Accessibility is great!!!

With many 3rd party CGM clients accessibility isn’t an option. The devs of Happy Bob went above and beyond. They not only fixed Voiceover issues, they fixed them quickly and asked me to test the Apple Watch app for VO compatibility. Great job and Happy Bov helps take the stress out of daily diabetes management.
