My New Years Resolution was to hold my breath for five minutes, and I decided this app was going to help me do it.
Ive only been using this app for two days, but here are some things Ive noticed.
1) The app does not explain itself very well. Sure, you can figure it out, but I feel a "Help" option could be added.
2) I think a sound should play (toggle on/off) when switching between Ventilation and Apnea during training. I dont like having to check the screen every minute or so to check my progress. However, there is probably an option for this somewhere in the settings.
3) In the "Graph" feature, I think it would be beneficial if the journal entry appeared upon tapping the time on the chart. This way, you would not have to continually switch menus.
Overall, I like the app and it was worth the money. The "Feedback Centre" seems to be broken; I get a white screen, and nothing more. Ill continue to use the app throughout the year, and I plan on writing more reviews as I become more familiar with the application.
