Very superficial
The app should have all the information in the manual for quick reference. It doesn’t. I have a constant blue light on the charger and should be able to reference the light meaning in the app. The app doesn’t show any light indicators meaning.
Not much data
This app is almost completely useless unless you lost the instructions that came with the lifevest. It does NOT allow you to see data related to the main function of the vest. No information about warnings or alarms.
