2 new versions are released today, here is the list of changes below.

Apnea CWT

This is essentially a fix for a problem with Venu models that was causing a crash after a few seconds or minutes of use. If you don't have a Venu, there is no need to update Apnea CWT to version 2.0.2.

New supported devices

The list of supported watches is growing:

  • Descent MK2S
  • Forerunner 945 LTE
  • Fenix 7 series

Apnea DYN

Concerning Apnea DYN, it is a big update that includes the changes of Apnea CWT 2.0, here is the list of changes :

Change of the interface

When opening the application, you will notice that you are directly in the main screen: the main menu has been removed for simplicity. From now on, to access the settings or the about page, you will just have to press the UP button.

The menus have also been redesigned and prioritized to make it even easier to find items (on Fenix 3, the menus are flat due to the limited memory available).

Selecting the data to be displayed on the main screen

You can now choose which data to display on the main screen:

  • Heart rate
  • Oxygen saturation
  • Minimum temperature
  • Average temperature

This choice is relevant for those who practice in a natural environment with a wetsuit that prevents the optical sensor from functioning and who wish to know the water temperature.

Also note that the measurement of oxygen saturation in water should be interpreted with great caution.

Misc

  • Time display : This is something that has been requested a lot because not all models allow you to create a shortcut to display the clock from a third party application. The time has been added to the settings menu entry.
  • Choice of water density : This option allows you to specify the type of water you are immersed in to improve the accuracy of the measurement.
  • Changing the depth unit : Essentially useful for users who use their watches in imperial units but wish to use meters as the depth unit.
  • Feedback type : It is now possible to choose the type of feedback desired (sound, vibration or both)
  • Terminology change : The term cadence has been replaced by metronome to be clearer on its usefulness and in line with the terminology used by Garmin.

New supported devices

The list of supported watches is growing:

  • Vivoactive 4
  • Vivoactive 4S
  • D2 Delta
  • Forerunner 645
  • Forerunner 745
  • Venu
  • Descent MK2
  • Descent MK2S
  • Forerunner 945 LTE
  • Fenix 7 series

New models and depth measurement

Note on the new models recently released (Fenix 7, etc...): I have no feedback yet on depth measurements with them.
