Freediving Apnea Trainer

This was a very useful app that I enjoyed using, simple and effective. However, recently during training sessions the screen will close and when I unlock the phone the Play Store will be visible on some random app, as if I had clicked on an ad. This is completely unacceptable and stinks of rigging the app, not even mentioning the fact that it throws off the timer.

What's going on with this app??? It's impossible to close now. Even when you turn off the program, you get unremovable notifications that the app is still running. Pretty close to uninstalling it for this reason alone.

LOVE THIS APP! 3 weeks improved from 1:49 to 3:24 static hold. FEATURE REQUEST: A 'set departure' table. Where you can have a variable hold time opposed to a set time. Your one breath mode gets pretty close to what I'm looking for

I've been using this app for years, and it's still my favorite apnea trainer. I like the flexibility to create my own tables. Most other apps don't allow you to adjust ventilation and apnea time on the same table. Previous problems have mostly been ironed out. I learned through experience that voice prompts will be less accurate or skipped if you make the app tell you too much in quick succession, like signalling the start of contractions with 30s remaining, or setting an apnea time of 2:00.

I don't know how to explain it, but sometimes seconds run too fast. It is like the seconds in this app a bit shorter then real. Maybe I am crazy. I feel it every training. And one more. Every training I add one sec to holding time. Usually I have 8 laps, so I need 8 times to change the time (add 1 sec). It makes me crazy. Is there any way to change all laps at once?

so far so good. the only issue I have found is when I set the setting to use the sensor on my phone, it turns on the flashlight which is right above the heart rate sensor on my S7 which ends up burning my finger so I can't use it which is the only reason I don't give it 4-5 star. hope you guys can fix this bug as I really enjoy the app!

Great so far. In 3 days I have doubled my breath holding time (complete beginner). Only suggestion to app interface is when creating a new table, the trashcan for deleting a row gets covered up by the add new row button and is difficult to press. Might want to relocate 1 of the 2. Thanks so much for your work!

10-11-20 What a disappointment. I had hope the problem was with my phone, so I'd restart the phone prior to starting the exercise. It didn't help, the app would randomly stop during the later rounds (very frustrating). No way would I pay for the premium app if the free app is so flakey. Deleting the app from my phone. 9-29-20 What happened? The app was great, but has started to fail and exit in the middle of the training. The countdowns have also been glitchy. Is it my phone or the app?

I have been using this app for three years now, and I love it so much. It's easy to navigate through, and has all the settings I want it to have without being overcrowded with options. Also, big thanks to the developers for allowing the app to have such a minimal amount of advertisements. 10/10 would recommend this to anyone who'd ask!

Excellent app. Can't believe it's free. I just hope they put volume button mapping for the contraction button. Other than thay, everything's perfect. Edited: They really do have those button mapping for the contraction. So silly of me. Awesome App!

I enjoyed using this app on my android phone but now it doesn't have any audio at all. No audio notifications on how much time is left, or the hold and breath instructions on square breaths. I would really appreciate if you could help me with this problem.

Great app! Works well and interface is intuitive. I can confirm the app working nicely with a Huawei band 4. For the devs: the most recent firmware update of the band offers a one time SpO2 measure. It would be great if the app could tap into that data. Cheers!

The app is totally free which is great. You have 1 preset O2 and CO2 tables plus the ability to make your own. As well as a max breath hold timer and log to check up on progress. The app doesn't fail! What more could I want, they give what they promise.

Basic but good. The tables are customisable but a bit clunky - if you reset based on longest hold ,it reapplies it to everything, and if you want to make consistent changes you have to do it all individually. But otherwise it does all I need.

really good so far. I've had it for 6 days. first attempt 1.30 I adjusted the tables to my best time, did those after a day and got to 2.08 adjusted tables again and got to 2.27 did the new tables a day later and I just did 3.11 . looking forward to seeing how this goes , seeing massive progress after only a week. app is easy to use, liking it so far 👍

Tried this a year ago and reviewed it poorly. This is the cleanest interface apnea trainer and since redownloading I have had no issues. Opens several adds simultaneously with no input and crashes the app rendering it totally useless.

Very good app done by knowledgable people. Really helpful with clear voice instructions and count down during the training so we dont have to look at the screen. The max breath based auto calculation to update the tables is amazing.

I've used this app for a year and a half. It worked great. However, a recent phone update is causing crashes. Unfortunately, its no longer usable. I have a samsung s10e

PLEASE FIX! It goes to an add or asks you to rate it when in the middle of a table and resets the timer. It is very hard to use this as a training aid when its not reliable.

I used this app religiously in the previous years. However as of 2/1/21 the app force closes after 15 seconds of being open on my Samsung s9+. If this issue is remedied is take the review back to 5 stars Edit: I redownloaded the app and the forced shut down has been fixed. With this issue fixed, 5/5 stars!

The whole thing doesn't work after I disable the app to access to my mobile data. Managed to load into the interface but it doesn't have any response. Then the app shut off automatically.

The app worked perfectly at first, but now it automatically closes after about 10 seconds whenever I start a timer. Otherwise, the app is excellent.

I really want to use this app but it keeps crashing and closing out and not storing any data. Please fix the bugs soon I would pay for the premium if the bugs get fixed, btw i'm using a pixel 4xl with Android 11.

Good app, well thought out app. Easy to set up and use the tables. Integrating with HR and SPO2 is very nice. The ads are not intrusive, and sometimes relevant. Developers should consider creating an for HIIT that also integrates HR and SPO2. Thanks!

Really great app for apnea training, however, the breath up and breath hold are interchanged on the custom tables. Also with the update of Android Pie, my oximeter couldn't connect with my phone.
