Glucobyte is a diabetes app that allows you to record, track blood sugar, analyze and share your blood glucose information using your mobile device. In addition, Glucobyte connects with Apple Health. With your health information at your fingertips, you can now take active control of your own health. Whether Prediabetic or Type 1 or 2 diabetic, Glucobyte can help you manage all your blood glucose, A1C, insulin, medication, ketone levels, carbs and weight information to monitor your progress and discover trends with an overall goal of improving your blood glucose.

1) Glucobyte al­lows you to record, track and an­a­lyze trends in your blood glucose information. You can ei­ther man­u­al­ly en­ter your records or sync with Glucobyte through Apple Health. Glucobyte alone does not mea­sure blood glucose or blood sugar. You need a sep­a­rate blood glucose meter to mea­sure blood glucose levels.

2) Glucobyte is NOT a substitute for a doctor or professional healthcare or advice. Any health related information provided is for informational purposes only and should not be used to replace the advice of healthcare professionals.

For information on how to use the app, visit our website FAQ:


- With Glucobyte Diabetes Tracker, Record and track blood sugar (mg/dL or mmol/L), Insulin basal or bolus (Units or mg), Medication, Ketone, Carb counter and Weight. Estimated A1C is automatically calculated for a selectable time range. Modify date and time for records as needed.

- Quickly add notes and tags (e.g. fasting, before/after breakfast) using tags. Tags are intelligently pre-populated based on a configurable meal timing and remember medications for quick and easy entries.

- Store and access all your blood glucose measurements anywhere and anytime using Apple Health.

The following Glucose meters can connect to HealthKit (check for compatibility with different models):
* Dexcom

Best diabetes app I have used

I have tried out the number of glucose monitoring apps in the past. This one is very intuitive and easy to use. All of the features are easy to navigate, and the graphs/data representation are clear. Best of all, I am not linked to a particular brand of monitor to store all of my data. Furthermore, the analytics are well designed and help me adjust my lifestyle as needed.

Maybe someday

I did not know this was a brand new app when I paid for it.
Has potential but not there yet.

Take medications for example:

You need to have on a list of your medications on sheet of paper beside you. There is no list for you to choose from which mean you have to type the name in from scratch
Not Once but every time you take a med you have to type in the name of the medication.

Graphics are good but I can believe that after at least two years of updates they are not further along

Yes they sync insulin data to Apple Health BUT they do NOT distinguish between the two insulin types


See Apple Health Insulin Delivery input for excellent description of Bolus & Basel

I take BOTH types

Developer Response ,

Update Apr 16th, 2021: In version 2.4, you will be able to Remember medications for quick and easy entries through an editable and searchable list.

Update Mar 2nd, 2021: We have improved Glucobyte based on some of your recommendations. Check out version 2.3 which will be released in the app store shortly.

Key improvements:
1) Save insulin as basal or bolus and details recorded in PDF reports and CSV files.
2) Sync insulin basal and bolus entries with Apple Health.
3) Remember meds enabled by default.
4) Medicine dosage entry allows decimal values.
5) Remember previous weight entry that allows quick weight updates.
Jan 28th, 2021, Thanks for identifying opportunities for improving the medicine list and adding insulin basal and bolus. We will update it in a future revision.

Also, just so you know we released the app only 3 months ago. Therefore, not sure where the graphs reference of 2 years came from.
