How To Use Diabetes 360

You will find detailed instructions below for the setup and use of Diabetes 360. We are always available to help as well if you would like to Contact Us with questions, comments, or suggestions.

These links can be used to quickly jump to a section:


This is the main settings page where you can access all of the configuration and setup for Diabetes 360. Rows with a blue circle and chevron can be tapped to show more information.

It is important that all settings are set by advisement of your physician. Never use Diabetes 360 without this advice or without validating that the dosing it recommends is the same as what you would expect from manual calculations for insulin dosing.

Browse the sections below for details on each section of the main settings page.

Dose Calculation

Tap Formula or Scale, then tap the row or blue circle. Instructions for each are below.

Glucose Unit

Select the button that reflects the unit of measure you wish to use for your glucose—mg/dL (most common) or mmol/L All glucose values will be presented and entered using this unit of measure. mg/dL values are usually in the range 0 to 600 mmol/L are 0 to approximately 40.0


Prescribed Insulin

The Prescribed Insulin page allows you to tell Diabetes 360 what types of insulin you use. They are grouped by how they are classified by the medical community (Rapid, Short, Long, Intermediate, Mixed, etc). One type per group may be selected which will be indicated by a check mark. It can then be used on the Log Entry page.

The Long-Acting classification has an "Hourly Interval" editable field. The number you specify here will be used to schedule a reminder to administer your next dose of insulin. The reminder is set this number of hours after the last dose of long-acting insulin is logged.

The "Oral" and "Miscellaneous" sections allow multiple Insulin Brands to be selected. All other sections allow only one brand per section to be selected.


Dose Calculation

The Dose Calculation row has a button for “Formula” and “Scale”. Select which method you are currently using.

Formula (Insulin Factors)

There are three factors which must be set in order for Diabetes 360 to properly calculate your insulin dose using glucose and carbohydrate—Target Rate, Corrective Factor, and Carbohydrate Factor.

Physicians will sometimes have their patients vary these factors throughout the day. If you are such a patient, tap below the section and a new row will appear. Tap the new row to set the time to start using the factor on that row. The time will appear in red while editing it. If your factors are the same all day, just tap the number at the right of the row and enter your value--no need to add aditional time rows.

In the example to the right, from 4:00am to 9:59am the Target Rate will be 120, from 10:00am to 3:59pm it will be 150, and from 4:00pm to 3:59am it will be 90.

It is critical that these are entered properly and that you validate the calculations Diabetes 360 performs against your own. Once you are comfortable that the correct dose is being calculated, let the app advise you, but always consult your physician in managing your diabetes.

The factors are visible on the Log Entry page as you enter your glucose and carb figures while logging a dose. Swipe across a row to delete it or use the edit button.

The formula used by Diabetes 360 is:

Units of Insulin = ((Glucose - Target Rate) / Corrective Factor) + (Carbs / Carbohydrate Factor)

If there is a different formula you use, please Contact Us and we will send an update allowing you to use other formulas.

Sliding Scale

Some patients use a sliding scale, especially in the early stages of the diagnosis and treatment. Type 2 patients frequently use this method. Tap “Scale” and tap the row (outside the button). This page gives you four rows. If you need more rows or less rows, add or delete to match your scale. Then enter the dose for each range in the fields to the right-hand side. In sliding scale mode, carbohydrates are not used for the dose calculation though meals can still be built from the food database.

To alter the scale, either edit the rows directly or tap the "Edit" button to add or delete them. When adding a new row, you must enter both the lower value for the range as well as the insulin units for the row to be added.

You can also swipe across a row to delete it.



Diabetes 360 comes with pre-loaded sites to choose from when logging. They can be deactivated from here so they will not appear in the picker when adding or editing a log entry. Tap the row of the site to activate or deactivate it.

This is useful if you do not use a particular site and will prevent it from always appearing at the top of the list when picking a site from the log entry screen.


The Reminder System

Daily Schedule

There is a comprehensive but simple reminder system built into Diabetes 360. The Daily Schedule is at its core.

There are default items included which can be altered for your personal needs. Tapping a row allows you to set the details of each item. If you would like a reminder at the Begin Time, slide the on switch and you will be reminded each day at that time. If you have to eat carbs or dose insulin, enter it on this page and the reminder will notify you.

The Any Time switch is for logging exercise or other things that may impact your glucose levels. The Begin and End Time are ignored for items with “Any Time” set. Swipe to delete a row.

A Badge indicating the number of reminders set will appear on the Diabetes 360 icon.

Pump Site Change

Simply select the date of the last change, the time you wish to be reminded, and how often you change sites. You can verify the dates you will be reminded from the “Browse Upcoming Reminders Page”


Reminder Browser

We have included a page to view all reminders that are currently set. There are three types: those set from the Daily Schedule, those from the Pump Site Reminder, and the Long-Acting Insulin reminder. You may delete the Long-Acting Insulin type of reminder from this page, however the other types must be changed from where they were set.

The Diabetes 360 icon will have a badge reflecting the number of reminders that are set. The Pump Site Change reminders count as one. The number of rows in the table on the right will always equal the number on the badge on the icon; in this case 6.

Insulin On Board Factors

When there is residual insulin in your body from a prior dose, this can be accounted for by Diabetes 360 using this settings page.

The hourly numbers on the left represent the time since the last dose of rapid-acting insulin. The percentages on the right represent the percentage of the prior dose that will be subtracted from the current dose.

For example, if 2.50 hours ago, 11.30 units of rapid-acting insulin was logged into Diabetes 360 and, based on blood glucose and carb intake, 6.40 units is suggested now, Diabetes 360 would take 20% of the prior dose and subtract it from the current dose.

6.40 - (11.30 x 20%) = 6.40 - 2.26 = 4.14 units

It is very important that you consult your physician to set these values and to validate that the calculations are what you expect !!!

When a new entry is logged, the math used to arrive at the current dose is clearly shown on that page.

Exercise Factors

On the Add/Edit Log page, there is an icon to set your excercise level. The settings for Excercise Factors are used to specify how much to reduce or increase your rapid-acting insuln dose for a particular level (Light, Medium, Heavy). The dose is muliplied by the value in the right-hand column that corresponds to the level you have selected when entering the dose.

As with all setttings in Diabetes 360, be sure to consult your physician for your personal values.

Miscellaneous Settings

Rounding Accuracy

You may need to adjust how Diabetes 360 rounds the insulin doses it calculates and displays. Some patients dose in half units others using pumps may have more granular dosing. A value of 0.5 in this row will round to the half unit, 0.1 to the nearest tenth unit, 0.01 to the nearest hundredth, etc.

These are some examples of how the insulin dose will be rounded using various rounding accuracies:

  0.500 0.100 0.010
6.425 6.5 6.4 6.43
5.827 6.0 5.8 5.83

While Diabetes 360 will accept numbers such as 0.4, 0.52, etc, these will yield meaningless rounding results and we recommend avoiding them.

Ketone Threshold

Diabetes 360 will prompt you to enter the results of your Ketone test if the glucose value entered is above this value.

Picker Time Interval

There are several pickers in Diabetes 360. You can set how many "ticks" there are on these. A value of 10 would cause the pickers to display 00, 05, 10, 20, 30 ... This can speed up logging. The default value is 5.

Show Welcome Screen

If you need to see the Welcome Screen you saw when you first purchased Diabetes 360, it can be accessed here.


Add or Edit Log Entry

This page is the core of Diabetes 360. It allows you to log your glucose level and carbs and quickly determine the amount of insulin to administer.

Each time you key a digit in either the Glucose or Carb box, the insulin dose is recalculated and rounded according to the settings you specified on the initial setup. As you key digits in the Glucose and Carb boxes, the formulas and results adjust so you can see exactly how the dose was calculated. To bypass Insulin On Board adjustment, tap the IOB icon or tap the excercise icon to adjust for level of exercise. The factors used for IOB and Exercise are accessed from the settings page.

Leave Glucose or Carb blank if you are not using the value for this log entry. Blank values are ignored in all averages and graphs. For carbs, enter zero if you ate zero carbs and wish for that value to be included in the averages.

To key a value for the insulin dose rather than keeping the suggested amount (in green). Tap on the dose suggestion (5.37 at right) and key the actual amount administered. To revert back to the calculated amount, alter the value in either the glucose or carb box. (version 1.03 and above only)

You will see this cell displayed only when a rapid-acting insulin is selected. For other insulin types, you should dose according to your doctor's instructions as the app suggests. If there is some other formula that you use for rapid-acting insulin, Contact Us and we will send an update that allows you to set the formula to your own.

If you are using a sliding scale. Go to the settings page and select “Scale” for “Dose Calculation”. Tap the row and enter the values from your physician. Once you have set up your sliding scale, it will be used instead of the formula. In sliding scale mode, carbohydrates are not used for the dose calculation though meals can still be built from the food database.

All parts of this page are modifiable by a tap just as the glucose and carb boxes are.

The Log Time can be adjusted by tapping it as can the Time of Day just below it. The values for Time of Day are set in the “Daily Schedule” on the settings page. These can be used in the export criteria and will also be part of the analytical feature that we are currently finishing. Go ahead and use them so that when this exciting new feature is published, your log entries will yield meaningful data.

Diabetes 360 has a carbohydrate database built in that is accessible by tapping outside of the Carbs box. These pages allow you to find foods you are going to eat and build a meal. See below for a complete narrative of the features available.

Tap the insulin row on the left side to specify which brand of insulin was used for this dose. Tap the right side of this row to set the injection site. If you select an insulin type that is not rapid-acting, the formula will be replaced with instructions to “Take as Prescribed”. Selecting a long-acting insulin will schedule a reminder according to the settings.

Injection Sites are ordered with the least used at the top. The percentages reflect how often each site has been used relative to the total sites used.

If you did not set up the insulin prescribed to you, an alert will be presented so you can set them up and return to the Add Log Entry page. When the insulin brand is tapped, a picker will be displayed containing the insulin brands you selected in the settings.

If you have entered a value for glucose that is greater than the “Ketone Glucose Threshold” in the settings, Diabetes 360 will display a picker to allow you to log the result of your ketone test. Consult your physician for the value to set for this. The Ketone Test results can be set manually by tapping the Ketones row. If you select "Moderate" or "Large", you will be reminded to drink plenty of water.

There is an area at the bottom for free-form notes. These are included in the export output (email, csv files).

Tap the “Save” button to store the log entry. The values you entered are automatically used to adjust the averages and other statistics built into Diabetes 360. Be careful not to tap cancel as this will cause the entry to be discarded.


The USDA Carbohydrate Database

Diabetes 360 is packaged with a food database to allow you to build meals as you have them. No network or cellular service is required to use the database. It is on your device—waiting for you. To use it, simply tap the Carbs label on the Log Entry page. You will be presented with a list of foods from the US Department of Agriculture SR23 nutrition data file.

Select Foods For the Meal

The first step is to select the foods you will eat, once selected, tap the “Servings” button and a page will appear that allows you to adjust how much of each food you are eating.

There is a search feature as well. Tap the search bar and enter a word or words that describe the food you seek. Diabetes 360 applies a logical "and" when searching the descriptions for the words entered (the food description must have all the search words anywhere in the description). Experiment with this to get a feel for what search words yield what results. The status bar (where the clock is) can be tapped to quickly bring the search bar back into view after scrolling.

Notice the “Most Used” button.
Initially this won't do much, however as you use the Diabetes 360, it will track how often you have eaten each food. When "Most Used” is active, the most frequently eaten foods will appear at the top of the list. It is also important to note that search words are applied against the "Most Used" list when in this mode. Select "All" to exit this mode and work with the full database.

When all foods you plan to eat have been selected, tap "Cancel" to exit search mode and tap "Servings" to adjust how much of each selected food you will eat.


Adjust Serving Sizes

On the servings page each selected food is presented. Tap a row and available serving sizes appear in a picker at the bottom. Adjust this as close as possible to what you eat. As the wheels are moved, the carbohydrate for that food as well as the total for the meal are updated. To remove a food, swipe it or go back to the foods list and uncheck it by tapping it.

The total carbohydrate is seamlessly brought into the log.


Monthly Summary

Each section of this page has a summary for all the log entries for a given month. The green numbers are averages and the black are high and low. The bars show where the average falls relative to the high and low for the month.

Tap the white rounded rectangles to show detail for that month.

Monthly Detail

This is where individual log entries are accessible for review or edit. The black numbers are the glucose (top) and carb (bottom) on the log entry. The red and green bars are the monthly average as above for glucose and carb respecitvely. The red and green circles represent where the glucose and carb values fall relative to the monthly average, high, and low.

Tap a row to display or edit the log entry.


Reporting and Analytics

Hour of Day Averages

The graph shows each hour of the day for the selected time period on the green plot. The yellow bar represents the minimum target rate minus 25% and the maximum plus 25%.


Export To Email

This feature allows you to extract the entire database or a portion of it and email it to yourself, your doctor, or anyone else who might be interested. The email will have each log entry, any foods associated with it, and two comma separted value (CSV) files attached. These can be imported into a spreadsheet for more advanced statistical analysis.

Please do not hesitate to Contact Us if you need assistance with or would like to suggest enhancements to Diabetes 360. We pride ourselves on setting an example where customer service and product quality are concerned. We look forward to hearing from you.
