Usage

Login

When you open the app for the first time, you will be greeted with the login screen.

Since the Dexcom login requires a real account to fetch sugar values, skip the signin and click Test Mode.

The test mode will allow you to use the app without having to sign in to your Dexcom account by generating random sugar values.

Navigation

To navigate throughout the app, use the drawer found by clicking the hamburger icon in the top left.

Home screen

On the home screen, you will be shown your current sugar value, the sugar value recorded at the last meal, and a graph of your sugar values over time.

NOTE: If you used Test Mode, the graph will only be a ranodm jumble of dots. The following screenshot shows what it may look like in a practical application.

Ingredient Editor

The ingredient editor lets you set an ingredients name, carbs, and unit. Here, you can add, edit, or delete an ingredient.

Everything on this screen is automatically saved to the database.

Insulin Editor

Enter the insulin editor by first selecting a meal you would like to fill in. By default, today's date is selected.

If you would like to change the date, click the date button on the top. Click All Meals to go back.

You can start typing in the ingredient autofill box to filter, or click the caret to show the list of ingredients stored.

You can change the serving amount to automatically update the carbs.

You can click the x in the autofill box to delete an ingredient section.

If an ingredient is your main ingredient, toggle the main meal toggle. When a main meal is selected, if this is the first occurence of the ingredient as a main meal, nothing will happen. However, if this ingredient has been used before, the sugar value recorded for the next meal will be used to calculate a moving average to give you an overview of whether the carbs for the ingredient should be adjusted or not.

At the bottom of the insulin editor, you will see the current sugar value, carbs, and insulin dosage. If your settings haven't been set yet, you'll see an infobox letting you know that your insulin dosage can't be calculated until settings are set.

Recipes

At the main page of the recipes screen, you'll see a list of all recipes stored, remove buttons to remove a recipe, a button to add a recipe, and buttons to edit each recipe.

You can add a recipe by clicking the Add New button.

Inside, you'll find a setup similar to the insulin editor, but with a few differences. There is a section to set recipe metadata. The serving amount helps calculate the carbs per serving.

All recipes show up in the dropdown in the insulin editor so that you can directly import a recipe as one single object.

Settings

The settings screen lets you set I:C and ISF preferences. A common I:C ratio is anywhere between 10 and 15, and a common ISF factor is somewhere around 30.

You can click the show individual meal settings button to see the settings for each meal.

This screen does not autosave, click Save to save your settings.
