Accessibility of the One Touch Verio Flex Glucose Meter App?

Does anyone know if the app for the LifeScan One Touch Verio Flex glucose meter is accessible with VoiceOver on an iPhone 8? I have the chance to get a free meter from my insurance plan but wanted to find out whether I could use the app or not, because I know that the meter doesn't talk. Thanks for any information you can provide.
