommended Jun 30, 2018

    I just started diving recently and have researched a lot of different tools for apnea training. This app has been amazing! Super easy to use and multiple options for training types. Happy spearfishing all!!
  • Excellent App Sep 20, 2017

    By Dstover717
    I bought this app to help with my physical performance. It is great to use as a timer for the breathing protocols. I believe I originally heard it mentioned by Tim Ferriss or Gabby Reese in a podcast or interview. It does everything I need it to.

    I’ve had this app for many years and it still does what it’s supposed to do. No bloat, ads, gimmicks, etc. Thanks for a great product.
  • Easy effective Apr 11, 2018

    By SkyT14
    An easy way to keep cadence with breathing and focus on the breath instead of timing. I love it and use it daily.
  • I use it for meditation Jan 26, 2019

    By Dxhfvkugktwm
    Really helps me focus on my breath. Clears my mind. And the app has become much nicer over the years

    I used this app on iOS and loved it. But the Android version has a fatal flaw. It doesn't prevent the display from going to sleep and when I unlock my phone, the timer is stopped and can't be restarted. I can't even make it through 2 cycles.

    I completed in app purchase to create a custom breathing pattern and it doesn't work. Always goes back to the default Apnea ratio. I paid $7 for nothing. Please refund
  • Why does the clock stop in the background? Nov 10, 2018

    By AKM06
    Really great app... besides the fact that I have to stare at your app to keep the clock running instead of it speaking to me in the background while I’m watching a relaxing dive video.
  • Offers very minimal training. Sep 30, 2019

    By wildwilderness
    Unsatisfied with this product. It does very little to create an effective training table. I had better results with STAmina, I’d recommend that app over this one any day of the week.
  • Good training, good meditation drill Dec 5, 2018

    By osireuggjwoeirugwerk
    I started using this app as to augment my training for free diving. I find that it is also simply enjoyable. In a doctor’s waiting room, for instance, it’s a fun way to kill waiting time productively.

  • More flexibility on narration May 26, 2018

    By DustBunnyFossil
    My instructor has me inhale exhale hold, so that my hold is without any air in my lungs you should allow the user to change around those options with regards to your narration.
  • App use Apr 29, 2018

    By Joebuild
    The app is not intuitive. The explanation of setting it up is sort of vague. I think it needs more instruction or video on how to set it up and use it.
