A Joy to Use

I cannot explain how much I love this app!!! You can tell that it was created by people who have real experience and understanding of what living with diabetes is like. I feel encouraged when my BG is both in and out of range and Bob’s comments about my blood sugar always make me smile, no matter how many times I see them. I’ve lived with T1D for 17 years and this honestly is one of my favorite management tools I’ve used.

Angels sent from heaven

Who are you angels and which part of heaven did you come from?!? This app is super fun and I love the sarcastic option! I’m wondering if I am missing a widget option? If I am, please let me know! If there isn’t, that’s my only constructive criticism! Thanks for making this crappy disease more fun!

Developer Response ,

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.
