I am very happy that this appelsiner exists at all! Great work, neat to be able to do co2/o2 tables with my watch. The only thing I can't figure out yet is the o2%/pulseox measure. It remains stuck during my whole session (same as my last manual measurement). I normally have pulseox disabled, but for training for freediving, it would be neat to see. Do I have to change so my watch always measures pulseox to see this, or is there any way I can enable for this app only?

Hello Morten and thanks for your comment. The oxygen sensor is automatically activated when the application is launched (if the watch has one, of course), and stopped when the application is stopped, regardless of the configuration of this sensor in the system parameters. So if your oxygen saturation level does not change during exercise, it probably means that it remains stable, at the same value, for the duration of the exercise, which may be completely normal . Or, if you think that this rate should vary (depending on your practice), it could come from a problem initializing the sensor when starting the application but in principle, it should be activated when starting the app.

Unfortunately, I am not rating the quality of the app because it simply doesn’t work on my Descent G1 Solar even if this is flagged as compatible watch. I can install it and then, when accessing on my watch, I get “IQ!” Error message. I tried to uninstall/install several times, even after switch off and on the watch. Same results. Not sure, if this is recurrent issue on other same watches, an app issue, IQ issue.

Hello Camille and thanks for your feedback. Unfortunately, this is normal because this application is not yet designed for Instinct 2 and Descent G1 type models, it is an error and therefore your G1 model should never have been offered as a compatible model (possibly an automatic insertion by Garmin, or just my fault). I will check this and remove compatibility for this model today. Sorry for the disagreement.

Not useful for suba diving at all. Hard to make sense of and hard to get to what you want it to do.

Hello Anna. This app is not intended to be used for scuba diving, if this had been the case, the application would not have been authorized and validated by Garmin. This app is just for training out of water to practice breathing exercises that may help for your scuba diving activities.

25 Desember 2022 | Versi 1.66

Nice App. What would be perfect when by the Co2tabel the first Breathholdtime would be fix when I configure more cycle then the first Time with each reduce from 15 sec and so the last would be often 15 sec stay for the last 2 or 4 rounds

On Epix Gen 2 it is not starting anymore (it was working twice..), display shows IQ! I know, I should delete the app + the files and re-install it. But how often should I do this? Every week the same game, not working when l need it. So, the App is useless. I am going back to the "freediving" App on my phone.

Hello Tommy and thanks for your feedback. Your issue should be fixed now with the last release of the app (version 1.66). You can read the log file here: Sorry for this inconvenience :)

Hello 3DDD and thanks for your feedback. Can you please send me an email with the details of the circumstances of the issue please ? Which tables did you use ? The parameters of your table ? With all these infos, I will be able to test the app with the same data and try to reproduce the same issue. Thanks in advance.

It used to work well, but not anymore. When I try to start a table, the app freezes, and it displays the error: IQ!

Hello Jake and thanks for your feedback. The settings file of the app may not be no more compatible with your current version of the app. So, I suggest you completely delete the app and all its associated files (with the same name) then, fresh reinstall the app from the store.

Does not launch on Descent G1 Solar

22 Juli 2022 | Versi 1.59

Sur Fenix 5 SAPPHIRE APAC, fonctionne très bien. Si je peux me permettre une petite suggestion : serait-il possible d'ajouter 2 modes, respiration carré ( qui pourrait être aussi faite avec le plan free, je le conçois) et la respiration triangle ? En tout cas, appli très sympa pour découvrir ces exercices.

Just started using it on a Venu 2. I like it, but I cannot see the sp02 saturation data when i review the activity in the Connect app.

Balasan Pengembang
3 April 2022, Surfy66

Hello Chris, and thanks for your comment. SpO2 saturation is recorded and saved into the FIT file as graph display and, normally, you should see it in Connect app as Venu 2 is compatible with this kind of metrics. If not, you can contact me by mail, and we will try to find a solution to your issue. However, it seems that this feature works fine for the other users because I have no feedback about this, except yours. So, feel free to contact me.

I liked it on the first try. Setup of the tables is easy, and the watch face shows all the info that you could ask for. Is there any way to get the Prep and Hold times uploaded to Connect so that you can compare them to Heart Rate?

Balasan Pengembang
5 Maret 2022, Surfy66

Hello Jake and thanks for your comment. This feature already exists: PREP and HOLD times are saved as laps into the FIT file so, you can see them to the end of the lap table in your dashboard.

Display freezes on Vivoactive 4. The app continues to work in the background; if you swipe to the next screen and back you can see the time advance, but it's just a "snapshot", and vibration also ceases to function.

Maybe I just don't understand, but in 'Static tables' app first interval (before first hold) is short, but here we have to add like 1.5 - 2 min preparation before first hold. Is it by mistake or by design?

I like the concept as I use a apnea trainer on my phone. However, i cannot get the app to work on my fenix 3. When there is 15 seconds left on the prep countdown the IQ with exclaimation mark symbol appears on every mode and then freezes. How do we fix this?

Well, I love the idea of this app, but it just doesn't work in my watch. I'm currently using a foreruner 235 and when I click on start, it just freezes in the IQ logo

31 Juli 2020 | Versi 1.17

Great apps. I am using active4 for this app. I can record the necessary in my trainning. But sometimes, the display of my watch will stop to show the count down while the app is continuing. After a hole period, the watch can connect to phone and record the data of the past. However, it is a great app in apnea trainning.
