How to log a meal

Logging a meal in Diablesse is quick and intuitive. Here's how:

1. Open the Diary

In the Diary tab (book icon), tap the + button in the top-right corner.

2. Enter your blood glucose (optional)

If you measured your glucose before the meal, enter the value. This allows the bolus calculator to work correctly.

3. Search for foods

In the search field, type the name of the food.

Tip: You can type partial words — "whole wheat bread" finds "Whole Wheat Sandwich Bread".

4. Select the portion

Choose the unit and quantity you consumed. You can adjust portions precisely.

5. Add more foods

Repeat the process for each food in the meal. All items are listed with the total carbs and calories.

6. Calculate the bolus (optional)

If the bolus calculator is active in your profile, tap Calculate Bolus to get a dose suggestion.

7. Save the meal

Tap Save to log it. The meal will appear in your Diary with date and time.

How to use the Favorite Foods list

The favorite foods list was created to speed up filling in your diary. By favoriting the foods you consume most often, they will appear highlighted on the meal screen, so you don't need to search for them every time.

How to add a food to favorites

1. Go to the Favorites screen
   In the bottom bar of the app, tap the Favorites icon (⭐).
2. Add a new favorite
   Tap the + (plus) button in the corner of the screen.
3. Search for the food
   Type the food name in the search field. The app searches the food database (already adapted to the language selected in settings).
4. Select the food
   Tap the correct result. The food will be automatically saved to your favorites list.

Where favorite foods appear

When adding a new diary entry (meal or snack), favorite foods are pre-displayed at the top of the food selection screen. This lets you add them quickly without searching again.

Managing your favorites list

Practical example

If you usually eat rice, beans, chicken, and salad for lunch:

1. Add each of these foods to favorites once
2. When logging a new meal, all of them appear at the top of the list
3. Just select what you ate — no need to search

💡 Tip: Keep between 10 and 20 favorite foods to avoid cluttering the list while still including your most frequent items. You can edit the list whenever your eating habits change.

⚠️ Note: Favorite foods are linked to your profile. When switching devices or reinstalling the app, your list will be restored if you're logged into the same account.

How to customize diary entry fields in Diablesse

To make filling in your diary faster and more focused, you can hide fields that are not relevant to your daily routine. This way, when adding a new entry, you only see the information that actually matters to you.

Accessing the customization

Go to Settings in the main menu and select Entry Fields.

How it works

In the Entry Fields screen, you'll see a list of all available fields for diary entries (such as glucose, carbs, insulin, medications, notes, etc.).

For each field, you can:

• Keep active — the field will appear on the entry screen
• Uncheck/hide — the field will be removed from the entry screen, simplifying the form

Practical example

Saving changes

After checking or unchecking the desired fields, tap Save (if available). Changes are applied immediately to the new entry screen.

💡 Tip: You can reactivate any field at any time by coming back to this screen. Customization does not delete old data — it only redefines which fields appear for new entries.

How to use Favorite Meals

Favorite meals let you save complete combinations of foods you frequently eat together. When logging a meal, you can add all items at once, speeding up the process and ensuring consistency.

Difference between Favorite Foods and Favorite Meals

How to create a Favorite Meal

1. Go to the Favorites screen
   In the bottom bar, tap the Favorites icon (⭐).
2. Select the Meals tab
   At the top of the screen, switch to the Meals tab (next to "Foods").
3. Add a new favorite meal
   Tap + to start creating.
4. Name your favorite meal
   Examples: "Full breakfast", "Quick lunch", "Afternoon snack", "Standard dinner".
5. Add the foods that make up the meal
   • Search and select each food from the database
   • Enter quantities (servings, grams, units)
   • Repeat until all items are included
6. Save the favorite meal
   Tap Save to finish.

How to use a Favorite Meal when logging

1. In the diary, tap Add entry and select Meal.
2. On the food selection screen, find the Favorite Meals section.
3. Tap the desired favorite meal.
4. All foods from that combination are added automatically.

✅ The total carbs will be calculated based on all included foods.

Editing or removing items during logging

Even when using a favorite meal, you keep full control:

💡 Changes made during logging do not affect the original favorite meal. They only apply to that specific entry.

Bolus Calculator

Diablesse's bolus calculator uses a clinically established formula to suggest mealtime insulin doses.

Formula used

The calculation is split into two parts:

Meal bolus:

Total meal carbs ÷ Insulin-to-carb ratio

Correction bolus:

(Current glucose − Target glucose) ÷ Sensitivity factor − IOB (insulin on board)

The total bolus is the sum of both, always rounded down (floor) for safety.

How to configure

Go to Settings → Profile → Bolus Calculator and enter:

• Insulin-to-carb ratio — how many grams of carbs 1 unit of insulin covers (e.g. 15)
• Sensitivity factor — how many mg/dL 1 unit of insulin lowers blood glucose (e.g. 50)
• Minimum and maximum target glucose — your desired glucose range (e.g. 80–170 mg/dL)
• Insulin duration — how many hours your rapid-acting insulin lasts (e.g. 4h)
• Maximum bolus — safety limit for the suggestion

Insulin on board (IOB)

IOB is calculated automatically based on your last logged bolus and the configured insulin duration. It is only subtracted from the correction bolus, never from the meal bolus.

Important disclaimer

The calculator provides only a suggestion based on your settings. Always confirm with your doctor or diabetes educator before adjusting doses.

Estimated HbA1c: what it is and how to use it

The estimated HbA1c is a calculation automatically generated by the app based on the glucose readings you log in the diary. It provides an approximate view of your glucose control over the past weeks.

How it is calculated

The app uses the average of your logged glucose readings and applies a standard formula to estimate the equivalent glycated hemoglobin (HbA1c) value.

🔍 Important: The result is an estimate, not a lab test.

Important limitations

The accuracy of the estimated HbA1c depends directly on the quality of your records:

⚠️ The more complete and frequent your diary is, the closer the estimate tends to be to reality. However, it never replaces a laboratory blood test.

Reference values

💡 Consult your doctor to know what the individualized goal is for your case.

How to use this feature

✅ Good for:

• Tracking trends between appointments
• Seeing if changes in routine or medication are having an effect
• Getting an overview of your glucose control

❌ Not suitable for:

• Diagnosing diabetes
• Adjusting medications without medical guidance
• Replacing a laboratory HbA1c test

🧪 Recommendation: Continue having your lab HbA1c test every 3 months (or as directed by your doctor). Use the app's estimated HbA1c as a continuous thermometer between tests.

⚠️ Important disclaimer: The estimated HbA1c is provided for monitoring and awareness purposes only. It does not replace medical evaluation. Any decision about adjusting medications, diet, or insulin must be made exclusively with guidance from your doctor or healthcare team.

How to adjust the glucose range in the app

The glucose range defines the limits considered "normal" for your readings. The app uses these values to classify your glucose levels, generate alerts, and track trends.

Accessing the setting

Go to Settings in the main menu and select Glucose Range.

Option 1: Use quick presets

The app offers three presets based on clinical guidelines. Just select the one that best applies to your situation:

💡 The values above are general references. Your doctor may recommend different ranges based on your treatment.

Option 2: Manual custom adjustment

If you prefer or have specific medical guidance, you can set manually:

• Low limit — minimum value considered normal
• High limit — maximum value considered normal

Tap the corresponding fields and type the desired numbers.

Saving changes

After choosing a preset or manually adjusting the limits, remember to tap Save to apply the new settings.

⚠️ Important: Consult your doctor before modifying the glucose range, especially if you use automatic alerts or the bolus calculator. Poorly adjusted ranges can generate incorrect notifications or inappropriate guidance.
