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.

Developer Response ,

Thank you for the feedback. We are really happy to hear you like the app! After living with diabetes for many years, we thought there has to a way to add more positive, fun elements to the daily life. It would be really nice to hear if you have any ideas how we could make Happy Bob even better. You can email us at Thanks again and best regards from the Happy Bob team.

Extremely Rude!

After downloading this app (on the recommendation of a friend) I was very excited to show it to my 8 year old type 1 diabetic daughter. At first she was overjoyed by the colors, fun choices of different faces and voices, and to hear fun comments with each BG test value. However, after 15 mins of using it we deleted it without regret. This app almost made my daughter cry by repeatedly telling her how “bad she was at taking care of herself” or how “she obviously doesn’t care about herself enough to stay in her target”. Keeping an 8 year old in their BG target range all day long is dang near impossible. This app may be fun for older teenagers or young adults but for young kids, save yourself from needing to comfort your child and do not download!!!!!

We are sorry you have had a bad experience with Happy Bob!
Happy Bob has several moods to choose from: Happy, that is suitable for all ages and then the more sarcastic moods Snarky, Karen and Robert S. Pumpkins.
For children and anyone who does not enjoy sarcasm we recommend Happy-mode, which is always gentle, supportive and kind.

Best diabetes management app

Other diabetes management apps are boring and can be anxiety-inducing. Happy Bob is exciting and feels more like a game than an app to help monitor a disease. The app is easy to set up and connect, it’s star system motivates and rewards, and snarky Bob is hilarious. I prefer Happy Bob hands down to similar apps that I’ve used in the past.
