  War W0lf: I can not recomend this enough. This is one of the best apks to pratice your breathing and breath holds. The developer is constantly making imporvements on this apk and the usability of the apk is good. Would like some more guide videos however. Like breath up etc. Buy full ver unbelievable

  Ed Eilerts De Haan: Good apk for those doing any form of apnea training. Used the gratis ver for months before deciding to make batter the apk along with my smartphone, only to realize it doesn't yet help generic Bluetooth 4 HR monitors. My fault for not checking first, so I can't fault the apk. Massively looking forward to when that gets implemented! Hold up the awesome work!

  Ahmad Fauzi Purwandono: Best Apk for training so far. But is it possible to create a countdown voice after 30 second breath up remaining? so I can focus in my breath not looking on my smartphone, thanks. :)

  Nathan L: Apk is good but needs polishing. Some of the articles link to dead links. Still one of the best on the market.Would like to see a calendar for training and a way to log another Freediving training.

  A Google user: Upon further testing with a galaxy s4. I have found that the heart rate data is recorded with the finger way, an ANT+ heart rate monitor, and a Polar heart rate monitor; however when reviewing the collected data in the graphs both the heart rate monitors only display the initial point at zero bpm and no more points. The awesome news is that the finger way records perfectly. Scrolling around and manipulating the graphs is difficult and hard on the s4. Will try on s3 and s2 as well. Don't have a zephyr. As of 26 Apr 2015 the Ant+ heart rate monitor is working good. Moving side to side in the graphs work well however when zooming in you cannot move up and down. Bumped up to 4 stars.

  Luuk Driessen: Finally an apnea apk that adds best of both worlds. My Cheap China Coospo Hear rate BT smart sensor works ok. Need to pair one time manually in Android device and then it is found by the apk. Only thing, in the overview I can't see when pressed for a contraction. Another than that, good apk!

  plinkertin: I am a fanatic off the apk, but when is the Bluetooth Smart Device function going to be accessible? The apk tells me it has been under construction. It has been that was for a lot of a lot of months. I could have stuck with the gratis ver of this apk.

  Ludo matic: ...should it be possible to simply rename a table (long press) and re-order tables list manually ? Also, while in exercise, to have the current table progress (like eg. "round 3/8" or the whole table detail with current round highlighted) ? Rest of the apk is cool and usefull, thank you!

  Alphonse Faure: The apk looks like a useful program but it is terrible to use. Setting up tables is convoluted and difficult to figure out. Developer included instructional video but decided to create sure his voice was drowned out by melody. I'm hopeful future versions will be refined and worth purchasing. The current ver is not.

  Víctor Emilio Esteve: The method to build the tables is very primitive, the menu disappeared on fresh Android device. It is unusable now. Please fix.
